I used this to install a gem :-
package { 'rubyzip':
ensure => present,
provider => 'gem',
}
It installed fine, in this location :
/usr/local/share/gems/gems/rubyzip-1.1.7
gem env shows that the parent folder is on the gem path :-
- GEM PATHS:
- /home/vagrant/.gem/ruby
- /usr/share/gems
- /usr/local/share/gems
However, when a Puppet manifest attempts to make use of that gem, it
can't find it.
Puppet has its own location for gems, in this particular install its :
/opt/puppetlabs/puppet/lib/ruby/gems/2.1.0/gems
If I change the package to include that directory as an install option,
the gem is indeed installed there and Puppet can use it :-
package { 'rubyzip':
ensure => present,
provider => 'gem',
install_options => {
'--install-dir' => "/opt/puppetlabs/puppet/lib/ruby/gems/2.1.0"
}
}
However, this approach seems a bit of a hack and one that will
ultimately create a maintenance overhead as/when Puppet's version of
Ruby is updated, not to mention that we also run Puppet on other
platforms (including Windows) which have different paths. I could handle
that but it seems like there must be a better way of making this work
cross platform without resorting to hard-coded paths even if that is
parametrized.
Has anyone got a suggestion how to solve this one more elegantly?
You might create Gemfile/Gemfile.lock files that manage the versions you
expect Puppet to use.
# example code, I'm sure none of the paths and
# checks are actually correct.
# install bundler
exec { 'puppetserver install bundler':
command => 'puppetserver gem install bundler --no-ri --no-rdoc',
unless => 'puppetserver gem list | grep bundler',
}
# managed your Gemfile/Gemfile.lock as part of the repo
exec { 'puppet gems bundle install':
command => '/opt/puppetlabs/puppet/bin/bundle
/etc/puppetlabs/gems/Gemfile',
unless => 'bundle check',
}
