# salt.modules.dockermod

Warning

This module will be removed from Salt in version 3009 in favor of the docker Salt Extension.

Management of Docker Containers

Added in version 2015.8.0.

Changed in version 2017.7.0: This module has replaced the legacy docker execution module.

depends:

  docker Python module

Note

Older releases of the Python bindings for Docker were called docker-py in PyPI. All releases of docker, and releases of docker-py >= 1.6.0 are supported. These python bindings can easily be installed using `pip.install`:

    salt myminion pip.install docker

To upgrade from docker-py to docker, you must first uninstall docker-py, and then install docker:

    salt myminion pip.uninstall docker-py
    salt myminion pip.install docker

## Authentication

If you have previously performed a `docker login` from the minion, then the credentials saved in `~/.docker/config.json` will be used for any actions which require authentication. If not, then credentials can be configured in any of the following locations:

- Minion config file

- Grains

- Pillar data

- Master config file (requires `pillar_opts` to be set to `True` in Minion config file in order to work)

Important

Versions prior to 3000 require that Docker credentials are configured in Pillar data. Be advised that Pillar data is still recommended though, because this keeps the configuration from being stored on the Minion.

Also, keep in mind that if one gets your `~/.docker/config.json`, the password can be decoded from its contents.

The configuration schema is as follows:

    docker-registries:
      <registry_url>:
        username: <username>
        password: <password>

For example:

    docker-registries:
      hub:
        username: foo
        password: s3cr3t

Note

As of the 2016.3.7, 2016.11.4, and 2017.7.0 releases of Salt, credentials for the Docker Hub can be configured simply by specifying `hub` in place of the registry URL. In earlier releases, it is necessary to specify the actual registry URL for the Docker Hub (i.e. `https://index.docker.io/v1/`).

More than one registry can be configured. Salt will look for Docker credentials in the `docker-registries` Pillar key, as well as any key ending in `-docker-registries`. For example:

    docker-registries:
      'https://mydomain.tld/registry:5000':
        username: foo
        password: s3cr3t

    foo-docker-registries:
      https://index.foo.io/v1/:
        username: foo
        password: s3cr3t

    bar-docker-registries:
      https://index.bar.io/v1/:
        username: foo
        password: s3cr3t

To login to the configured registries, use the `docker.login` function. This only needs to be done once for a given registry, and it will store/update the credentials in `~/.docker/config.json`.

Note

For Salt releases before 2016.3.7 and 2016.11.4, `docker.login` is not available. Instead, Salt will try to authenticate using each of your configured registries for each push/pull, behavior which is not correct and has been resolved in newer releases.

## Configuration Options

The following configuration options can be set to fine-tune how Salt uses Docker:

- `docker.url`: URL to the docker service (default: local socket).

- `docker.version`: API version to use (should not need to be set manually in the vast majority of cases)

- `docker.exec_driver`: Execution driver to use, one of `nsenter`, `lxc-attach`, or `docker-exec`. See the Executing Commands Within a Running Container section for more details on how this config parameter is used.

These configuration options are retrieved using `config.get` (click the link for further information).

## Executing Commands Within a Running Container

Note

With the release of Docker 1.13.1, the Execution Driver has been removed. Starting in versions 2016.3.6, 2016.11.4, and 2017.7.0, Salt defaults to using `docker exec` to run commands in containers, however for older Salt releases it will be necessary to set the `docker.exec_driver` config option to either `docker-exec` or `nsenter` for Docker versions 1.13.1 and newer.

Multiple methods exist for executing commands within Docker containers:

- lxc-attach: Default for older versions of docker

- nsenter: Enters container namespace to run command

- docker-exec: Native support for executing commands in Docker containers (added in Docker 1.3)

Adding a configuration option (see `config.get`) called `docker.exec_driver` will tell Salt which execution driver to use:

    docker.exec_driver: docker-exec

If this configuration option is not found, Salt will use the appropriate interface (either nsenter or lxc-attach) based on the `Execution Driver` value returned from `docker info`. docker-exec will not be used by default, as it is presently (as of version 1.6.2) only able to execute commands as the effective user of the container. Thus, if a `USER` directive was used to run as a non-privileged user, docker-exec would be unable to perform the action as root. Salt can still use docker-exec as an execution driver, but must be explicitly configured (as in the example above) to do so at this time.

If possible, try to manually specify the execution driver, as it will save Salt a little work.

This execution module provides functions that shadow those from the `cmd` module. They are as follows:

- `docker.retcode`

- `docker.run`

- `docker.run_all`

- `docker.run_stderr`

- `docker.run_stdout`

- `docker.script`

- `docker.script_retcode`

      - `Already_Pulled` - Layers that that were already present on the Minion

      - `Pulled` - Layers that that were pulled

    (Only present if the image specified by the "repository" and "tag" arguments was not present on the Minion, or if cache=False)

  - `Status` - A string containing a summary of the pull action (usually a message saying that an image was downloaded, or that it was up to date).

    (Only present if the image specified by the "repository" and "tag" arguments was not present on the Minion, or if cache=False)

  A dictionary containing the following keys:

  - `Id` - ID of the newly-created image

  - `Image` - Name of the newly-created image

  - `Time_Elapsed` - Time in seconds taken to perform the commit

salt.modules.dockermod.compare_container(first, second, ignore=None)

  This function is an alias of `compare_containers`.

  > Added in version 2017.7.0.

  > Changed in version 2018.3.0: Renamed from `docker.compare_container` to `docker.compare_containers` (old function name remains as an alias)

  > Compare two containers' Config and and HostConfig and return any differences between the two.

  > first

  >   Name or ID of first container

  > second

  >   Name or ID of second container

  > ignore

  >   A comma-separated list (or Python list) of keys to ignore when comparing. This is useful when comparing two otherwise identical containers which have different hostnames.

