## [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

  vars:
    _service_test_command:
      default: /usr/bin/sleep
      Alpine: /bin/sleep
      Debian: /bin/sleep
      Ubuntu-16: /bin/sleep
      Ubuntu-18: /bin/sleep
    service_test_command: "{{ _service_test_command[ansible_distribution ~ '-' ~ ansible_distribution_major_version] | default(_service_test_command[ansible_os_family] | default(_service_test_command['default'])) }}"  # noqa 204 Just long.

  roles:
    - role: robertdebock.service
      service_list:
        - name: simple-service
          description: Simple Service
          start_command: "{{ service_test_command }} 3600"
          state: started
          enabled: yes
        - name: stopped-service
          description: Simple Service
          start_command: "{{ service_test_command }} 3601"
          state: stopped
          enabled: no
        - name: specific-stop-service
          description: Specific Stop Service
          start_command: "{{ service_test_command }} 1440"
          stop_command: /usr/bin/killall -f "sleep 1440"
        - name: specific-user-group-service
          description: Specific User Group Service
          start_command: "{{ service_test_command }} 28800"
          user_name: root
          group_name: root
        - name: specific-workingdirectory-service
          description: Specific WorkingDirectory Service
          start_command: "{{ service_test_command }} 57600"
          working_directory: /tmp
        - name: specific-pattern-service
          description: Specific Status Pattern Service
          start_command: "{{ service_test_command }} 115200"
          status_pattern: 115200
        - name: variable-service
          description: Service with environment variables
          start_command: "{{ service_test_command }} ${time}"
          environment_variables:
            time: 230400
        - name: pidfile-service
          description: Service with pidfile
          start_command: "{{ service_test_command }} 460800"
          pidfile: /var/run/pidfile-service.pid
        - name: environmentfile-service
          description: Service with environmentfile
          start_command: "{{ service_test_command }} 921600"
          environmentfile: /environmentfile.txt
```

The machine needs to be prepared in CI this is done using `molecule/resources/prepare.yml`:
```yaml
---
- name: Prepare
  hosts: all
  gather_facts: no
  become: yes
  serial: 30%

  roles:
    - role: robertdebock.bootstrap

  post_tasks:
    - name: place /environmentfile.txt
      copy:
        content: "value=variable"
        dest: /environmentfile.txt
        mode: "0644"
```

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)

These variables are set in `defaults/main.yml`:
```yaml
---
# defaults file for service

# service_list can contain a list of services to add to the system.
# The mandatory items for each item are:
# - name: The (short) name of the service, i.e. "tomcat".
# - description: A bit longer name, i.e. "Tomcat application server".
# - start_command: The command to start the daemon,
#   i.e. "/usr/local/bin/java -jar some.jar"
# The optional items are:
# - stop_command: By default the program that is started is found and stopped.
#   in case a running program is renamed or expanded (including a path) during
#   startup, you can specify a custom stop command here, i.e. "pkill foo"
# - status_pattern: What program (or pattern) to look for when finding the
#   status of a program, i.e. "artifactory".
# - type: How the program starts; "simple" or "forking". Simple means the
#   program runs on the foreground, i.e. "nc -l 1234". Forking means the
#   program itself forks, i.e. "nc -l 12345 &"
# - working_directory: The directory to cd into before starting the service.
# - environment_variables: A list for variables to set. for example:
#   environment_variables:
#     variable1: value1
#     variable2: value2
# - after: Start after the mentioned service.
# - restart_mode: The mode to use, for example "always".
# - restart_seconds: The time to allow restart to finish.
```
