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

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 <| |>