  > CLI Examples:

  >     salt myminion docker.compare_containers foo bar
  >     salt myminion docker.compare_containers foo bar ignore=Hostname

salt.modules.dockermod.compare_container_networks(first, second)

  Added in version 2018.3.0.

  Returns the differences between two containers' networks. When a network is only present one of the two containers, that network's diff will simply be represented with `True` for the side of the diff in which the network is present) and `False` for the side of the diff in which the network is absent.

  This function works by comparing the contents of both containers' `Networks` keys (under `NetworkSettings`) in the return data from `docker.inspect_container`. Because each network contains some items that either A) only set at runtime, B) naturally varying from container to container, or both, by default the following keys in each network are examined:

  - Aliases

  - Links

  - IPAMConfig

  The exception to this is if `IPAMConfig` is unset (i.e. null) in one container but not the other. This happens when no static IP configuration is set, and automatic IP configuration is in effect. So, in order to report on changes between automatic IP configuration in one container and static IP configuration in another container (as we need to do for the `docker_container.running` state), automatic IP configuration will also be checked in these cases.

  This function uses the `docker.compare_container_networks` minion config option to determine which keys to examine. This provides flexibility in the event that features added in a future Docker release necessitate changes to how Salt compares networks. In these cases, rather than waiting for a new Salt release one can just set `docker.compare_container_networks`.

  Changed in version 3000: This config option can now also be set in pillar data and grains. Additionally, it can be set in the master config file, provided that `pillar_opts` is enabled on the minion.

  Note

  The checks for automatic IP configuration described above only apply if `IPAMConfig` is among the keys set for static IP checks in `docker.compare_container_networks`.

    Name or ID of first container (old)

  second

    Name or ID of second container (new)

  CLI Example:

    Create the parent directory on the container if it does not already exist.

  RETURN DATA

  A boolean (`True` if successful, otherwise `False`)

  name

    Container name

  source

    File to be copied to the container. Can be a local path on the Minion or a remote file from the Salt fileserver.

  dest

    Destination on the container. Must be an absolute path. If the destination is a directory, the file will be copied into that directory.

  exec_driverNone

    If not passed, the execution driver will be detected as described above.

  makedirsFalse

    Create the parent directory on the container if it does not already exist.

  RETURN DATA

  A boolean (`True` if successful, otherwise `False`)

salt.modules.dockermod.create(image, name=None, start=False, skip_translate=None, ignore_collisions=False, validate_ip_addrs=True, client_timeout=60, **kwargs)

  Create a new container

  image

    Image from which to create the container

  name

    Name for the new container. If not provided, Docker will randomly generate one for you (it will be included in the return data).

  startFalse

    If `True`, start container after creating it

    Added in version 2018.3.0.

  skip_translate

    This function translates Salt CLI or SLS input into the format which docker-py expects. However, in the event that Salt's translation logic fails (due to potential changes in the Docker Remote API, or to bugs in the translation code), this argument can be used to exert granular control over which arguments are translated and which are not.

    Pass this argument as a comma-separated list (or Python list) of arguments, and translation for each passed argument name will be skipped. Alternatively, pass `True` and all translation will be skipped.

    Skipping tranlsation allows for arguments to be formatted directly in the format which docker-py expects. This allows for API changes and other issues to be more easily worked around. An example of using this option to skip translation would be:

        salt myminion docker.create image=centos:7.3.1611 skip_translate=environment environment="{'FOO': 'bar'}"

    See the following links for more information:

    - docker-py Low-level API

    - Docker Engine API

  ignore_collisionsFalse

    Since many of docker-py's arguments differ in name from their CLI counterparts (with which most Docker users are more familiar), Salt detects usage of these and aliases them to the docker-py version of that argument. However, if both the alias and the docker-py version of the same argument (e.g. `env` and `environment`) are used, an error will be raised. Set this argument to `True` to suppress these errors and keep the docker-py version of the argument.

  validate_ip_addrsTrue

    For parameters which accept IP addresses as input, IP address validation will be performed. To disable, set this to `False`

  client_timeout60

    Timeout in seconds for the Docker client. This is not a timeout for this function, but for receiving a response from the API.

    Note

    This is only used if Salt needs to pull the requested image.

  CONTAINER CONFIGURATION ARGUMENTS

  auto_remove (or rm)False

    Enable auto-removal of the container on daemon side when the container’s process exits (analogous to running a docker container with `--rm` on the CLI).

    Examples:

    - `auto_remove=True`

    - `rm=True`

  binds

    Files/directories to bind mount. Each bind mount should be passed in one of the following formats:

    - `<host_path>:<container_path>` - `host_path` is mounted within the container as `container_path` with read-write access.

    - `<host_path>:<container_path>:<selinux_context>` - `host_path` is mounted within the container as `container_path` with read-write access. Additionally, the specified selinux context will be set within the container.

    - `<host_path>:<container_path>:<read_only>` - `host_path` is mounted within the container as `container_path`, with the read-only or read-write setting explicitly defined.

    - `<host_path>:<container_path>:<read_only>,<selinux_context>` - `host_path` is mounted within the container as `container_path`, with the read-only or read-write setting explicitly defined. Additionally, the specified selinux context will be set within the container.

    `<read_only>` can be either `ro` for read-write access, or `ro` for read-only access. When omitted, it is assumed to be read-write.

    `<selinux_context>` can be `z` if the volume is shared between multiple containers, or `Z` if the volume should be private.

    Note

    When both `<read_only>` and `<selinux_context>` are specified, there must be a comma before `<selinux_context>`.

    Binds can be expressed as a comma-separated list or a Python list, however in cases where both ro/rw and an selinux context are specified, the binds must be specified as a Python list.

