##Overview

The vcsrepo module lets you use Puppet to easily deploy content from your version control system (VCS).

##Module Description

The vcsrepo module provides a single type with providers to support the following version control systems:

* [Git](#git)
* [Bazaar](#bazaar)
* [CVS](#cvs)
* [Mercurial](#mercurial)
* [Perforce](#perforce)
* [Subversion](#subversion)

**Note:** `git` is the only vcs provider officially [supported by Puppet Labs](https://forge.puppetlabs.com/supported).

##Setup

###Setup Requirements

The `vcsrepo` module does not install any VCS software for you. You must install a VCS before you can use this module.

Like Puppet in general, the `vcsrepo` module does not automatically create parent directories for the files it manages. Make sure to set up any needed directory structures before you get started.

###Beginning with vcsrepo

To create and manage a blank repository, define the type `vcsrepo` with a path to your repository and supply the `provider` parameter based on the [VCS you're using](#usage).

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => git,
}
~~~

##Usage

**Note:** `git` is the only vcsrepo provider officially [supported by Puppet Labs](https://forge.puppetlabs.com/supported).

###Git

####Create a blank repository

To create a blank repository, suitable for use as a central repository, define `vcsrepo` without `source` or `revision`:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => git,
}
~~~

If you're managing a central or official repository, you might want to make it a bare repository. To do this, set `ensure` to 'bare':

~~~
vcsrepo { '/path/to/repo':
  ensure   => bare,
  provider => git,
}
~~~

####Clone/pull a repository

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => git,
  source   => 'git://example.com/repo.git',
}
~~~

If you want to clone your repository as bare or mirror, you can set `ensure` to 'bare' or 'mirror':

~~~
vcsrepo { '/path/to/repo':
  ensure   => mirror,
  provider => git,
  source   => 'git://example.com/repo.git',
}
~~~

By default, `vcsrepo` will use the HEAD of the source repository's master branch. To use another branch or a specific commit, set `revision` to either a branch name or a commit SHA or tag.

Branch name:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => git,
  source   => 'git://example.com/repo.git',
  revision => 'development',
}
~~~

SHA:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => git,
  source   => 'git://example.com/repo.git',
  revision => '0c466b8a5a45f6cd7de82c08df2fb4ce1e920a31',
}
~~~

Tag:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => git,
  source   => 'git://example.com/repo.git',
  revision => '1.1.2rc1',
}
~~~

To check out a branch as a specific user, supply the `user` parameter:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => git,
  source   => 'git://example.com/repo.git',
  revision => '0c466b8a5a45f6cd7de82c08df2fb4ce1e920a31',
  user     => 'someUser',
}
~~~

To keep the repository at the latest revision, set `ensure` to 'latest'.

**WARNING:** this overwrites any local changes to the repository:

~~~
vcsrepo { '/path/to/repo':
  ensure   => latest,
  provider => git,
  source   => 'git://example.com/repo.git',
  revision => 'master',
}
~~~

To clone the repository but skip initializing submodules, set `submodules` to 'false':

~~~
vcsrepo { '/path/to/repo':
  ensure     => latest,
  provider   => git,
  source     => 'git://example.com/repo.git',
  submodules => false,
}
~~~

####Use multiple remotes with a repository
In place of a single string, you can set `source` to a hash of one or more name => URL pairs:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => git,
  remote   => 'origin'
  source   => {
    'origin'       => 'https://github.com/puppetlabs/puppetlabs-vcsrepo.git', 
    'other_remote' => 'https://github.com/other_user/puppetlabs-vcsrepo.git'
  },
}
~~~

**Note:** if you set `source` to a hash, one of the names you specify must match the value of the `remote` parameter. That remote serves as the upstream of your managed repository.

####Connect via SSH

To connect to your source repository via SSH (e.g., 'username@server:…'), we recommend managing your SSH keys with Puppet and using the [`require`](http://docs.puppetlabs.com/references/stable/metaparameter.html#require) metaparameter to make sure they are present before the `vcsrepo` resource is applied.

