Puppet: Installing Oracle Java

Learn more about how CareerBuilder was able to resolve customer issues 5x faster by using Scalyr, the fastest log management tool on the market. 

In order to run the neo4j server on my Ubuntu 12.04 Vagrant VM I needed to install the Oracle/Sun JDK which proved to be more difficult than I’d expected.

I initially tried to install it via the OAB-Java script but was running into some dependency problems and eventually came across a post which specified a PPA that had an installer I could use.

I wrote a little puppet Java module to wrap the commands in:

class java($version) {
  package { "python-software-properties": }
 
  exec { "add-apt-repository-oracle":
    command => "/usr/bin/add-apt-repository -y ppa:webupd8team/java",
    notify => Exec["apt_update"]
  }
 
  package { 'oracle-java7-installer':
    ensure => "${version}",
    require => [Exec['add-apt-repository-oracle']],
  }
}

I then included this in my default node definition:

node default {
  class { 'java': version => '7u21-0~webupd8~0', }
}

Unfortunately when I ran that I ended up with the following error:

err: /Stage[main]/Java/Package[oracle-java7-installer]/ensure: change from purged to present failed: Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install oracle-java7-installer' returned 100: Reading package lists...

I came across this post on Ask Ubuntu which explained a neat trick for getting around it by making it look like we’ve agreed to the licence. This is done by passing options to debconf-set-selections.

For a real server I guess you’d want some step where a person accepts the licence but since this is just for my hacking it seems to make sense.

My new Java manifest looks like this:

class java($version) {
  package { "python-software-properties": }
 
  exec { "add-apt-repository-oracle":
    command => "/usr/bin/add-apt-repository -y ppa:webupd8team/java",
    notify => Exec["apt_update"]
  }
 
  exec {
    'set-licence-selected':
      command => '/bin/echo debconf shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections';
 
    'set-licence-seen':
      command => '/bin/echo debconf shared/accepted-oracle-license-v1-1 seen true | /usr/bin/debconf-set-selections';
  }
 
  package { 'oracle-java7-installer':
    ensure => "${version}",
    require => [Exec['add-apt-repository-oracle'], Exec['set-licence-selected'], Exec['set-licence-seen']],
  }
}
