## [Example Playbook](#example-playbook)
This example is taken from [`molecule/default/converge.yml`](https://github.com/robertdebock/ansible-role-fail2ban/blob/master/molecule/default/converge.yml) and is tested on each push, pull request and release.
```yaml
---
- name: Converge
hosts: all
become: true
gather_facts: true
roles:
- role: robertdebock.fail2ban
```
The machine needs to be prepared. In CI this is done using [`molecule/default/prepare.yml`](https://github.com/robertdebock/ansible-role-fail2ban/blob/master/molecule/default/prepare.yml):
```yaml
---
- name: Prepare
hosts: all
become: true
gather_facts: false
roles:
- role: robertdebock.bootstrap
- role: robertdebock.epel
```
