##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
Bazaar
CVS
Mercurial
Perforce
Subversion

Note: git is the only vcs provider officially supported by Puppet Labs.

##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.

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

##Usage

Note: git is the only vcsrepo provider officially supported by Puppet Labs.

###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 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:

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 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 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 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 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 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 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.
