Red Hat Enterprise Linux

Red Hat OpenStack Platform 15 is supported on Red Hat Enterprise Linux 8. For information on installing Red Hat Enterprise Linux, see Product Documentation for Red Hat Enterprise Linux 8.

Red Hat OpenStack Platform

To install OpenStack components and their dependencies, use the Red Hat OpenStack Platform director. The director uses a basic OpenStack undercloud, which is used to provision and manage the OpenStack nodes in the final overcloud.

Be aware that you need one extra host machine for the installation of the undercloud, in addition to the environment necessary for the deployed overcloud. For more information, see the Director Installation and Usage guide.

High Availability

For the configuration of additional high availability components (for example, HAProxy), see the High Availability Deployment and Usage guide.

For information about configuring live migration, see Migrating virtual machine instances between Compute nodes in the Instances and Images Guide.

Octavia

The OpenStack Load-balancing service (Octavia) provides a Load Balancing-as-a-Service (LBaaS) version 2 implementation for Red Hat OpenStack Platform director installations. To use Load Balancing-as-a-Service, see Load Balancing-as-a-Service (LBaaS) with Octavia in the Networking Guide.

Pacemaker

Pacemaker is integrated into Red Hat Enterprise Linux as an add-on. To set up Red Hat Enterprise Linux for high availability, see the Configuring and managing high availability clusters guide.