    Examples:

    - `binds=/srv/www:/var/www:ro`

    - `binds=/srv/www:/var/www:rw`

    - `binds=/srv/www:/var/www`

    - `binds="['/srv/www:/var/www:ro,Z']"`

    - `binds="['/srv/www:/var/www:rw,Z']"`

    - `binds=/srv/www:/var/www:Z`

    - `dns="['8.8.8.8', '8.8.4.4']"`

    Note

    To skip IP address validation, use `validate_ip_addrs=False`

  dns_opt

    Additional options to be added to the container’s `resolv.conf` file

    Example: `dns_opt=ndots:9`

  dns_search

    List of DNS search domains. Can be passed as a comma-separated list or a Python list.

    Examples:

    - `dns_search=foo1.domain.tld,foo2.domain.tld`

    - `dns_search="[foo1.domain.tld, foo2.domain.tld]"`

  domainname

    The domain name to use for the container

    Example: `domainname=domain.tld`

  entrypoint

    Entrypoint for the container. Either a string (e.g. `"mycmd --arg1 --arg2"`) or a Python list (e.g. `"['mycmd', '--arg1', '--arg2']"`)

    Examples:

    - `entrypoint="cat access.log"`

    - `entrypoint="['cat', 'access.log']"`

  environment (or env)

    Either a dictionary of environment variable names and their values, or a Python list of strings in the format `VARNAME=value`.

    Examples:

    - `environment='VAR1=value,VAR2=value'`

    - `environment="['VAR1=value', 'VAR2=value']"`

    - `environment="{'VAR1': 'value', 'VAR2': 'value'}"`

  extra_hosts

    Additional hosts to add to the container's /etc/hosts file. Can be passed as a comma-separated list or a Python list. Requires Docker 1.3.0 or newer.

    Examples:

    - `extra_hosts=web1:10.9.8.7,web2:10.9.8.8`

    - `extra_hosts="['web1:10.9.8.7', 'web2:10.9.8.8']"`

    - `extra_hosts="{'web1': '10.9.8.7', 'web2': '10.9.8.8'}"`

    Note

    To skip IP address validation, use `validate_ip_addrs=False`

  group_add

    List of additional group names and/or IDs that the container process will run as

    Examples:

    - `group_add=web,network`

    - `group_add="['web', 'network']"`

  hostname

    Hostname of the container. If not provided, and if a `name` has been provided, the `hostname` will default to the `name` that was passed.

    Example: `hostname=web1`

    Warning

    If the container is started with `network_mode=host`, the hostname will be overridden by the hostname of the Minion.

  interactive (or stdin_open): False

    Leave stdin open, even if not attached

    Examples:

    - `interactive=True`

    - `stdin_open=True`

  ipc_mode (or ipc)

    Set the IPC mode for the container. The default behavior is to create a private IPC namespace for the container, but this option can be used to change that behavior:

    - `container:<container_name_or_id>` reuses another container shared memory, semaphores and message queues

    - `host`: use the host's shared memory, semaphores and message queues

    Examples:

    - `ipc_mode=container:foo`

    - `ipc=host`

    Warning

    Using `host` gives the container full access to local shared memory and is therefore considered insecure.

  isolation

    Specifies the type of isolation technology used by containers

    Example: `isolation=hyperv`

    Note

    The default value on Windows server is `process`, while the default value on Windows client is `hyperv`. On Linux, only `default` is supported.

  labels (or label)

    Add metadata to the container. Labels can be set both with and without values:

    Examples:

    - `labels=foo,bar=baz`

    - `labels="['foo', 'bar=baz']"`

    Changed in version 2018.3.0: Labels both with and without values can now be mixed. Earlier releases only permitted one method or the other.

  links

    Link this container to another. Links should be specified in the format `<container_name_or_id>:<link_alias>`. Multiple links can be passed, ether as a comma separated list or a Python list.

    Examples:

    - `links=web1:link1,web2:link2`,

    - `links="['web1:link1', 'web2:link2']"`

    - `links="{'web1': 'link1', 'web2': 'link2'}"`

  log_driver

    Set container's logging driver. Requires Docker 1.6 or newer.

    Example:

    - `log_driver=syslog`

    Note

    The logging driver feature was improved in Docker 1.13 introducing option name changes. Please see Docker's Configure logging drivers documentation for more information.

  log_opt

    Config options for the `log_driver` config option. Requires Docker 1.6 or newer.

    Example:

    - `log_opt="syslog-address=tcp://192.168.0.42,syslog-facility=daemon"`

    - `log_opt="['syslog-address=tcp://192.168.0.42', 'syslog-facility=daemon']"`

    - `log_opt="{'syslog-address': 'tcp://192.168.0.42', 'syslog-facility': 'daemon'}"`

  lxc_conf

    Additional LXC configuration parameters to set before starting the container.

    Examples:

    - `lxc_conf="lxc.utsname=docker,lxc.arch=x86_64"`

    - `lxc_conf="['lxc.utsname=docker', 'lxc.arch=x86_64']"`

    - `lxc_conf="{'lxc.utsname': 'docker', 'lxc.arch': 'x86_64'}"`

    Note

    These LXC configuration parameters will only have the desired effect if the container is using the LXC execution driver, which has been deprecated for some time.

  mac_address

    MAC address to use for the container. If not specified, a random MAC address will be used.

    Example: `mac_address=01:23:45:67:89:0a`

  mem_limit (or memory)0

    Memory limit. Can be specified in bytes or using single-letter units (i.e. `512M`, `2G`, etc.). A value of `0` (the default) means no memory limit.

    Examples:

    - `mem_limit=512M`

    - `memory=1073741824`

  mem_swappiness

    Tune a container's memory swappiness behavior. Accepts an integer between 0 and 100.

    Example: `mem_swappiness=60`

  memswap_limit (or memory_swap)-1

    Total memory limit (memory plus swap). Set to `-1` to disable swap. A value of `0` means no swap limit.

    Examples:

    - `memswap_limit=1G`

    - `memory_swap=2147483648`

  network_disabledFalse

    If `True`, networking will be disabled within the container

    Example: `network_disabled=True`

  network_modebridge

    One of the following:

    - `bridge` - Creates a new network stack for the container on the docker bridge

    - `none` - No networking (equivalent of the Docker CLI argument `--net=none`). Not to be confused with Python's `None`.

