Ansible docker_container Create Network

Automating container deployment and network connections is a key aspect of good DevOps practices.

Today, we are going to take a look at how to use Ansible to seamlessly create a Docker container and connect it to a specific network using the docker_container module. This offers us a streamlined and reproducible deployment of our Dockerized applications.

Ansible Playbook Example

Here is an example of an Ansible playbook that creates a Docker container and connects it to a network:

Let’s take a closer look at this example:

• Create Docker Network:

  The first task, `docker_network`, is responsible for creating a Docker network named `my_network`. We can customize network options according to our specific requirements.
• Create Docker Container:

  The second task, `docker_container`, creates a Docker container named `my_container` using the specified image `my_image`. The `networks` parameter connects the container to the `my_network` network.

Before running the playbook, make sure the `docker-py` Python library is installed, as Ansible relies on it to communicate with the Docker API. We can install it using the following command:

pip install docker

Running the Ansible Playbook

Once we install the required library, we can execute our Ansible playbook:

ansible-playbook your_playbook.yml

Now, when we run the playbook, it will create a Docker network and a Docker container connected to that network. Remember to customize the playbook according to our specific use case, modifying parameters like container properties, network options, etc.
