docker_volume - Manage Docker volumes
New in version 2.4.
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.
- python >= 2.6
- docker-py >= 1.10.0
- Please note that the docker-py Python module has been superseded by docker (see here for details).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 thedocker
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. - The docker server >= 1.9.0
Parameters
Parameter | Choices/Defaults | Comments |
---|---|---|
api_version | Default: "auto" | The version of the Docker API running on the Docker Host. Defaults to the latest version of the API supported by docker-py. 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.aliases: docker_api_version |
cacert_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.aliases: tls_ca_cert | |
cert_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.aliases: tls_client_cert | |
debug bool |
| Debug mode |
docker_host | Default: "unix://var/run/docker.sock" | 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.aliases: docker_url |
driver | Default: "local" | Specify the type of volume. Docker provides the local driver, but 3rd party drivers can also be used. |
driver_options | Dictionary of volume settings. Consult docker docs for valid options and values: https://docs.docker.com/engine/reference/commandline/volume_create/#driver-specific-options
| |
force bool |
| With state present causes the volume to be deleted and recreated if the volume already exist and the driver, driver options or labels differ. This will cause any data in the existing volume to be lost. |
key_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.aliases: tls_client_key | |
labels | List of labels to set for the volume | |
name required | Name of the volume to operate on. aliases: volume_name | |
ssl_version | 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 |
| absent deletes the volume.present creates the volume, if it does not already exist. |
timeout | Default: 60 | 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. |
tls bool |
| Secure the connection to the API by using TLS without verifying the authenticity of the Docker host server. 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. |
tls_hostname | Default: "localhost" | 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. |
tls_verify bool |
| 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. |
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://docker-py.readthedocs.org/en/stable/machine/ for more details.
Examples
- name: Create a volume docker_volume: name: volume_one - name: Remove a volume docker_volume: name: volume_one state: absent - name: Create a volume with options docker_volume: name: volume_two driver_options: type: btrfs device: /dev/sda2
