I have been attempting to create a manifest for installing postgres 9.1 using puppet on a Centos 5 server. I have been trying to adapt the instructions at http://wiki.postgresql.org/wiki/YUM_Installation in order to achieve this and when I go through a manual process, I have been able to.

It would seem to me therefore that a puppet manifest containing

package { 'postgresql91-server':
  ensure => installed,
  source => 'http://yum.postgresql.org/9.1/redhat/rhel-5-x86_64/pgdg-centos91-9.1-4.noarch.rpm'
}

however on attempting to apply this manifest I get

err: /Stage[main]//Package[postgresql91-server]/ensure: change from absent to present failed: Could not find package postgresql91-server

Any expert puppeteers out there able to help me?

    Removed postgresql tag - this question applies to any package with dependencies not available in a local repository. +1 for including exact error message text, commands and (some) version numbers. Commented Dec 19, 2012 at 1:52

Add the repo to yum (using puppet of course), then specify the repo resource as a dependency of the package. This will make upgrading easier later on. See the puppet docs on yum repos for more info.

Thanks to all help from Steve and Paul. The final code that I have used is

yumrepo { "postgres":
  baseurl => "http://yum.postgesql.org/9.1/redhat/rhel-5x86_64/",
  descr => "Postgres 9.1 repository",
  enabled => 1,
  gpgcheck => 1
}

package { 'postgresql91-server' :
  ensure => installed,
}

This does the trick!

  • gpgcheck => 0 isn't the best idea if you can avoid that. Are postgresql really releasing unsigned RPMs in their yumrepo?

    I'll make a change to gpgcheck => 1 as they do sign their rpms. Thanks for the advice

According to https://puppet.com/docs/puppet/latest/types/package.html, source is dependent upon the underlying package provider supporting it. To my knowledge, yum doesn't allow arbitrary URLs - you must specify a repo (as Steve Wills mentioned).

You might be able to work around this by specifying 'provider => "rpm"' for just this package resource, but i've not tried this myself.

    Yum does allow arbitrary URLs, but it cannot work out that the URL is part of a yum respository and fetch dependencies from the same repository. You can install from a URL to an RPM only if you have a locally defined repo that contains all the dependencies or the dependencies of the package are already installed.

  • That is if the RPM is actually in a repo. YUM does not require it to be in a repo, it can even install from a local directory. The problem is Puppet 'assumes' it is part of a repo, even when it isn't!