    - `container:<name_or_id>` - Reuses another container's network stack

    - `host` - Use the host's network stack inside the container

      Warning

      Using `host` mode gives the container full access to the hosts system's services (such as D-Bus), and is therefore considered insecure.

    Examples:

    - `network_mode=null`

    - `network_mode=container:web1`

  oom_kill_disable

    Whether to disable OOM killer

    Example: `oom_kill_disable=False`

  oom_score_adj

    An integer value containing the score given to the container in order to tune OOM killer preferences

    Example: `oom_score_adj=500`

  pid_mode

    Set to `host` to use the host container's PID namespace within the container. Requires Docker 1.5.0 or newer.

    Example: `pid_mode=host`

  pids_limit

    Set the container's PID limit. Set to `-1` for unlimited.

    Example: `pids_limit=2000`

  port_bindings (or publish)

    Bind exposed ports which were exposed using the `ports` argument to `docker.create`. These should be passed in the same way as the `--publish` argument to the `docker run` CLI command:

    - `ip:hostPort:containerPort` - Bind a specific IP and port on the host to a specific port within the container.

    - `ip::containerPort` - Bind a specific IP and an ephemeral port to a specific port within the container.

    - `hostPort:containerPort` - Bind a specific port on all of the host's interfaces to a specific port within the container.

    - `containerPort` - Bind an ephemeral port on all of the host's interfaces to a specific port within the container.

    Multiple bindings can be separated by commas, or passed as a Python list. The below two examples are equivalent:

    - `port_bindings="5000:5000,2123:2123/udp,8080"`

    - `port_bindings="['5000:5000', '2123:2123/udp', 8080]"`

    Port bindings can also include ranges:

    - `port_bindings="14505-14506:4505-4506"`

    Note

    When specifying a protocol, it must be passed in the `containerPort` value, as seen in the examples above.

  ports

    A list of ports to expose on the container. Can be passed as comma-separated list or a Python list. If the protocol is omitted, the port will be assumed to be a TCP port.

    Examples:

    - `ports=1111,2222/udp`

    - `ports="[1111, '2222/udp']"`

  privilegedFalse

    If `True`, runs the exec process with extended privileges

    Example: `privileged=True`

  publish_all_ports (or publish_all): False

    Publish all ports to the host

    Example: `publish_all_ports=True`

  read_onlyFalse

    If `True`, mount the container’s root filesystem as read only

    Example: `read_only=True`

  restart_policy (or restart)

    Set a restart policy for the container. Must be passed as a string in the format `policy[:retry_count]` where `policy` is one of `always`, `unless-stopped`, or `on-failure`, and `retry_count` is an optional limit to the number of retries. The retry count is ignored when using the `always` or `unless-stopped` restart policy.

    Examples:

    - `restart_policy=on-failure:5`

    - `restart_policy=always`

  security_opt

    Security configuration for MLS systems such as SELinux and AppArmor. Can be passed as a comma-separated list or a Python list.

    Examples:

    - `security_opt=apparmor:unconfined,param2:value2`

    - `security_opt='["apparmor:unconfined", "param2:value2"]'`

    Important

    Some security options can contain commas. In these cases, this argument must be passed as a Python list, as splitting by comma will result in an invalid configuration.

    Note

    See the documentation for security_opt at https://docs.docker.com/engine/reference/run/#security-configuration

  shm_size

    Size of /dev/shm

    Example: `shm_size=128M`

  stop_signal

    The signal used to stop the container. The default is `SIGTERM`.

    Example: `stop_signal=SIGRTMIN+3`

  stop_timeout

    Timeout to stop the container, in seconds

    Example: `stop_timeout=5`

  storage_opt

    Storage driver options for the container

    Examples:

    - `storage_opt='dm.basesize=40G'`

    - `storage_opt="['dm.basesize=40G']"`

    - `storage_opt="{'dm.basesize': '40G'}"`

  sysctls (or sysctl)

    Set sysctl options for the container

    Examples:

    - `sysctl='fs.nr_open=1048576,kernel.pid_max=32768'`

    - `sysctls="['fs.nr_open=1048576', 'kernel.pid_max=32768']"`

    - `sysctls="{'fs.nr_open': '1048576', 'kernel.pid_max': '32768'}"`

  tmpfs

    A map of container directories which should be replaced by tmpfs mounts, and their corresponding mount options. Can be passed as Python list of PATH:VALUE mappings, or a Python dictionary. However, since commas usually appear in the values, this option cannot be passed as a comma-separated list.

    Examples:

    - `tmpfs="['/run:rw,noexec,nosuid,size=65536k', '/var/lib/mysql:rw,noexec,nosuid,size=600m']"`

    - `tmpfs="{'/run': 'rw,noexec,nosuid,size=65536k', '/var/lib/mysql': 'rw,noexec,nosuid,size=600m'}"`

  ttyFalse

    Attach TTYs

    Example: `tty=True`

  ulimits (or ulimit)

    List of ulimits. These limits should be passed in the format `<ulimit_name>:<soft_limit>:<hard_limit>`, with the hard limit being optional. Can be passed as a comma-separated list or a Python list.

    Examples:

    - `ulimits="nofile=1024:1024,nproc=60"`

    - `ulimits="['nofile=1024:1024', 'nproc=60']"`

  user

    User under which to run exec process

    Example: `user=foo`

    Sets the user namsepace mode, when the user namespace remapping option is enabled.

    Example: `userns_mode=host`

  volumes (or volume)

    List of directories to expose as volumes. Can be passed as a comma-separated list or a Python list.

    Examples:

    - `volumes=/mnt/vol1,/mnt/vol2`

    - `volume="['/mnt/vol1', '/mnt/vol2']"`

  volumes_from

    Container names or IDs from which the container will get volumes. Can be passed as a comma-separated list or a Python list.

