php-ansible library

This library is a OOP-wrapper for the ansible provisioning tool. I intend to use this library for a symfony2 bundle and also a deployment GUI, based on php/symfony2. The current implementation is feature-complete for the ansible-playbook and ansible-galaxy commands.

Prerequisites

Your OS should be a flavor of linux and ansible has to be installed. It's easiest if ansible is in PATH :-) The library tries to find ansible-playbook and ansible-galaxy by itself or use the paths/executables you provide.

Usage

First instantiate the base object which works as a factory for the commands. Only the first parameter is mandatory, and provides the library with the path to your ansible deployment file structure.

Optionally, you can specify the path of your ansible-playbook and ansible-galaxy commands, just in case they are not in the PATH.

You can also pass any PSR compliant logging class to have further details logged. This is especially useful to have the actual run command logged.

Playbooks

Then you can use the object just like in your previous ansible deployment. If you don't specify an inventory file with , the wrapper tries to determine one, based on your playbook name:

This will create following ansible command:

For the execute command you can use a callback to get real-time output of the command:

If no callback is given, the method will return the ansible-playbook output as a string, so you can either or directly pipe it into a log/whatever.

You can also pass an external YML/JSON file as extraVars containing a complex data structure to be passed to Ansible:

You can have a Json output adding json() option that enable 'ANSIBLE_STDOUT_CALLBACK=json' env vars to make a json output in ansible.

Galaxy

The syntax follows ansible's syntax with one deviation: list is a reserved keyword in php (array context) and therefore I had to rename it to "modulelist()".

would generate:

You can access all galaxy commands:

• init()
• info()
• install()
• help()
• modulelist()
• remove()

You can combine the calls with their possible arguments, though I don't have any logic preventing e.g. from being applied to e.g. info().

Possible arguments/options:

• initPath()
• offline()
• server()
• force()
• roleFile()
• rolesPath()
• ignoreErrors()
• noDeps()

Process timeout

Default process timeout is set to 300 seconds. If you need more time to execute your processes: Adjust the timeout :-)

Thank you for your contributions!

thank you for reviewing, bug reporting, suggestions and PRs :-) xabbuh, emielmolenaar, saverio, soupdiver, linaori, paveldanilin and many others!

Future features

The Next steps for implementation are:

• improve type handling and structure, due to overall complexity of the playbook at the moment
• scalar typehints all over the place
• provide docker support for development
• move to php8.0 exclusively for the next major release
• wrapping the library into a bundle -> maybe
• provide commandline-capabilities -> maybe
