## [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
|
|
|
|
roles:
|
|
- role: robertdebock.postfix
|
|
postfix_relayhost: "[relay.example.com]"
|
|
postfix_myhostname: "smtp.example.com"
|
|
postfix_mydomain: "example.com"
|
|
postfix_myorigin: "example.com"
|
|
postfix_mynetworks:
|
|
- 127.0.0.0/8
|
|
- 192.168.0.0/16
|
|
postfix_aliases:
|
|
- name: root
|
|
destination: test@example.com
|
|
```
|
|
|
|
The machine needs to be prepared. In CI this is done using `molecule/default/prepare.yml`:
|
|
```yaml
|
|
---
|
|
- name: Prepare
|
|
hosts: all
|
|
become: yes
|
|
gather_facts: no
|
|
|
|
roles:
|
|
- role: robertdebock.bootstrap
|
|
- role: robertdebock.core_dependencies
|
|
```
|
|
|
|
Also see a [full explanation and example](https://robertdebock.nl/how-to-use-these-roles.html) on how to use these roles.

|
|
## [Role Variables](#role-variables)
