Github Action for Molecule

First GitHub action allows you to run Molecule using ansible collection structure.

In addition, this GH action supports GIT status after Molecule execution to help to track unexpected file changes. This check can be enforced and generate a failure if a change is detected.

Usage

To use the action simply create an main.yml (or choose custom *.yml name) in the .github/workflows/ directory. Basic example:

on: push

jobs:
  molecule:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v2

      - name: Run molecule action
        uses: arista-netdevops-community/[email protected]
        with:
          molecule_parentdir: 'ansible_collections/arista/cvp'
          molecule_command: 'test'
          molecule_args: '--all'
          ansible: ansible>=2.10
          pip_file: 'requirements.txt'
          check_git: true
          check_git_enforced: false

Local testing

To test action execution locally, configure variables in a file:

# cat test.env
INPUT_PIP_FILE=requirements.txt
INPUT_MOLECULE_PARENTDIR=/root/ansible_collections/arista/cvp
INPUT_MOLECULE_COMMAND=test
INPUT_MOLECULE_ARGS=--all

Then run docker container:

docker run --rm -it \
    -v ${PWD}:/root/ \                              # Local content shared with container
    -v /var/run/docker.sock:/var/run/docker.sock \  # Docker process required by molecule
    --env-file dev.env \                            # File with your variables
