Puppet installs too many dependencies

Question

I have a puppet class 'php' which looks like the following:

    class php {
  case $operatingsystem {
    debian: {
      package {'php5-common':
        ensure => latest,
        provider => apt,
       }
      package {'php5-mysql': ensure => latest, provider => apt}
      package {'php5-gd': ensure => latest, provider => apt}
      package {'php5-fpm': ensure => latest, provider => apt}
      package {'php5-mcrypt': ensure => latest, provider => apt}
      package {'php5-memcache': ensure => latest, provider => apt}
    }
  }

  service { 'php5-fpm':
    ensure => running,
    enable => true,
  }
} 

I include the php class in the node configuration in /etc/puppet/manifests/site.pp

It looks like

node 'example' {
  include php
}

When I run puppet agent -t on the client it installs the packages, but it installs kind of too much. It also installs apache and I don't know where it gets it from. I don't have any config in puppet for apache.

I guess it's using the debian recommendations or suggestions, but I'm not sure, because I disabled that on the server.

cat > /etc/apt/apt.conf.d/01norecommend 

The log output on the client is

When I run apt-get install $php-package-names it won't install apache, just when I use apache. That's kind of annoying, because I'm going to use nginx.

Do you have an idea how I can get puppet to install the packages normally without apache as dependency?

Answer 1

Make php5-fpm install before the others with require.

The gd, memcache, mcrypt, and mysql packages require the virtual package phpapi-20100525, which is provided by libapache2-mod-php5 or by php5-fpm.

When you install them in a single command, it's already installing one of the packages that fulfills the requirement. When run separately as Puppet resources, apt is forced to pick one and picks the Apache library.
