Lesson 1: Initialize a role and pass a test

• home
• next

To get the workshop going, we start with a rather simple task by just initializing a molecule test and pass the tests.

You can play around with it, by editing for example some boolean values and see how the linter kicks in.

Initialize

docker run \
  -v $(pwd):$(pwd) -w $(pwd) \
  --user root \
  quay.io/ansible/molecule:3.0.2 \
  /bin/sh -c "molecule init role --verifier-name testinfra rolename"

Now navigate into the folder of your new role.

cd rolename

copy the .yamllint

add a .yamllin file to folder molecule/default/.yamllint

---
# Based on ansible-lint config
extends: default

rules:
  braces:
    max-spaces-inside: 1
    level: error
  brackets:
    max-spaces-inside: 1
    level: error
  colons:
    max-spaces-after: -1
    level: error
  commas:
    max-spaces-after: -1
    level: error
  comments: disable
  comments-indentation: disable
  document-start: disable
  empty-lines:
    max: 3
    level: error
  hyphens:
    level: error
  indentation: disable
  key-duplicates: enable
  line-length: disable
  new-line-at-end-of-file: disable
  new-lines:
    type: unix
  trailing-spaces: disable
  truthy: enable

Edit

To get the linting going just add this to your molecule/default/molecule.yml

lint: |
  set -e
  yamllint .
  ansible-lint .

Now you have to edit the meta/main.yml to pass the linter.

Run the test

docker run \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v $(pwd):$(pwd) -w $(pwd) \
  --user root \
  quay.io/ansible/molecule:3.0.2 \
  /bin/sh -c "pip3 install testinfra; molecule test"
