community.docker.docker_secret module – Manage docker secrets.

Note

This module is part of the community.docker collection (version 3.13.1).

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. You need further requirements to be able to use this module, see Requirements for details.

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

Synopsis 

Create and remove Docker secrets in a Swarm environment. Similar to docker secret create and docker secret rm.
Adds to the metadata of new secrets ansible_key, an encrypted hash representation of the data, which is then used in future runs to test if a secret has changed. If ansible_key is not present, then a secret will not be updated unless the force option is set.
Updates to secrets are performed by removing the secret and creating it again.

Requirements 

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

Docker API >= 1.25
Docker SDK for Python: Please note that the docker-py Python module has been superseded by docker (see here for details). This module does *not* work with docker-py.
Docker SDK for Python >= 2.1.0
Python >= 2.7

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_path aliases: ca_cert, 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. This option was called `ca_cert` and got renamed to `ca_path` in community.docker 3.6.0. The old name has been added as an alias and can still 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.
data string	The value of the secret. Mutually exclusive with `data_src`. One of `data` and `data_src` is required if `state=present`.
data_is_b64 boolean	If set to `true`, the data is assumed to be Base64 encoded and will be decoded before being used. To use binary `data`, it is better to keep it Base64 encoded and let it be decoded by this option. Choices: `false` ← (default) `true`
data_src path added in community.docker 1.10.0	The file on the target from which to read the secret. Mutually exclusive with `data`. One of `data` and `data_src` is required if `state=present`.
debug boolean	Debug mode Choices: `false` ← (default) `true`
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"`
force boolean	Use with `state=present` to always remove and recreate an existing secret. If `true`, an existing secret will be replaced, even if it has not changed. Choices: `false` ← (default) `true`
labels dictionary	A map of key:value meta data, where both key and value are expected to be strings. If new meta data is provided, or existing meta data is modified, the secret will be updated by removing it and creating it again.
name string / required	The name of the secret.
rolling_versions boolean added in community.docker 2.2.0	If set to `true`, secrets are created with an increasing version number appended to their name. Adds a label containing the version number to the managed secrets with the name `ansible_version`. Choices: `false` ← (default) `true`
ssl_version string	Provide a valid SSL version number. Default value determined by SSL Python module. If the value is not specified in the task, the value of environment variable `DOCKER_SSL_VERSION` will be used instead. Note: this option is no longer supported for Docker SDK for Python 7.0.0+. Specifying it with Docker SDK for Python 7.0.0 or newer will lead to an error.
state string	Set to `present`, if the secret should exist, and `absent`, if it should not. 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 `true` 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: `false` ← (default) `true`
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. Note that this option had a default value `localhost` in older versions. It was removed in community.docker 3.0.0. Note: this option is no longer supported for Docker SDK for Python 7.0.0+. Specifying it with Docker SDK for Python 7.0.0 or newer will lead to an error.
use_ssh_client boolean added in community.docker 1.5.0	For SSH transports, use the `ssh` CLI tool instead of paramiko. Requires Docker SDK for Python 4.4.0 or newer. Choices: `false` ← (default) `true`
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: `false` ← (default) `true`
versions_to_keep integer added in community.docker 2.2.0	When using `rolling_versions`, the number of old versions of the secret to keep. Extraneous old secrets are deleted after the new one is created. Set to `-1` to keep everything or to `0` or `1` to keep only the current one. Default: `5`

Attributes 

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.
