This section outlines the introduction of containerization in Red Hat OpenStack Platform.
- Containerized Overcloud
The Red Hat OpenStack Platform director now creates an overcloud consisting of containerized services. Users can implement the following sources for their container images:
Locally from the undercloud (images initially pulled from
Red Hat Satellite 6 (images synchronized from
The overcloud continues to support composable service infrastructure using containers to augment existing services. Note that the only services not containerized by default are:
OpenStack Networking (neutron)
OpenStack Block Storage (cinder)
OpenStack Shared File Systems (Manila)
Red Hat provides the containers for these services as a technical preview only.
- Containerized Upgrades
The Red Hat OpenStack Platform director provides an upgrade path from a non-containerized Red Hat OpenStack Platform 11 overcloud to containerized Red Hat OpenStack Platform 12 overcloud.