To use SSH keys associated with a user, specify the username in the `user` parameter:

~~~
vcsrepo { '/path/to/repo':
  ensure     => latest,
  provider   => git,
  source     => 'git://username@example.com/repo.git',
  user       => 'toto', #uses toto's $HOME/.ssh setup
  require    => File['/home/toto/.ssh/id_rsa'],
}
~~~

###Bazaar

####Create a blank repository

To create a blank repository, suitable for use as a central repository, define `vcsrepo` without `source` or `revision`:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => bzr,
}
~~~

####Branch from an existing repository

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => bzr,
  source   => '/some/path',
}
~~~

To branch from a specific revision, set `revision` to a valid [Bazaar revision spec](http://wiki.bazaar.canonical.com/BzrRevisionSpec):

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => bzr,
  source   => '/some/path',
  revision => 'menesis@pov.lt-20100309191856-4wmfqzc803fj300x',
}
~~~

####Connect via SSH

To connect to your source repository via SSH (e.g., `'bzr+ssh://...'` or `'sftp://...,'`), we recommend using the [`require`](http://docs.puppetlabs.com/references/stable/metaparameter.html#require) metaparameter to make sure your SSH keys are present before the `vcsrepo` resource is applied:

~~~
vcsrepo { '/path/to/repo':
  ensure     => latest,
  provider   => bzr,
  source     => 'bzr+ssh://bzr.example.com/some/path',
  user       => 'toto', #uses toto's $HOME/.ssh setup
  require    => File['/home/toto/.ssh/id_rsa'],
}
~~~

###CVS

####Create a blank repository

To create a blank repository, suitable for use as a central repository, define `vcsrepo` without `source` or `revision`:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => cvs,
}
~~~

####Checkout/update from a repository

~~~
vcsrepo { '/path/to/workspace':
  ensure   => present,
  provider => cvs,
  source   => ':pserver:anonymous@example.com:/sources/myproj',
}
~~~

To get a specific module on the current mainline, supply the `module` parameter:

~~~
vcsrepo {'/vagrant/lockss-daemon-source':
  ensure   => present,
  provider => cvs,
  source   => ':pserver:anonymous@lockss.cvs.sourceforge.net:/cvsroot/lockss',
  module   => 'lockss-daemon',
}
~~~

To set the GZIP compression levels for your repository history, use the `compression` parameter:

~~~
vcsrepo { '/path/to/workspace':
  ensure      => present,
  provider    => cvs,
  compression => 3,
  source      => ':pserver:anonymous@example.com:/sources/myproj',
}
~~~

To get a specific revision, set `revision` to the revision number.

~~~
vcsrepo { '/path/to/workspace':
  ensure      => present,
  provider    => cvs,
  compression => 3,
  source      => ':pserver:anonymous@example.com:/sources/myproj',
  revision    => '1.2',
}
~~~

You can also set `revision` to a tag:

~~~
vcsrepo { '/path/to/workspace':
  ensure      => present,
  provider    => cvs,
  compression => 3,
  source      => ':pserver:anonymous@example.com:/sources/myproj',
  revision    => 'SOMETAG',
}
~~~

####Connect via SSH

To connect to your source repository via SSH, we recommend using the [`require`](http://docs.puppetlabs.com/references/stable/metaparameter.html#require) metaparameter to make sure your SSH keys are present before the `vcsrepo` resource is applied:

~~~
vcsrepo { '/path/to/repo':
  ensure     => latest,
  provider   => cvs,
  source     => ':pserver:anonymous@example.com:/sources/myproj',
  user       => 'toto', #uses toto's $HOME/.ssh setup
  require    => File['/home/toto/.ssh/id_rsa'],
}
~~~

###Mercurial

####Create a blank repository

To create a blank repository, suitable for use as a central repository, define `vcsrepo` without `source` or `revision`:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => hg,
}
~~~

####Clone/pull & update a repository

To get the default branch tip:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => hg,
  source   => 'http://hg.example.com/myrepo',
}
~~~

For a specific changeset, use `revision`:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => hg,
  source   => 'http://hg.example.com/myrepo',
  revision => '21ea4598c962',
}
~~~

You can also set `revision` to a tag:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => hg,
  source   => 'http://hg.example.com/myrepo',
  revision => '1.1.2',
}
~~~

To check out as a specific user:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => hg,
  source   => 'http://hg.example.com/myrepo',
  user     => 'user',
}
~~~

To specify an SSH identity key:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => hg,
  source   => 'ssh://hg@hg.example.com/myrepo',
  identity => '/home/user/.ssh/id_dsa1,
}
~~~

