- This puppet module installs and configures the openstack-bits of our infrastructure profiles in our installation
- git@github.com:ntnusky/role.git
- This puppet module defines which profiles a certain role contains. For instance it defines that our compute nodes needs nova and neutron compute, in addition to some baseconfigIt basicly ties several profiles to a host.

- This repository defines which puppet modules (and versions of these) should be downloaded in which puppet environments.

No modifications should be done directly to production (the ntnuit stackit and skyhigh environment). All changes should be done to a testing environment, and when they are tested they might be merged into master. If a suitable testing environment does not exist it can simply be created by creating a new branch in the r10k repository.
...
To deploy the new environment on the puppetmaster puppetmasters you would use r10k:
| Code Block | ||
|---|---|---|
| ||
root@manager.skylow:~# r10k deploy environment newEnvironment -pv
INFO -> Deploying environment /etc/puppet/environments/newEnvironment
...
INFO -> Deploying module /etc/puppet/environments/newEnvironment/modules/role

Have a node follow the new environment (without an ENC):
Which environment a certain host uses in puppet is defined in /etc/puppet/puppet.conf in each host. This file is managed by puppet, so to change the environment you need to update the node-specific hiera file (/etc/puppet/hieradata/nodes/fqdn.yaml) to include the following key:
- profile::puppet::environment: 'newEnvironment'
After a puppet run the node is configured to follow the new environment, so the next puppet-run at that point will be run using the new environment.
should use shiftleader.
Having a node follow the new environment (with an ENC):
If an ENC is used for puppet (iex. ForemanShiftLeader) the environment is set by the ENC. In this case the value in /etc/puppet/puppet.conf is overridden by the ENC at each puppet run, and the procedure to change environment without an ENC will not work. The value in /etc/puppet/puppet.conf needs to be a valid puppet environment however.
To change the active environment in Foreman Shiftleader you would select the host in the GUI and change it in the drop-down box for "environment".
...
- Merge the master branch of r10k to the production branch
- Deploy with r10kShiftleader.
- Wait for puppet, or run it manually
- Enjoy your newly updated openstack installation.
