ansible-bundle

Small tool for automatic download roles and libs a-la-Gemfile

Preamble

As many roles have changed their configurations among time, anyone would use a specific version of a role (for instance, a commit, or a branch, or a tag). Moreover, a complex playbook could need different versions from the same role. This app will download roles (bundles, from now on) from their repositories before launching a playbook. That means that a role should be in its own repository.

Prerequisites

• Ansible. Any version.
• Git >= 1.8.5
• Python 2 >= 2.6

Installation

The easy way: pip

sudo pip install ansible-bundle

The not-that-easy way: from code

• Download latest release
• Run sudo python setup.py

Syntax

ansible-bundle FILEYAML [ansible-playbook-options] [ansible-bundle-options]

ansible-bundle, along the ansible-playbook parameters, has also these:

• --bundle-clean-roles Will clean roles and library directories before download (*)

• --bundle-dry Shows what will be run (as it won't download anything, also won't search for dependencies)

• --bundle-deps-only Don't run the playbook, just satisfy dependencies.

• --bundle-disable-color Useful for non-interactive consoles

• --bundle-workers concurrent connections when downloading/updating roles. Default: 1

• --bundle-safe-update Don't clean existing roles. (*)

(*) If both bundle-clean-roles and bundle-safe-update are set, bundle-clean-roles will take effect.

Configuration

ansible-bundle expects to find a [bundle] section into ansible.cfg, which may contain some of the command lines parameters:

• workers

• verbosity

• safe

And the following extra options:

• url: URL where the roles are located. For example, if role apache is in github.com/foo/roles/apache, the url should be set to github.com/foo/roles. Default is 'https://github.com'

bundle.cfg example

	[bundle]
	url='[e-mail]:devopsysadmin/ansible-roles'
	workers=5
	verbosity=1

Example of use

Given the following playbook (site.yml):

	- include: site-common.yml
	  tags:
	    - common

	- hosts: all
	  roles:
	    - postgresql@1.0
	    - { role: apache, version: '2.4' }

Running ansible-bundle site.yml will search roles into the site-common.yml file and add to download queue, which already includes postgresql 1.0 and apache master.

Please note that each role is intended to be in its own repository, not in a folder.

Changelog

v 0.6

• Syntax role/version changes to role@version. This simplifies the configuration in ansible.cfg and allows branches names such as feature/something in role version. If a versioned role with the previous syntax is found, will complain with a deprecation warning. The previous syntax will be obsoleted in v 0.7.
