## [Example Playbook](#example-playbook)
|
|
|
|
This example is taken from `molecule/resources/converge.yml` and is tested on each push, pull request and release.
|
|
```yaml
|
|
---
|
|
- name: Converge
|
|
hosts: all
|
|
become: yes
|
|
gather_facts: yes
|
|
|
|
roles:
|
|
- role: robertdebock.molecule
|
|
```
|
|
|
|
The machine needs to be prepared in CI this is done using `molecule/resources/prepare.yml`:
|
|
```yaml
|
|
---
|
|
- name: Prepare
|
|
hosts: all
|
|
gather_facts: no
