Hello, In PuppetOpenstack we would like to use modulesync[1] in order to synchronize common file accross modules via a post-merged hook(WIP)[2]. In order for this script to work modulesync needs to be installed on the nodes. Modulesync isn't packaged for any distro AFAIK so it would need to be installed directly via rubygems. What would be the process to follow to require a gem to be installed on the base jenkins slave nodes? Thanks in advance, Related resources: * puppet-modulesync-configs: https://github.com/openstack/puppet-modulesync-configs * ML thread : http://lists.openstack.org/pipermail/openstack-dev/2015-May/064608.html [1] https://github.com/puppet-community/modulesync [2] https://review.openstack.org/#/c/189216/ -- Yanis Guenane
