Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

-
  hosts: Hatena-Antenna2_backend
  vars:
    - mackerel_agent_apikey: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
    - mackerel_agent_roles:
      - "My-Service:app"
      - "Another-Service:db"
  roles:
    - mackerelio.mackerel-agent

How to test

Test cases are defined in test.yml. To add a new test:

  • Add a test case in tests/test.yml. The case name is defined in tags.
  • Run ./tests/run -w test_case_name. This command will generate tests/cases/test_case_name directory.
  • Check ./tests/run command to exit with 0.
  • Run git add tests/ and commit.
