## [Example Playbook](#example-playbook)

This example is taken from [`molecule/default/converge.yml`](https://github.com/robertdebock/ansible-role-dhcpd/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

vars:
dhcpd_subnets:
- network: "{{ ansible_default_ipv4.network }}"
netmask: "255.255.255.0"

roles:
- role: robertdebock.dhcpd
```

The machine needs to be prepared. In CI this is done using [`molecule/default/prepare.yml`](https://github.com/robertdebock/ansible-role-dhcpd/blob/master/molecule/default/prepare.yml):

```yaml
---
- name: Prepare
hosts: all
become: true
gather_facts: false

roles:
- role: robertdebock.bootstrap
- role: robertdebock.apt_autostart
- role: robertdebock.core_dependencies
```
