Example Playbook

|
|
|
|
This example is taken from `molecule/resources/playbook.yml` and is tested on each push, pull request and release.

The machine you are running this on, may need to be prepared, I use this playbook to ensure everything is in place to let the role work.
|
|
```yaml
|
|
---
|
|
- name: Prepare
|
|
hosts: all
|
|
gather_facts: no
|
|
become: yes
|
|
serial: 30%
|
|
|
|
roles:
|
|
- role: robertdebock.bootstrap
|
|
```
|
|
|
|
After running this role, this playbook runs to verify that everything works, this may be a good example how you can use this role.
|
|
```yaml
|
|
---
|
|
- name: Verify
|
|
hosts: all
|
|
become: yes
|
|
gather_facts: yes
|
|
|
|
vars:
|
|
service_list:
|
|
- name: simple-service
|
|
|
|
tasks:
|
|
- name: start simple-service
|
|
service:
|
|
name: simple-service
|
|
state: started
|
|
|
|
- name: stop simple-service
|
|
service:
|
|
name: simple-service
|
|
state: stopped
|
|
|
|
- name: restart simple-service
|
|
service:
|
|
name: simple-service
|
|
state: restarted
|
|
|
|
```
|

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

Testing
|
|
-------
|
|
|
|
[Unit tests](https://travis-ci.org/robertdebock/ansible-role-service) are done on every commit, pull request, release and periodically.
|
|
|
|
If you find issues, please register them in [GitHub](https://github.com/robertdebock/ansible-role-service/issues)
|
|
|
|
Testing is done using [Tox](https://tox.readthedocs.io/en/latest/) and [Molecule](https://github.com/ansible/molecule):
|
|
|
|
[Tox](https://tox.readthedocs.io/en/latest/) tests multiple ansible versions.
|
|
[Molecule](https://github.com/ansible/molecule) tests multiple distributions.
|
|
|
|
To test using the defaults (any installed ansible version, namespace: `robertdebock`, image: `fedora`, tag: `latest`):
|
|
|
|
```
|
|
molecule test
|
|
|
|
# Or select a specific image:
|
|
image=ubuntu molecule test
|
|
# Or select a specific image and a specific tag:
|
|
image="debian" tag="stable" tox
|
|
```
|
|
|
|
Or you can test multiple versions of Ansible, and select images:
|
|
Tox allows multiple versions of Ansible to be tested. To run the default (namespace: `robertdebock`, image: `fedora`, tag: `latest`) tests:
|
|
|
|
```
|
|
tox
|
|
|
|
# To run CentOS (namespace: `robertdebock`, tag: `latest`)
|
|
image="centos" tox
|
|
# Or customize more:
|
|
image="debian" tag="stable" tox
|
|
```
