## [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.postfix
|
|
postfix_relayhost: "[relay.example.com]"
|
|
postfix_myhostname: "smtp.example.com"
|
|
postfix_mydomain: "example.com"
|
|
postfix_myorigin: "example.com"
|
|
postfix_aliases:
|
|
- name: root
|
|
destination: test@example.com
|
|
```
|
|
|
|
The machine needs to be prepared in CI this is done using `molecule/resources/prepare.yml`:
|
|
```yaml
|
|
---
|
|
- name: Prepare
|
|
hosts: all
|
|
become: yes
|
|
gather_facts: no
|
|
|
|
roles:
|
|
- role: robertdebock.bootstrap
|
|
- role: robertdebock.core_dependencies
|
|
```
|
|
|
|

## [Role Variables](#role-variables)
|
|
|
|
These variables are set in `defaults/main.yml`:
|
|
```yaml
|
|
---
|
|
# defaults file for postfix
|
|
|
|
# These settings are required in postfix.
|
|
postfix_myhostname: "{{ ansible_fqdn }}"
|
|
postfix_mydomain: "{{ ansible_domain | default('localdomain', true) }}"
|
|
postfix_myorigin: "{{ ansible_domain | default('localdomain', true) }}"
|
|
|
|
# To "listen" on public interfaces, set inet_interfaces to something like
|
|
# "all" or the name of the interface, such as "eth0".
|
|
postfix_inet_interfaces: "loopback-only"
|
|
|
|
# Enable IPv4, and IPv6 if supported - if IPV4 only set to ipv4
|
|

# "192.168.0.0/24".
|
|
postfix_mynetworks: "127.0.0.0/8"
|
|
|
|
# These settings change the role of the postfix server to a relay host.
|
|
# postfix_relay_domains: "$mydestination"
|
|
|
|
# If you want to forward emails to another central relay server, set relayhost.
|
|
# use brackets to sent to the A-record of the relayhost.
