Ansible is a configuration management tool that allows automation of IT tasks, including managing Docker containers. To manage Docker containers through Ansible, it leverages the Docker Python library, which provides an API for interacting with Docker.
Ansible provides several modules for managing Docker containers, such as
docker_login. These modules utilize the Docker Python library to connect to the Docker daemon running on the target host.
To connect to the Docker daemon, Ansible uses the Docker API endpoint, which is typically
unix:///var/run/docker.sock. Ansible also supports connecting to the Docker API over a TCP socket, which can be specified using the
Once the connection is established, Ansible can perform various tasks, such as creating and managing Docker containers, pulling and pushing Docker images, and managing Docker networks and volumes.
In summary, Ansible modules connect to the Docker API using the Docker Python library and the API endpoint, enabling automation of Docker container management tasks.
Ansible playbookhow to use the docker_container module to manage Docker containers
An example Ansible playbook that demonstrates how to use the
docker_container module to manage Docker containers:
- name: Manage Docker containers with Ansible
become: true tasks:
In this playbook, we have three tasks that demonstrate how to use the
- Start a container: This task uses the
docker_containermodule to start a container with the name
my_containerand the image
my_image. We also map port 80 on the host to port 80 in the container.
- Stop a container: This task uses the
docker_containermodule to stop the container named
- Remove a container: This task uses the
docker_containermodule to remove the container named
You can run this playbook using the
Make sure to replace
my_docker_host with the name or IP address of your Docker host, and
my_image with the name of the Docker image you want to use.