    Example: `volumes_from=foo`, `volumes_from=foo,bar`, `volumes_from="[foo, bar]"`

  volume_driver

    Sets the container's volume driver

    Example: `volume_driver=foobar`

  working_dir (or workdir)

    Working directory inside the container

    Examples:

    - `working_dir=/var/log/nginx`

    - `workdir=/var/www/myapp`

  RETURN DATA

  A dictionary containing the following keys:

  - `Id` - ID of the newly-created container

  - `Name` - Name of the newly-created container

  CLI Example:

      # Create a data-only container
      salt myminion docker.create myuser/mycontainer volumes="/mnt/vol1,/mnt/vol2"
      # Create a CentOS 7 container that will stay running once started
      salt myminion docker.create centos:7 name=mycent7 interactive=True tty=True command=bash

salt.modules.dockermod.create_network(name, skip_translate=None, ignore_collisions=False, validate_ip_addrs=True, client_timeout=60, **kwargs)

  Changed in version 2018.3.0: Support added for network configuration options other than `driver` and `driver_opts`, as well as IPAM configuration.

  Create a new network

  Note

  This function supports all arguments for network and IPAM pool configuration which are available for the release of docker-py installed on the minion. For that reason, the arguments described below in the NETWORK CONFIGURATION ARGUMENTS and IP ADDRESS MANAGEMENT (IPAM) sections may not accurately reflect what is available on the minion. The `docker.get_client_args` function can be used to check the available arguments for the installed version of docker-py (they are found in the `network_config` and `ipam_config` sections of the return data), but Salt will not prevent a user from attempting to use an argument which is unsupported in the release of Docker which is installed. In those cases, network creation be attempted but will fail.

  name

    Network name

  skip_translate

    This function translates Salt CLI or SLS input into the format which docker-py expects. However, in the event that Salt's translation logic fails (due to potential changes in the Docker Remote API, or to bugs in the translation code), this argument can be used to exert granular control over which arguments are translated and which are not.

    Pass this argument as a comma-separated list (or Python list) of arguments, and translation for each passed argument name will be skipped. Alternatively, pass `True` and all translation will be skipped.

    Skipping tranlsation allows for arguments to be formatted directly in the format which docker-py expects. This allows for API changes and other issues to be more easily worked around. See the following links for more information:

    - docker-py Low-level API

    - Docker Engine API

    Added in version 2018.3.0.

  ignore_collisionsFalse

    Since many of docker-py's arguments differ in name from their CLI counterparts (with which most Docker users are more familiar), Salt detects usage of these and aliases them to the docker-py version of that argument. However, if both the alias and the docker-py version of the same argument (e.g. `options` and `driver_opts`) are used, an error will be raised. Set this argument to `True` to suppress these errors and keep the docker-py version of the argument.

    Added in version 2018.3.0.

  validate_ip_addrsTrue

    For parameters which accept IP addresses as input, IP address validation will be performed. To disable, set this to `False`

    Note

    When validating subnets, whether or not the IP portion of the subnet is a valid subnet boundary will not be checked. The IP will portion will be validated, and the subnet size will be checked to confirm it is a valid number (1-32 for IPv4, 1-128 for IPv6).

    Added in version 2018.3.0.

  NETWORK CONFIGURATION ARGUMENTS

  driver

    Network driver

    Example: `driver=macvlan`

  driver_opts (or driver_opt, or options)

    Options for the network driver. Either a dictionary of option names and values or a Python list of strings in the format `varname=value`.

    Examples:

    - `driver_opts='macvlan_mode=bridge,parent=eth0'`

    - `driver_opts="['macvlan_mode=bridge', 'parent=eth0']"`

    - `driver_opts="{'macvlan_mode': 'bridge', 'parent': 'eth0'}"`

  check_duplicateTrue

    If `True`, checks for networks with duplicate names. Since networks are primarily keyed based on a random ID and not on the name, and network name is strictly a user-friendly alias to the network which is uniquely identified using ID, there is no guaranteed way to check for duplicates. This option providess a best effort, checking for any networks which have the same name, but it is not guaranteed to catch all name collisions.

    Example: `check_duplicate=False`

  internalFalse

    If `True`, restricts external access to the network

    Example: `internal=True`

  labels

    Add metadata to the network. Labels can be set both with and without values:

    Examples (with values):

    - `labels="label1=value1,label2=value2"`

    - `labels="['label1=value1', 'label2=value2']"`

    - `labels="{'label1': 'value1', 'label2': 'value2'}"`

    Examples (without values):

    - `labels=label1,label2`

    - `labels="['label1', 'label2']"`

  enable_ipv6 (or ipv6)False

    Enable IPv6 on the network

    Example: `enable_ipv6=True`

    Note

    While it should go without saying, this argument must be set to `True` to configure an IPv6 subnet. Also, if this option is turned on without an IPv6 subnet explicitly configured, you will get an error unless you have set up a fixed IPv6 subnet. Consult the Docker IPv6 docs for information on how to do this.

  attachableFalse

    If `True`, and the network is in the global scope, non-service containers on worker nodes will be able to connect to the network.

    Example: `attachable=True`

    Note

    While support for this option was added in API version 1.24, its value was not added to the inpsect results until API version 1.26. The version of Docker which is available for CentOS 7 runs API version 1.24, meaning that while Salt can pass this argument to the API, it has no way of knowing the value of this config option in an existing Docker network.

  scope

    Specify the network's scope (`local`, `global` or `swarm`)

    Example: `scope=local`

  ingressFalse

    If `True`, create an ingress network which provides the routing-mesh in swarm mode

    Example: `ingress=True`

  IP ADDRESS MANAGEMENT (IPAM)

  This function supports networks with either IPv4, or both IPv4 and IPv6. If configuring IPv4, then you can pass the IPAM arguments as shown below, as individual arguments on the Salt CLI. However, if configuring IPv4 and IPv6, the arguments must be passed as a list of dictionaries, in the `ipam_pools` argument. See the CLI Examples below. These docs also have more information on these arguments.

