docker_secret - Manage docker secrets.

New in version 2.4.

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-py >= 2.1.0
  • Docker API >= 1.25

Parameters

Parameter Choices/Defaults Comments
api_version Default:
default provided by docker-py
The version of the Docker API running on the Docker Host. Defaults to the latest version of the API supported by docker-py.

aliases: docker_api_version
cacert_path Default:
None
Use a CA certificate when performing server verification by providing the path to a CA certificate file.

aliases: tls_ca_cert
cert_path Default:
None
Path to the client's TLS certificate file.

aliases: tls_client_cert
data
String. The value of the secret. Required when state is present.
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'.

aliases: docker_url
force Default:
no
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.
key_path Default:
None
Path to the client's TLS key file.

aliases: tls_client_key
labels
A map of key:value meta data, where both the key and value are expected to be a string.
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
required
The name of the secret.
ssl_version Default:
1.0
Provide a valid SSL version number. Default value determined by docker-py, currently 1.0.
state
    Choices:
  • absent
  • present ←
Set to present, if the secret should exist, and absent, if it should not.
timeout Default:
60
The maximum amount of time in seconds to wait on a response from the API.
tls Default:
no
Secure the connection to the API by using TLS without verifying the authenticity of the Docker host server.
tls_hostname Default:
localhost
When verifying the authenticity of the Docker Host server, provide the expected name of the server.
tls_verify Default:
no
Secure the connection to the API by using TLS and verifying the authenticity of the Docker host server.

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 secret foo
  docker_secret:
    name: foo
    data: Hello World!
    state: present

- name: Change the secret data
  docker_secret:
    name: foo
    data: Goodnight everyone!
    labels:
      bar: baz
      one: '1'
    state: present

- name: Add a new label
  docker_secret:
    name: foo
    data: Goodnight everyone!
    labels:
      bar: baz
      one: '1'
      # Adding a new label will cause a remove/create of the secret
      two: '2'
    state: present

- name: No change
  docker_secret:
    name: foo
    data: Goodnight everyone!
    labels:
      bar: baz
      one: '1'
      # Even though 'two' is missing, there is no change to the existing secret
    state: present

- name: Update an existing label
  docker_secret:
    name: foo
    data: Goodnight everyone!
    labels:
      bar: monkey   # Changing a label will cause a remove/create of the secret
      one: '1'
    state: present

- name: Force the removal/creation of the secret
  docker_secret:
    name: foo
    data: Goodnight everyone!
    force: yes
    state: present

- name: Remove secret foo
  docker_secret:
    name: foo
    state: absent
