Add cgroup memory limits to the jenkins_slave module. Nodes including jenkins_slave::cgroups will have the jenkins user's processes limited to use only 90% of the nodes available memory. There are two exceptions to this. The jenkins process run by the jenkins user will not have its memory capped. Also there is a soft memory limit of total physical memory * 0.75. If there is memory contention the jenkins user processes may get only 75% of available memory. Change-Id: If4a6439b536df4003d74fd1a93686c1c2401ae20
These are a set of puppet manifests and modules that are currently being used to manage some of the efforts of the OpenStack CI project. They are quite bare and crappy at the moment, but should grow soon.
Additionally, there is a script, make_puppet_lp.py which is used to generate a few lists of users from launchpad teams, to make management and population of user accounts on different types of servers easier.
There are currently two different entry points, the slave.pp and the server.pp manifest.
slave.pp is intended to be for jenkins slaves and adds all members of ~openstack-ci-admins
server.pp is intended as the base for other servers and adds members of ~openstack-admins
Puppet needs to be installed via gems, because we use the pip package provider for one of the packages and that is only in 2.7.
For instance:
/var/lib/gems/1.8/bin/puppet apply --modulepath=pwd/modules manifests/slave.pp
or
/var/lib/gems/1.8/bin/puppet apply --modulepath=pwd/modules manifests/server.pp
