Run `apt-get update` before installing other packages with Puppet

Question

I\'m trying to create puppet module which automates installation of zend server CE, this is not important here, but steps are as following

1. update /etc/apt/sour

Answer 1

Adding this snippet of voodoo worked for us:

  Apt::Pin <| |> -> Package <| |>
  Apt::Source <| |> -> Package <| |>

This forced an update. YMMV.

Answer 2

In Puppet 3 this can be done by realizing virtual resources using resource collectors

# so you don't have to fully qualify paths to binaries
Exec { path => ['/usr/bin'] }    

# virtual resource
@exec { 'sudo apt-get update':
   tag => foo_update
}

# realize resource. filter by arbitrary "foo_update"
# tag and relate it to all Package resources
Exec <| tag == foo_update |> -> Package <| |>

Answer 3

You need to specify the dependency relationships. The easiest/cleanest approach is to use the require parameter which is available for all resource types.

package { "zend-server-ce-php-5.2":
  ensure  => latest,
  require  => Exec['apt-get update'],
}

etc..

Answer 4

I tried previous variant but it doesn't work for me on Ubuntu 10.04

Finaly I prepared the following script, that runs update everytime the repository is older than one week:

exec { 'apt-get update':
    command => "/usr/bin/apt-get update",
    onlyif => "/bin/bash -c 'exit $(( $(( $(date +%s) - $(stat -c %Y /var/lib/apt/lists/$( ls /var/lib/apt/lists/ -tr1|tail -1 )) )) <= 604800 ))'"
}

Hope it helps.

I prefer to put apt-upgrade into a separate stage running before the main stage, so I don't have to hard-wire any dependencies. Check here: http://docs.puppetlabs.com/puppet/2.7/reference/lang_run_stages.html.

A simple example would look like below. It implies you have a separate class for doing the actual apt-update:

stage { "init": before  => Stage["main"] }

class {"apt-update": 
  stage => init, 
  apt_mirror => $apt_mirror 
}

Check my sample LAMPP-box on github to see how the pieces fit together: https://github.com/joerx/vagrant-lampp

Note: be careful with apt-upgrade, as some base boxes break by things like kernel upgrades.

You should really be using the apt module to create sources and add keys: https://forge.puppet.com/puppetlabs/apt

If you're using hiera:

apt::sources:
  'artifactory-pro-debs':
    location: 'http://repos.zend.com/zend-server/deb'
    release: 'server
    repos: 'non-free'
    key:
      source: 'http://repos.zend.com/zend.key'
