Puppet module for managing CVMFS.

Table of Contents

1. Overview - What is the cvmfs module?

Overview

This module is intended to be used to manage CVMFS customizations. CVMFS is an HTTP based filesystem, part of the CernVM project. Both the client and server setups are supported. The server setup need a recent kernel (>= 4.2.0) to work properly via OverlayFS. The kernel-ml series from elrepo is available for both el6 and el7.

Usage

Client example

This is a simple example to add the atlas and sft CERN repositories, using a quota limit of 10 GB for the cache size and a local squid proxy mysquid.example.com. The module will use the current defaults:

• repositories = 'sft.cern.ch'
• quota_limit = 30000
• no http_proxy
• default cache base

Defining a cvmfs client customization

class { 'cvmfs::client':
    repositories => 'atlas.cern.ch,sft.cern.ch',
    quota_limit  => 10000,
    http_proxy   => 'http://mysquid.example.com:3128',
    cache_base   => '/var/cache/cvmfs'
}

Server example

This is a simple example to configure a server. It requires a recent kernel (> 4.2.0) to work properly.

include '::cvmfs::server'

Adding a repository

You can add custom repositories using in the following way:

cvmfs::repository {'myrepo.example.com':
   cvmfs_server_url => 'http://cvmfs.example.com/cvmfs/myrepo.example.com',
   cvmfs_public_key => 'puppet:///modules/myrepo/myrepo.example.com.pub',
   cvmfs_key_dir    => '/myrepo',
}

Where:

• cvmfs_server_url: repository URL
• cvmfs_public_key: public key of the repository
• cvmfs_key_dir: (optional) subdir in the keys directory to use

Limitations

• This module does not install the needed kernel for servers, this is left to the users. Only stratum-0 servers have been tested.
