Rocky Linux 8 Container Image for Ansible Testing

This Dockerfile builds a Rocky Linux 8 based container, capable of using systemd, mainly for Ansible role testing.

How to build locally

1. Install Docker.

2. Clone the repository:

   git clone https://github.com/chzerv/rockylinux8-systemd-ansible.git

3. cd into the directory and run docker build -t rockylinux8-systemd-ansible .

docker can be substituted for any other container engine, e.g., Podman.

How to use

1. Install Docker.

2. Pull this image from Docker hub:

   docker pull chzerv/rockylinux8-systemd-ansible:latest

If you built the image locally, you can use that instead.

Now, you can either run commands directly inside the container:

docker run -d --privileged --volume=/sys/fs/cgroup:/sys/fs/cgroup:ro rockylinux8-systemd-ansible:latest ansible --version

Or, you can use it with molecule:

# molecule/default/molecule.yml

  name: galaxy

  set -e
  yamllint .
  ansible-lint

Notes

This image is used for testing Ansible roles and playbooks locally and/or in CI, hence, security is not a concern. It is not intended or recommended to use this image in production environments.
