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

This example is taken from [`molecule/default/converge.yml`](https://github.com/robertdebock/ansible-role-auditd/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.auditd
auditd_start_service: false
auditd_local_events: "no"
auditd_rules:
- file: /var/log/audit/
keyname: auditlog
- file: /etc/audit/
permissions:
- write
- attribute_change
keyname: auditconfig
- file: /etc/libaudit.conf
permissions:
- write
- attribute_change
keyname: auditconfig
- file: /etc/audisp/
permissions:
- write
- attribute_change
keyname: audispconfig
- file: /sbin/auditctl
permissions:
- execute
keyname: audittools
- file: /sbin/auditd
permissions:
- execute
keyname: audittools
- syscall: open
action: always
filter: exit
filters:
- auid!=4294967295
- auid!=unset
keyname: my_keyname
arch: b32
- syscall: adjtimex
action: always
filter: exit
keyname: time_change
- syscall: settimeofday
action: always
filter: exit
keyname: time_change
- action: always
filter: exit
filters:
- path=/bin/ping
- perm=x
- auid>=500
- auid!=4294967295
keyname: privileged
```

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

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

roles:
- role: robertdebock.bootstrap
```
