community.docker.docker_volume – Manage Docker volumes

Note

This plugin is part of the community.docker collection (version 1.10.2).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.docker.

To use it in a playbook, specify: community.docker.docker_volume.

Synopsis 

Create/remove Docker volumes.
Performs largely the same function as the “docker volume” CLI subcommand.

Requirements 

The below requirements are needed on the host that executes this module.

Docker SDK for Python: Please note that the docker-py Python module has been superseded by docker (see here for details). For Python 2.6, docker-py must be used. Otherwise, it is recommended to install the docker Python module. Note that both modules should not be installed at the same time. Also note that when both modules are installed and one of them is uninstalled, the other might no longer function and a reinstall of it is required.
Docker SDK for Python >= 1.10.0 (use docker-py for Python 2.6)
The docker server >= 1.9.0

Parameters 

Parameter	Comments
api_version aliases: docker_api_version string	The version of the Docker API running on the Docker Host. Defaults to the latest version of the API supported by Docker SDK for Python and the docker daemon. If the value is not specified in the task, the value of environment variable `DOCKER_API_VERSION` will be used instead. If the environment variable is not set, the default value will be used. Default: “auto”
ca_cert aliases: tls_ca_cert, cacert_path path	Use a CA certificate when performing server verification by providing the path to a CA certificate file. If the value is not specified in the task and the environment variable `DOCKER_CERT_PATH` is set, the file `ca.pem` from the directory specified in the environment variable `DOCKER_CERT_PATH` will be used.
client_cert aliases: tls_client_cert, cert_path path	Path to the client’s TLS certificate file. If the value is not specified in the task and the environment variable `DOCKER_CERT_PATH` is set, the file `cert.pem` from the directory specified in the environment variable `DOCKER_CERT_PATH` will be used.
client_key aliases: tls_client_key, key_path path	Path to the client’s TLS key file. If the value is not specified in the task and the environment variable `DOCKER_CERT_PATH` is set, the file `key.pem` from the directory specified in the environment variable `DOCKER_CERT_PATH` will be used.
debug boolean	Debug mode Choices: no ← (default) yes
docker_host aliases: docker_url string	The URL or Unix socket path used to connect to the Docker API. To connect to a remote host, provide the TCP connection string. For example, `tcp://192.0.2.23:2376`. If TLS is used to encrypt the connection, the module will automatically replace `tcp` in the connection URL with `https`. If the value is not specified in the task, the value of environment variable `DOCKER_HOST` will be used instead. If the environment variable is not set, the default value will be used. Default: “unix://var/run/docker.sock”
driver string	Specify the type of volume. Docker provides the `local` driver, but 3rd party drivers can also be used. Default: “local”
driver_options dictionary	Dictionary of volume settings. Consult docker docs for valid options and values: https://docs.docker.com/engine/reference/commandline/volume_create/#driver-specific-options
labels dictionary	Dictionary of label key/values to set for the volume
recreate string	Controls when a volume will be recreated when state is `present`. Please note that recreating an existing volume will cause any data in the existing volume to be lost! The volume will be deleted and a new volume with the same name will be created. The value `always` forces the volume to be always recreated. The value `never` makes sure the volume will not be recreated. The value `options-changed` makes sure the volume will be recreated if the volume already exist and the driver, driver options or labels differ. Choices: always never ← (default) options-changed
ssl_version string	Provide a valid SSL version number. Default value determined by ssl.py module. If the value is not specified in the task, the value of environment variable `DOCKER_SSL_VERSION` will be used instead.
state string	`absent` deletes the volume. `present` creates the volume, if it does not already exist. Choices: absent present ← (default)
timeout integer	The maximum amount of time in seconds to wait on a response from the API. If the value is not specified in the task, the value of environment variable `DOCKER_TIMEOUT` will be used instead. If the environment variable is not set, the default value will be used. Default: 60
tls boolean	Secure the connection to the API by using TLS without verifying the authenticity of the Docker host server. Note that if validate_certs is set to `yes` as well, it will take precedence. If the value is not specified in the task, the value of environment variable `DOCKER_TLS` will be used instead. If the environment variable is not set, the default value will be used. Choices: no ← (default) yes
tls_hostname string	When verifying the authenticity of the Docker Host server, provide the expected name of the server. If the value is not specified in the task, the value of environment variable `DOCKER_TLS_HOSTNAME` will be used instead. If the environment variable is not set, the default value will be used. The current default value is `localhost`. This default is deprecated and will change in community.docker 2.0.0 to be a value computed from docker_host. Explicitly specify `localhost` to make sure this value will still be used, and to disable the deprecation message which will be shown otherwise.
use_ssh_client boolean added in 1.5.0 of community.docker	For SSH transports, use the `ssh` CLI tool instead of paramiko. Requires Docker SDK for Python 4.4.0 or newer. Choices: no ← (default) yes
validate_certs aliases: tls_verify boolean	Secure the connection to the API by using TLS and verifying the authenticity of the Docker host server. If the value is not specified in the task, the value of environment variable `DOCKER_TLS_VERIFY` will be used instead. If the environment variable is not set, the default value will be used. Choices: no ← (default) yes
volume_name aliases: name string / required	Name of the volume to operate on.

Notes 

Note

Connect to the Docker daemon by providing parameters with each task or by defining environment variables. You can define DOCKER_HOST, DOCKER_TLS_HOSTNAME, DOCKER_API_VERSION, DOCKER_CERT_PATH, DOCKER_SSL_VERSION, DOCKER_TLS, DOCKER_TLS_VERIFY and DOCKER_TIMEOUT. If you are using docker machine, run the script shipped with the product that sets up the environment. It will set these variables for you. See https://docs.docker.com/machine/reference/env/ for more details.
When connecting to Docker daemon with TLS, you might need to install additional Python packages. For the Docker SDK for Python, version 2.4 or newer, this can be done by installing docker[tls] with ansible.builtin.pip.
Note that the Docker SDK for Python only allows to specify the path to the Docker configuration for very few functions. In general, it will use $HOME/.docker/config.json if the DOCKER_CONFIG environment variable is not specified, and use $DOCKER_CONFIG/config.json otherwise.
This module uses the Docker SDK for Python to communicate with the Docker daemon.
