Overview¶

Base OS¶

The OpenStack Technical Committee (TC) has defined the current CI strategy to include the latest Ubuntu release and the latest RHEL release.

• Ubuntu: current LTS release plus current development release
• Fedora: current release plus previous release
• RHEL/Centos: current major release
• Other OS platforms may continue to be included but the maintenance of those platforms shall not be assumed simply due to their presence. Having a listed point-of-contact for each additional OS will greatly increase its chance of being well-maintained.
• Patches for Ubuntu and/or Fedora will not be held up due to side-effects on other OS platforms.

Databases¶

As packaged by the host OS

• MySQL

Queues¶

As packaged by the host OS

• Rabbit

Web Server¶

As packaged by the host OS

• Apache

OpenStack Network¶

• Neutron: A basic configuration approximating the original FlatDHCP mode using linuxbridge or OpenVSwitch.

Services¶

The default services configured by DevStack are Identity (keystone), Object Storage (swift), Image Service (glance), Block Storage (cinder), Compute (nova), Networking (neutron), Dashboard (horizon)

Additional services not included directly in DevStack can be tied in to stack.sh using the plugin mechanism to call scripts that perform the configuration and startup of the service.

Node Configurations¶

• single node
• multi-node configurations as are tested by the gate

Exercises¶

The DevStack exercise scripts are no longer used as integration and gate testing as that job has transitioned to Tempest. They are still maintained as a demonstrations of using OpenStack from the command line and for quick operational testing.
