community.docker.docker_stack_info module – Return information on all docker stacks

Note

This module is part of the community.docker collection (version 3.10.3).

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_stack_info.

Synopsis

  • Retrieve information on docker stacks using the docker stack command on the target node (see examples).

Requirements

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

  • Docker CLI tool docker

Parameters

Parameter

Comments

api_version

aliases: docker_api_version

string

added in community.docker 3.6.0

The version of the Docker API running on the Docker Host.

Defaults to the latest version of the API supported by this collection 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

added in community.docker 3.6.0

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.

cli_context

string

added in community.docker 3.6.0

The Docker CLI context to use.

client_cert

aliases: tls_client_cert, cert_path

path

added in community.docker 3.6.0

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

added in community.docker 3.6.0

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.

docker_cli

path

added in community.docker 3.6.0

Path to the Docker CLI. If not provided, will search for Docker CLI on the PATH.

docker_host

aliases: docker_url

string

added in community.docker 3.6.0

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"

tls

boolean

added in community.docker 3.6.0

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

added in community.docker 3.6.0

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.

validate_certs

aliases: tls_verify

boolean

added in community.docker 3.6.0

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
