RHEA-2015:0147 - Product Enhancement Advisory

Topic

Updated OpenStack Orchestration packages that resolve various issues
are now available for Red Hat Enterprise Linux OpenStack Platform 6.0
(Icehouse) for RHEL 7.

Description

Red Hat Enterprise Linux OpenStack Platform provides the facilities
for building a private or public infrastructure-as-a-service (IaaS)
cloud running on commonly available physical hardware. This advisory
includes packages for:

• OpenStack Orchestration service

OpenStack Orchestration (heat) is a template-driven engine used to
specify and deploy configurations for Compute, Storage, and OpenStack
Networking. It can also be used to automate post-deployment actions,
which in turn allows automated provisioning of infrastructure, services,
and applications. Orchestration can also be integrated with Telemetry
alarms to implement auto-scaling for certain infrastructure resources.

With this release, the Orchestration service is now re-based to upstream
version 2014.2.1 (per BZ#1170346). This re-base applies several notable
fixes, including:

• Database migration between Red Hat Enterprise Linux OpenStack Platform 5

to the current version is now fixed.

• Floating IP resource dependencies are now present.
• The correct certificate keys are now passed to the Image service when

using SSL.

• Software deployments now update server lists (instead of incorrectly

replacing them).

• ResourceGroup updates now correctly update nested stacks.

The following resources and resource types are now supported:

• OS::Heat::SoftwareDeployments (resource), which can deploy a single

SoftwareConfiguration to a group of servers. This is very helpful for
deploying a cluster where each server has to be configured with the IP
addresses of every server in the cluster. (BZ#1131768)

• OS::Glance::Image (resource type), which allows images to be created

in the Image service as part of a Heat template. (BZ#1091579)

• OS::Nova::ServerGroup (resource), which allows you to apply scheduling

constraints (like affinity or anti-affinity) to a group of servers.
(BZ#1084266)

This update also applies the following fixes:

• The systemd script no longer explicitly sets a log file. This ensures

that syslog settings take precedence during logging. (BZ#1083057)

• The Orchestration service now allows the user to update a stack in a

FAILED state. Previously, failed stacks could only be deleted, not
updated. (BZ#1042160)

Solution

Before applying this update, ensure all previously released errata
relevant to your system have been applied.
