Note

Python3 is required for Ussuri and newer releases of OpenStack which is supported on RHEL 8 and CentOS 8. Train is also recommended to be installed on RHEL 8 or CentOS 8.

1. Download and install the python-tripleo-repos RPM from the appropriate RDO repository

   CentOS 8 and CentOS Strem 8

   Current Centos 8 RDO repository.

   sudo dnf install -y https://trunk.rdoproject.org/centos8/component/tripleo/current/python3-tripleo-repos-<version>.el8.noarch.rpm
   

   Note

   tripleo-repos removes any repositories that it manages before each run. This means all repositories must be specified in a single tripleo-repos call. As an example, the correct way to install the current and ceph repos is to run tripleo-repos current ceph, not two separate calls.

   Stable Branch

   Enable the appropriate repos for the desired release, as indicated below. Do not enable any other repos not explicitly marked for that release.

   Wallaby

   Enable the current Wallaby repositories

   sudo -E tripleo-repos -b wallaby current
   

   Ceph

   Include the Ceph repo in the tripleo-repos call

   sudo -E tripleo-repos -b wallaby current ceph
   

   Victoria

   Enable the current Victoria repositories

   sudo -E tripleo-repos -b victoria current
   

   Ceph

   Include the Ceph repo in the tripleo-repos call

   sudo -E tripleo-repos -b victoria current ceph
   

   Ussuri

   Enable the current Ussuri repositories

   sudo -E tripleo-repos -b ussuri current
   

   Ceph

   Include the Ceph repo in the tripleo-repos call

   sudo -E tripleo-repos -b ussuri current ceph
   

   Train

   Enable the current Train repositories

   sudo -E tripleo-repos -b train current
   

   Ceph

   Include the Ceph repo in the tripleo-repos call

   sudo -E tripleo-repos -b train current ceph
   

Warning

The remaining repositories configuration steps below should not be done for stable releases!

2. Run tripleo-repos to install the appropriate repositories. The option below will enable the latest master TripleO packages, the latest promoted packages for all other OpenStack services and dependencies and the latest stable Ceph packages. There are other repository configurations available in tripleo-repos, see its --help output for details.

   sudo -E tripleo-repos current-tripleo-dev ceph