To specify a username and password for HTTP Basic authentication:

~~~
vcsrepo { '/path/to/repo':
  ensure   => latest,
  provider => hg,
  source   => 'http://hg.example.com/myrepo',
  basic_auth_username => 'hgusername',
  basic_auth_password => 'hgpassword',
}
~~~

####Connect via SSH 

To connect to your source repository via SSH (e.g., `'ssh://...'`), we recommend using the [`require` metaparameter](http://docs.puppetlabs.com/references/stable/metaparameter.html#require) to make sure your SSH keys are present before the `vcsrepo` resource is applied:

~~~
vcsrepo { '/path/to/repo':
  ensure     => latest,
  provider   => hg,
  source     => 'ssh://hg.example.com//path/to/myrepo',
  user       => 'toto', #uses toto's $HOME/.ssh setup
  require    => File['/home/toto/.ssh/id_rsa'],
}
~~~

###Perforce

####Create an empty workspace

To set up the connection to your Perforce service, set `p4config` to the location of a valid Perforce [config file](http://www.perforce.com/perforce/doc.current/manuals/p4guide/chapter.configuration.html#configuration.settings.configfiles) stored on the node: 

~~~
vcsrepo { '/path/to/repo':
  ensure     => present,
  provider   => p4,
  p4config   => '/root/.p4config'
}
~~~

**Note:** If you don't include the `P4CLIENT` setting in your config file, the provider generates a workspace name based on the digest of `path` and the node's hostname (e.g., `puppet-91bc00640c4e5a17787286acbe2c021c`):

####Create/update and sync a Perforce workspace

To sync a depot path to head, set `ensure` to 'latest':

~~~
vcsrepo { '/path/to/repo':
  ensure   => latest,
  provider => p4,
  source   => '//depot/branch/...'
}
~~~

To sync to a specific changelist, specify its revision number with the `revision` parameter:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => p4,
  source   => '//depot/branch/...',
  revision => '2341'
}
~~~

You can also set `revision` to a label:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => p4,
  source   => '//depot/branch/...',
  revision => 'my_label'
}
~~~

###Subversion

####Create a blank repository

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => svn,
}
~~~

####Check out from an existing repository

Provide a `source` pointing to the branch or tag you want to check out:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => svn,
  source   => 'svn://svnrepo/hello/branches/foo',
}
~~~

You can also designate a specific revision:

~~~
vcsrepo { '/path/to/repo':
  ensure   => present,
  provider => svn,
  source   => 'svn://svnrepo/hello/branches/foo',
  revision => '1234',
}
~~~

####Use a specific Subversion configuration directory 

Use the `configuration` parameter to designate the directory that contains your Subversion configuration files (typically, '/path/to/.subversion'):

~~~
vcsrepo { '/path/to/repo':
  ensure        => present,
  provider      => svn,
  source        => 'svn://svnrepo/hello/branches/foo',
  configuration => '/path/to/.subversion',
}
~~~

####Connect via SSH 

To connect to your source repository via SSH (e.g., `'svn+ssh://...'`), we recommend using the [`require` metaparameter](http://docs.puppetlabs.com/references/stable/metaparameter.html#require) to make sure your SSH keys are present before the `vcsrepo` resource is applied:

~~~
vcsrepo { '/path/to/repo':
  ensure     => latest,
  provider   => svn,
  source     => 'svn+ssh://svnrepo/hello/branches/foo',
  user       => 'toto', #uses toto's $HOME/.ssh setup
  require    => File['/home/toto/.ssh/id_rsa'],
}
~~~

##Limitations

Git is the only VCS provider officially [supported](https://forge.puppetlabs.com/supported) by Puppet Labs.

This module has been tested with Puppet 2.7 and higher.

The module has been tested on:

* CentOS 5/6/7
* Debian 6/7
* Oracle 5/6/7
* Red Hat Enterprise Linux 5/6/7
* Scientific Linux 5/6/7
* SLES 10/11/12
* Ubuntu 10.04/12.04/14.04

Testing on other platforms has been light and cannot be guaranteed.

##Development

Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can't access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.

We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.

You can read the complete module contribution guide [on the Puppet Labs wiki.](http://projects.puppetlabs.com/projects/module-site/wiki/Module_contributing)
