community.docker.docker_network_info module – Retrieves facts about docker network
Note
This module is part of the community.docker collection (version 3.13.3).
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_network_info.
Synopsis
Retrieves facts about a docker network.
Essentially returns the output of
docker network inspect <name>, similar to what community.docker.docker_network returns for a non-absent network.
Requirements
The below requirements are needed on the host that executes this module.
Docker API >= 1.25
backports.ssl_match_hostname (when using TLS on Python 2)
paramiko (when using SSH with
use_ssh_client=false)pyOpenSSL (when using TLS)
pywin32 (when using named pipes on Windows 32)
requests
Parameters
Parameter |
Comments |
|---|---|
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 Default: |
|
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 This option was called |
|
Path to the client’s TLS certificate file. If the value is not specified in the task and the environment variable |
|
Path to the client’s TLS key file. If the value is not specified in the task and the environment variable |
|
Debug mode Choices:
|
|
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, If the value is not specified in the task, the value of environment variable Default: |
|
The name of the network to inspect. When identifying an existing network name may be a name or a long or short network ID. |
|
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 |
|
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 Default: |
|
Secure the connection to the API by using TLS without verifying the authenticity of the Docker host server. Note that if If the value is not specified in the task, the value of environment variable Choices:
|
|
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 Note that this option had a default value |
|
For SSH transports, use the Choices:
|
|
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 Choices:

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.This module does not use the Docker SDK for Python to communicate with the Docker daemon. It uses code derived from the Docker SDK or Python that is included in this collection.
Examples
- name: Get infos on network
community.docker.docker_network_info:
name: mydata
register: result
- name: Does network exist?
ansible.builtin.debug:
msg: "The network {{ 'exists' if result.exists else 'does not exist' }}"
- name: Print information about network
ansible.builtin.debug:
var: result.network
when: result.exists
