CentOS 8.x Ansible Test Image

CentOS 8.x Docker container for Ansible playbook and role testing.

How to Build

This image is built on Docker Hub automatically any time the upstream OS container is rebuilt, and any time a commit is made or merged to the master branch. But if you need to build the image on your own locally, do the following:

1. Install Docker.
2. cd into this directory.
3. Run docker build -t centos8-ansible .

How to Use

1. Install Docker.
2. Pull this image from Docker Hub: docker pull v0rts/docker-centos8-ansible:latest (or use the tag you built earlier, e.g. centos8-ansible).
3. Run a container from the image: docker run --detach --privileged --volume=/sys/fs/cgroup:/sys/fs/cgroup:ro v0rts/docker-centos8-ansible:latest /usr/lib/systemd/systemd (to test my Ansible roles, I add in a volume mounted from the current working directory with --volume=`pwd`:/etc/ansible/roles/role_under_test:ro).
4. Use Ansible inside the container: a. docker exec --tty [container_id] env TERM=xterm ansible --version b. docker exec --tty [container_id] env TERM=xterm ansible-playbook /path/to/ansible/playbook.yml --syntax-check
