Instructions

• Install Docker.
• pip install -r requirements.txt to install Ansible
• Generate ssh keys for local test: ssh-keygen -t rsa -f dev/id_rsa
• Run it: dev/test.sh -fc
• dev/test.sh --help for available options.

Files in dev/:

• dev/inventory - hosts setup for local dev. Mirrors main ansible inventory file, but with *.ans.local hostnames.
• dev/vars.yml - put vars in there that should override vars from main ansible config.
• dev/Dockerfile - Dockerfile for test containers.

How it works:

• Docker image ansible_local_test is built.
• dev/inventory is parsed to pull out hostnames like *.ans.local.
• For each hostname:
  • An alias IP is created and added to lo0.
  • An /etc/hosts entry is added pointing to corresponding alias ip.
  • Docker container started from ansible_local_test for each hostname:
  • Container name is hostname.
  • Port 22 exposed on alias IP.
  • Host docker socket mounted into container.
