community.docker.docker_secret – Manage docker secrets.¶
Note
This plugin is part of the community.docker collection (version 1.2.2).
To install it use: ansible-galaxy collection install community.docker.
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 createanddocker 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Docker SDK for Python: Please note that the docker-py Python module has been superseded by docker (see here for details).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¶
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_VERIFYandDOCKER_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
$HOME/.docker/config.jsonif theDOCKER_CONFIGenvironment variable is not specified, and use$DOCKER_CONFIG/config.jsonotherwise.This module uses the Docker SDK for Python to communicate with the Docker daemon.
Examples¶
- 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 }}"
data_is_b64: true
state: present
- name: Change the secret data
community.docker.docker_secret:
name: foo
data: Goodnight everyone!
labels:
bar: baz
one: '1'
state: present
- name: Add a new label
community.docker.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
community.docker.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
community.docker.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
community.docker.docker_secret:
name: foo
data: Goodnight everyone!
force: yes
state: present
- name: Remove secret foo
community.docker.docker_secret:
name: foo
state: absent
