Example Playbook

Simple docker install:

- hosts: all
  roles:
  - role: 'docker-bare-metal'

Install docker and configure some insecure registries and mirrors:

- hosts: all
  roles:
  - role: 'docker-bare-metal'
  vars:
    docker_data_root: /repertoire/docker
    docker_insecure_registries:
      - adresse_1
      - adresse_2
    docker_registry_mirrors:
      - https://adresse_3

Tests

The tests use molecule + libvirt + kvm distant + testinfra, allowing on the fly multi-nodes clusters creation and system configuration checks

Tests execution with docker:

# interactive :
docker run --env-file molecule/common/env_local_tests.sh -v $(pwd):/sources/docker -w /sources/docker   -v ~/.vagrant.d/boxes/:/root/.vagrant.d/boxes/   -v /var/run/libvirt/libvirt-sock:/var/run/libvirt/libvirt-sock -it --entrypoint bash ulrichg/molecule-vagrant-libvirt:latest

# lint:
docker run --env-file molecule/common/env_local_tests.sh -v $(pwd):/sources/docker -w /sources/docker   -v ~/.vagrant.d/boxes/:/root/.vagrant.d/boxes/   -v /var/run/libvirt/libvirt-sock:/var/run/libvirt/libvirt-sock ulrichg/molecule-vagrant-libvirt:latest lint

# default scenario:
docker run --env-file molecule/common/env_local_tests.sh -v $(pwd):/sources/docker -w /sources/docker   -v ~/.vagrant.d/boxes/:/root/.vagrant.d/boxes/   -v /var/run/libvirt/libvirt-sock:/var/run/libvirt/libvirt-sock ulrichg/molecule-vagrant-libvirt:latest

# other scenario:
docker run --env-file molecule/common/env_local_tests.sh -v $(pwd):/sources/docker -w /sources/docker   -v ~/.vagrant.d/boxes/:/root/.vagrant.d/boxes/   -v /var/run/libvirt/libvirt-sock:/var/run/libvirt/libvirt-sock ulrichg/molecule-vagrant-libvirt:latest test -s cluster1master