  IPAM ARGUMENTS

  ipam_driver

    IPAM driver to use, if different from the default one

    Example: `ipam_driver=foo`

  ipam_opts

    Options for the IPAM driver. Either a dictionary of option names and values or a Python list of strings in the format `varname=value`.

    Examples:

    - `ipam_opts='foo=bar,baz=qux'`

    - `ipam_opts="['foo=bar', 'baz=quz']"`

    - `ipam_opts="{'foo': 'bar', 'baz': 'qux'}"`

  IPAM POOL ARGUMENTS

  subnet

    Subnet in CIDR format that represents a network segment

    Example: `subnet=192.168.50.0/25`

  iprange (or ip_range)

    Allocate container IP from a sub-range within the subnet

    Subnet in CIDR format that represents a network segment

    Example: `iprange=192.168.50.64/26`

  gateway

    IPv4 gateway for the master subnet

    Example: `gateway=192.168.50.1`

  aux_addresses (or aux_address)

    A dictionary of mapping container names to IP addresses which should be allocated for them should they connect to the network. Either a dictionary of option names and values or a Python list of strings in the format `host=ipaddr`.

    Examples:

    - `aux_addresses='foo.bar.tld=192.168.50.10,hello.world.tld=192.168.50.11'`

    - `aux_addresses="['foo.bar.tld=192.168.50.10', 'hello.world.tld=192.168.50.11']"`

    - `aux_addresses="{'foo.bar.tld': '192.168.50.10', 'hello.world.tld': '192.168.50.11'}"`

  CLI Examples:

      salt myminion docker.create_network web_network driver=bridge
      # IPv4
      salt myminion docker.create_network macvlan_network driver=macvlan driver_opts="{'parent':'eth0'}" gateway=172.20.0.1 subnet=172.20.0.0/24
      # IPv4 and IPv6
      salt myminion docker.create_network mynet ipam_pools='[{"subnet": "10.0.0.0/24", "gateway": "10.0.0.1"}, {"subnet": "fe3f:2180:26:1::60/123", "gateway": "fe3f:2180:26:1::61"}]'

salt.modules.dockermod.dangling(prune=False, force=False)

  Return top-level images (those on which no other images depend) which do not have a tag assigned to them. These include:

  - Images which were once tagged but were later untagged, such as those which were superseded by committing a new copy of an existing tagged image.

  - Images which were loaded using `docker.load` (or the `docker load` Docker CLI command), but not tagged.

  pruneFalse

    Remove these images

  forceFalse

    If `True`, and if `prune=True`, then forcibly remove these images.

  RETURN DATA

  If `prune=False`, the return data will be a list of dangling image IDs.

  If `prune=True`, the return data will be a dictionary with each key being the ID of the dangling image, and the following information for each image:

  - `Comment` - Any error encountered when trying to prune a dangling image

    (Only present if prune failed)

  - `Removed` - A boolean (`True` if prune was successful, `False` if not)

      salt myminion docker.dangling prune=True

salt.modules.dockermod.depends(name)

  Returns the containers and images, if any, which depend on the given image

  name

    Name or ID of image

  RETURN DATA

  A dictionary containing the following keys:

  - `Containers` - A list of containers which depend on the specified image

  - `Images` - A list of IDs of images which depend on the specified image

  - `Added` - A list of paths that were added.

  - `Changed` - A list of paths that were changed.

  - `Deleted` - A list of paths that were deleted.

  These keys will only be present if there were changes, so if the container has no differences the return dict will be empty.

  CLI Example:

      salt myminion docker.diff mycontainer

salt.modules.dockermod.disconnect_all_containers_from_network(network_id)

  Added in version 2018.3.0.

  A boolean (`True` if the container exists, otherwise `False`)

  CLI Example:

      salt myminion docker.exists mycontainer

salt.modules.dockermod.export(name, path, overwrite=False, makedirs=False, compression=None, **kwargs)

  Exports a container to a tar archive. It can also optionally compress that tar archive, and push it up to the Master.

  name

    Container name or ID

  path

    Absolute path on the Minion where the container will be exported

  overwriteFalse

    Unless this option is set to `True`, then if a file exists at the location specified by the `path` argument, an error will be raised.

  makedirsFalse

    If `True`, then if the parent directory of the file specified by the `path` argument does not exist, Salt will attempt to create it.

  compressionNone

    Can be set to any of the following:

    - `gzip` or `gz` for gzip compression

    - `bzip2` or `bz2` for bzip2 compression

    - `xz` or `lzma` for XZ compression (requires xz-utils, as well as the `lzma` module from Python 3.3, available in Python 2 and Python 3.0-3.2 as backports.lzma)

    This parameter can be omitted and Salt will attempt to determine the compression type by examining the filename passed in the `path` parameter.

  pushFalse

    If `True`, the container will be pushed to the master using `cp.push`.

    Note

    This requires `file_recv` to be set to `True` on the Master.

  RETURN DATA

  A dictionary will containing the following keys:

  - `Path` - Path of the file that was exported

  - `Push` - Reports whether or not the file was successfully pushed to the Master

    (Only present if push=True)

  - `Size` - Size of the file, in bytes

  - `Size_Human` - Size of the file, in human-readable units

  - `Time_Elapsed` - Time in seconds taken to perform the export

  CLI Examples:

salt.modules.dockermod.get_client_args(limit=None)

  Added in version 2016.3.6,2016.11.4,2017.7.0.

  Changed in version 2017.7.0: Replaced the container config args with the ones from the API's `create_container` function.

  Changed in version 2018.3.0: Added ability to limit the input to specific client functions

  Many functions in Salt have been written to support the full list of arguments for a given function in the docker-py Low-level API. However, depending on the version of docker-py installed on the minion, the available arguments may differ. This function will get the arguments for various functions in the installed version of docker-py, to be used as a reference.

  limit

    An optional list of categories for which to limit the return. This is useful if only a specific set of arguments is desired, and also keeps other function's argspecs from needlessly being examined.

