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

This example is taken from [`molecule/default/converge.yml`](https://github.com/buluma/ansible-role-ssh_chroot_jail/blob/master/molecule/default/converge.yml) and is tested on each push, pull request and release.

```yaml
---
- name: Converge
hosts: all
become: true

vars:
ssh_chroot_l2chroot_path: /usr/bin/l2chroot
ssh_chroot_jail_users:
- name: foo
home: /home/foo
shell: /bin/bash

roles:
- role: buluma.ssh_chroot_jail
```

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

```yaml
---
- name: Prepare
hosts: all
become: yes
gather_facts: no

roles:
- role: buluma.bootstrap
```
