## [Example Playbook](#example-playbook)
|
|
|
|
This example is taken from `molecule/default/converge.yml` and is tested on each push, pull request and release.
|
|
```yaml
|
|
---
|
|
- name: Converge
|
|
hosts: all
|
|
become: yes
|
|
gather_facts: yes
|
|
|
|
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`:
|
|
```yaml
|
|
---
|
|
- name: Prepare
|
|
hosts: all
|
|
gather_facts: no
|
|
become: yes
|
|
|
|
roles:
|
|
- role: robertdebock.bootstrap
|
|
- role: robertdebock.apt_autostart
|
|
- role: robertdebock.core_dependencies
|
|
```
|
|