  AVAILABLE LIMITS

  - `create_container` - arguments accepted by create_container() (used by `docker.create`)

  - `host_config` - arguments accepted by create_host_config() (used to build the host config for `docker.create`)

  - `connect_container_to_network` - arguments used by connect_container_to_network() to construct an endpoint config when connecting to a network (used by `docker.connect_container_to_network`)

  - `create_network` - arguments accepted by create_network() (used by `docker.create_network`)

  - `ipam_config` - arguments used to create an IPAM pool (used by `docker.create_network` in the process of constructing an IPAM config dictionary)

  CLI Example:

      salt myminion docker.get_client_args
      salt myminion docker.get_client_args logs
      salt myminion docker.get_client_args create_container,connect_container_to_network

    New name to assign to container

  CLI Example:

      salt myminion docker.rename foo bar

salt.modules.dockermod.resolve_image_id(name)

  Added in version 2018.3.0.

  Given an image name (or partial image ID), return the full image ID. If no match is found among the locally-pulled images, then `False` will be returned.

  CLI Examples:

      salt myminion docker.resolve_image_id foo
      salt myminion docker.resolve_image_id foo:bar
      salt myminion docker.resolve_image_id 36540f359ca3

salt.modules.dockermod.resolve_tag(name, **kwargs)

  Added in version 2017.7.2.

  Changed in version 2018.3.0: Instead of matching against pulled tags using `docker.list_tags`, this function now simply inspects the passed image name using `docker.inspect_image` and returns the first matching tag. If no matching tags are found, it is assumed that the passed image is an untagged image ID, and the full ID is returned.

  Inspects the specified image name and returns the first matching tag in the inspect results. If the specified image is not pulled locally, this function will return `False`.

  name

    Image name to resolve. If the image is found but there are no tags, this means that the image name passed was an untagged image. In this case the image ID will be returned.

  allFalse

    If `True`, a list of all matching tags will be returned. If the image is found but there are no tags, then a list will still be returned, but it will simply contain the image ID.

    Added in version 2018.3.0.

  tags

    Deprecated since version 2018.3.0.

  CLI Examples:

      salt myminion docker.resolve_tag busybox
      salt myminion docker.resolve_tag centos:7 all=True
      salt myminion docker.resolve_tag c9f378ac27d9

salt.modules.dockermod.restart(name, timeout=10)

  Restarts a container

  name

    Container name or ID

  timeout10

    Timeout in seconds after which the container will be killed (if it has not yet gracefully shut down)

  RETURN DATA

  A dictionary will be returned, containing the following keys:

  - `status` - A dictionary showing the prior state of the container as well as the new state

  - `result` - A boolean noting whether or not the action was successful

  - `restarted` - If restart was successful, this key will be present and will be set to `True`.

  CLI Examples:

      salt myminion docker.restart mycontainer
      salt myminion docker.restart mycontainer timeout=20

salt.modules.dockermod.retcode(name, cmd, exec_driver=None, stdin=None, python_shell=True, output_loglevel='debug', use_vt=False, ignore_retcode=False, keep_env=None)

  use_vtFalse

    Use SaltStack's utils.vt to stream output to console.

  keep_envNone

    If not passed, only a sane default PATH environment variable will be set. If `True`, all environment variables from the container's host will be kept. Otherwise, a comma-separated list (or Python list) of environment variable names can be passed, and those environment variables will be kept.

  CLI Example:

      salt myminion docker.retcode mycontainer 'ls -l /etc'

salt.modules.dockermod.rm_(name, force=False, volumes=False, **kwargs)

  Removes a container

  name

    Container name or ID

  forceFalse

    If `True`, the container will be killed first before removal, as the Docker API will not permit a running container to be removed. This option is set to `False` by default to prevent accidental removal of a running container.

  stopFalse

    If `True`, the container will be stopped first before removal, as the Docker API will not permit a running container to be removed. This option is set to `False` by default to prevent accidental removal of a running container.

    Added in version 2017.7.0.

  timeout

    Optional timeout to be passed to `docker.stop` if stopping the container.

    Added in version 2018.3.0.

  - `Layers` - A list of the IDs of image layers that were removed

  - `Tags` - A list of the tags that were removed

  - `Errors` - A list of any errors that were encountered

  CLI Examples:

  Run `cmd.run` within a container

  name

    Container name or ID in which to run the command

  cmd

    Command to run

  exec_driverNone

    If not passed, the execution driver will be detected as described above.

  stdinNone

    Standard input to be used for the command

  output_logleveldebug

    Level at which to log the output from the command. Set to `quiet` to suppress logging.

  use_vtFalse

    Use SaltStack's utils.vt to stream output to console.

  keep_envNone

    If not passed, only a sane default PATH environment variable will be set. If `True`, all environment variables from the container's host will be kept. Otherwise, a comma-separated list (or Python list) of environment variable names can be passed, and those environment variables will be kept.

  CLI Example:

      salt myminion docker.run mycontainer 'ls -l /etc'

salt.modules.dockermod.run_all(name, cmd, exec_driver=None, stdin=None, python_shell=True, output_loglevel='debug', use_vt=False, ignore_retcode=False, keep_env=None)

  Run `cmd.run_all` within a container

  Note

  While the command is run within the container, it is initiated from the host. Therefore, the PID in the return dict is from the host, not from the container.

  name

    Container name or ID in which to run the command

  cmd

    Command to run

  exec_driverNone

    If not passed, the execution driver will be detected as described above.

  stdinNone

    Standard input to be used for the command

  output_logleveldebug

    Level at which to log the output from the command. Set to `quiet` to suppress logging.

  use_vtFalse

    Use SaltStack's utils.vt to stream output to console.

  keep_envNone

    If not passed, only a sane default PATH environment variable will be set. If `True`, all environment variables from the container's host will be kept. Otherwise, a comma-separated list (or Python list) of environment variable names can be passed, and those environment variables will be kept.

