Puppet Mrepo

This module creates and synchronizes rpm based repositories by managing mrepo.

Synopsis

Install and configure a basic mrepo installation

node default {
  class { "mrepo": }
}

Override default values and enable redhat network support for use in other classes

class { "mrepo::params":
  selinux       => true,
  rhn           => true,
  rhn_username  => "user",
  rhn_password  => "pass",
}

Mirror multiple centos 5 repositories

mrepo::repo { "centos5-x86_64":
  ensure    => present,
  update    => "nightly",
  repotitle => "CentOS 5.6 64 bit",
  arch      => "x86_64",
  release   => "5.6",
  urls      => {
    addons      => 'rsync://mirrors.kernel.org/centos/$release/addons/$arch/',
    centosplus  => 'rsync://mirrors.kernel.org/centos/$release/centosplus/$arch/',
    updates     => 'rsync://mirrors.kernel.org/centos/$release/updates/$arch/',
  }
}

mrepo::repo { "centos5-i386":
  ensure    => present,
  update    => "nightly",
  repotitle => "CentOS 5.6 64 bit",
  arch      => "i386",
  release   => "5.6",
  urls      => {
    addons      => 'rsync://mirrors.kernel.org/centos/$release/addons/$arch/',
    centosplus  => 'rsync://mirrors.kernel.org/centos/$release/centosplus/$arch/',
    updates     => 'rsync://mirrors.kernel.org/centos/$release/updates/$arch/',
  }
}

Mirror multiple rhel channels

mrepo::repo { "rhel6server-x86_64":
  ensure     => present,
  update     => "nightly",
  repotitle  => 'Red Hat Enterprise Linux Server $release ($arch)',
  rhn        => true,
  arch       => "x86_64",
  release    => "6",
  rhnrelease => "6Server",
  iso        => 'rhel-server-6.0-$arch-dvd.iso',
  urls       => {
    updates       => 'rhns:///rhel-$arch-server-6',
    vt            => 'rhns:///rhel-$arch-server-vt-6',
    supplementary => 'rhns:///rhel-$arch-server-supplementary-6',
    fasttrack     => 'rhns:///rhel-$arch-server-fasttrack-6',
    hts           => 'rhns:///rhel-$arch-server-hts-6',
    rhn-tools     => 'rhns:///rhn-tools-rhel-$arch-server-6',
  }
}

Usage

If you need to customize the mrepo default settings, include the mrepo::params class and include the appropriate variables. Else, you should be able to use the mrepo::repo by itself to instantiate repositories.

For class/define specific documentation, view the puppet doc in the given file.

Prerequisites

This module expects the following modules to be available:

• puppetlabs-apache
• puppetlabs-stdlib
• puppetlabs-vcsrepo

It also is configured for a redhat derived system and makes assumptions about the available users and groups. Alternate parameters may override these assumptions.

Mirror data can grow extremely large, so you will want to ensure that src_root is located on a large volume.

If you are planning on using ISOs, you will also need fuse-iso.

Repository URL formatting

You can take advantage of the variables that mrepo itself supports when defining a repository or ISO to mirror. Mrepo uses the following variables:

• $dist is set to the title of the resource
• $arch is set to the arch parameter
• $nick is set to $dist-$arch
• $repo is set to the key of the specific repository
• $release is set to the release parameter

Note that these are variables within mrepo; if you are using them, make sure to surround the string in single quotes so puppet doesn't try to expand them.

So this:

mrepo::repo { "centos5-x86_64":
  ensure    => present,
  update    => "nightly",
  repotitle => "CentOS 5.6 64 bit",
  arch      => "x86_64",
  release   => "5.6",
  urls      => {
    addons      => 'rsync://mirrors.kernel.org/centos/$release/$repo/$arch/',
    centosplus  => 'rsync://mirrors.kernel.org/centos/$release/$repo/$arch/',
    updates     => 'rsync://mirrors.kernel.org/centos/$release/$repo/$arch/',
  }
}

Is equivalent to this:

mrepo::repo { "centos5-x86_64":
  ensure    => present,
  update    => "nightly",
  repotitle => "CentOS 5.6 64 bit",
  arch      => "x86_64",
  release   => "5.6",
    addons      => 'rsync://mirrors.kernel.org/centos/5.6/addons/x86_64/',
    centosplus  => 'rsync://mirrors.kernel.org/centos/5.6/centosplus/x86_64/',
    updates     => 'rsync://mirrors.kernel.org/centos/5.6/updates/x86_64/',
  }
}

Be warned that you can make a repository with the name of 'release'; however, this will overwrite the actual release variable. If you have a repository with a name of release, change the key to something else, and explicitly define the url instead of using a variable.

For full details on how mrepo is used, see the mrepo usage page.

Caveats

SELinux

Default SELinux policy prevents the httpd context from manipulating loopback devices without having an explicit httpd context. This can be corrected by changing the context as a mount option for a regular mount. However, fuseiso does not have the capability to change selinux contexts. If you are planning on mounting ISOs, either do so as root, change the httpd context to permit fuseiso to run using audit2allow, or disable SELinux. If neither of these are viable options, you can locate and mirror an outside repository of the ISO data.

Further clarification of this issue can be found on the repoforge tools list.

Fuse ISO

Fuse iso is not available in any yum repository. You will need to locate an RPM or source file and install it for yourself. In addition, if you are using a non-root user to mount the ISOs, you will need to ensure that the user is in the 'fuse' group.
