      version: 3.8.1

Description

Create and remove Docker secrets in a Swarm environment. Similar to C(docker secret create) and C(docker secret rm).

Adds to the metadata of new secrets C(ansible_key), an encrypted hash representation of the data, which is then used in future runs to test if a secret has changed. If C(ansible_key) is not present, then a secret will not be updated unless the O(force) option is set.

Updates to secrets are performed by removing the secret and creating it again.


Requirements

Usage examples

  • Success
    Steampunk Spotter scan finished with no errors, warnings or hints.

- name: Create secret foo (from a file on the control machine)
  community.docker.docker_secret:
    name: foo
    # If the file is JSON or binary, Ansible might modify it (because
    # it is first decoded and later re-encoded). Base64-encoding the
    # file directly after reading it prevents this to happen.
    data: "{{ lookup('file', '/path/to/secret/file') | b64encode }}"

Inputs

    default: false
    description:
    - Secure the connection to the API by using TLS without verifying the authenticity

      it will take precedence.
    - If the value is not specified in the task, the value of environment variable E(DOCKER_TLS)
      will be used instead. If the environment variable is not set, the default value
      will be used.
    type: bool

    type: str

name:
    description:
    - The name of the secret.
    required: true
    type: str

    type: str

labels:
    description:
    - A map of key:value meta data, where both key and value are expected to be strings.