  CLI Example:

      salt myminion docker.run_all mycontainer 'ls -l /etc'

salt.modules.dockermod.run_container(image, name=None, skip_translate=None, ignore_collisions=False, validate_ip_addrs=True, client_timeout=60, bg=False, replace=False, force=False, networks=None, **kwargs)

  Added in version 2018.3.0.

  Equivalent to `docker run` on the Docker CLI. Runs the container, waits for it to exit, and returns the container's logs when complete.

  Note

  Not to be confused with `docker.run`, which provides a `cmd.run`-like interface for executing commands in a running container.

  This function accepts the same arguments as `docker.create`, with the exception of `start`. In addition, it accepts the arguments from `docker.logs`, with the exception of `follow`, to control how logs are returned. Finally, the `bg` argument described below can be used to optionally run the container in the background (the default behavior is to block until the container exits).

  bgFalse

    If `True`, this function will not wait for the container to exit and will not return its logs. It will however return the container's name and ID, allowing for `docker.logs` to be used to view the logs.

    Note

    The logs will be inaccessible once the container exits if `auto_remove` is set to `True`, so keep this in mind.

  replaceFalse

    If `True`, and if the named container already exists, this will remove the existing container. The default behavior is to return a `False` result when the container already exists.

  forceFalse

    If `True`, and the named container already exists, and `replace` is also set to `True`, then the container will be forcibly removed. Otherwise, the state will not proceed and will return a `False` result.

  networks

    Networks to which the container should be connected. If automatic IP configuration is being used, the networks can be a simple list of network names. If custom IP configuration is being used, then this argument must be passed as a dictionary.

  CLI Examples:

      salt myminion docker.run_container myuser/myimage command=/usr/local/bin/myscript.sh
      # Run container in the background
      salt myminion docker.run_container myuser/myimage command=/usr/local/bin/myscript.sh bg=True
      # Connecting to two networks using automatic IP configuration
      salt myminion docker.run_container myuser/myimage command='perl /scripts/sync.py' networks=net1,net2
      # net1 using automatic IP, net2 using static IPv4 address
      salt myminion docker.run_container myuser/myimage command='perl /scripts/sync.py' networks='{"net1": {}, "net2": {"ipv4_address": "192.168.27.12"}}'

  name

    Container name or ID in which to run the command

  cmd

    Command to run

  exec_driverNone

    If not passed, the execution driver will be detected as described above.

  stdinNone

    Standard input to be used for the command

  output_logleveldebug

    Level at which to log the output from the command. Set to `quiet` to suppress logging.

  use_vtFalse

    Use SaltStack's utils.vt to stream output to console.

  keep_envNone

    If not passed, only a sane default PATH environment variable will be set. If `True`, all environment variables from the container's host will be kept. Otherwise, a comma-separated list (or Python list) of environment variable names can be passed, and those environment variables will be kept.

  CLI Example:

      salt myminion docker.run_stderr mycontainer 'ls -l /etc'

salt.modules.dockermod.run_stdout(name, cmd, exec_driver=None, stdin=None, python_shell=True, output_loglevel='debug', use_vt=False, ignore_retcode=False, keep_env=None)

  Run `cmd.run_stdout` within a container

  name

    Container name or ID in which to run the command

  cmd

    Command to run

  exec_driverNone

    If not passed, the execution driver will be detected as described above.

  stdinNone

    Standard input to be used for the command

  output_logleveldebug

    Level at which to log the output from the command. Set to `quiet` to suppress logging.

  use_vtFalse

    Use SaltStack's utils.vt to stream output to console.

salt.modules.dockermod.save(name, path, overwrite=False, makedirs=False, compression=None, **kwargs)

  Saves an image and to a file on the minion. Equivalent to running the `docker save` Docker CLI command, but unlike `docker save` this will also work on named images instead of just images IDs.

  name

    Name or ID of image. Specify a specific tag by using the `repo:tag` notation.

  path

    Absolute path on the Minion where the image will be exported

  overwriteFalse

    Unless this option is set to `True`, then if the destination file exists an error will be raised.

  makedirsFalse

    If `True`, then if the parent directory of the file specified by the `path` argument does not exist, Salt will attempt to create it.

  compressionNone

    Can be set to any of the following:

    - `gzip` or `gz` for gzip compression

    - `bzip2` or `bz2` for bzip2 compression

    - `xz` or `lzma` for XZ compression (requires xz-utils, as well as the `lzma` module from Python 3.3, available in Python 2 and Python 3.0-3.2 as backports.lzma)

    This parameter can be omitted and Salt will attempt to determine the compression type by examining the filename passed in the `path` parameter.

    Note

    Since the Docker API does not support `docker save`, compression will be a bit slower with this function than with `docker.export` since the image(s) will first be saved and then the compression done afterwards.

  pushFalse

    If `True`, the container will be pushed to the master using `cp.push`.

    Note

    This requires `file_recv` to be set to `True` on the Master.

  RETURN DATA

  A dictionary will be returned, containing the following keys:

  - `Path` - Path of the file that was saved

  - `Push` - Reports whether or not the file was successfully pushed to the Master

    (Only present if push=True)

  - `Size` - Size of the file, in bytes

  - `Size_Human` - Size of the file, in human-readable units

  - `Time_Elapsed` - Time in seconds taken to perform the save

  CLI Examples:

      salt myminion docker.save centos:7 /tmp/cent7.tar
      salt myminion docker.save 0123456789ab cdef01234567 /tmp/saved.tar

  use_vtFalse

    Use SaltStack's utils.vt to stream output to console.

  keep_envNone

    If not passed, only a sane default PATH environment variable will be set. If `True`, all environment variables from the container's host will be kept. Otherwise, a comma-separated list (or Python list) of environment variable names can be passed, and those environment variables will be kept.

  CLI Example:
