RDO Caracal 2024.1 Released

The RDO community is pleased to announce the general availability of the RDO build for OpenStack 2024.1 Caracal for RPM-based distributions, CentOS Stream and Red Hat Enterprise Linux. RDO is suitable for building private, public, and hybrid clouds. Caracal is the 29th release from the OpenStack project, which is the work of more than 1,000 contributors from around the world.

The release is already available for CentOS Stream 9 on the CentOS mirror network in:

     http://mirror.stream.centos.org/SIGs/9-stream/cloud/x86_64/openstack-caracal/ 

The RDO community project curates, packages, builds, tests and maintains a complete OpenStack component set for RHEL and CentOS Stream and is a member of the CentOS Cloud SIG. The Cloud SIG focuses on delivering a great user experience for CentOS users looking to build and maintain their own on-premise, public or hybrid clouds.

All work on RDO and on the downstream release, Red Hat OpenStack Platform, is 100% open source, with all code changes going upstream first.

The highlights of the broader upstream OpenStack project may be read via https://releases.openstack.org/caracal/highlights.html but here are some highlights:

• Drivers with inactive CI were marked unsupported including Windows iSCSI Driver, Windows SMB Driver, Dell SC Series Storage Driver (iSCSI, FC), Dell VNX Storage Driver (FC, iSCSI) and Dell XtremeIO Storage Driver (iSCSI, FC).

• New driver features were added, notably, Fujitsu ETERNUS DX extend volume on RAID group, Pure Storage synchronous replication, NetApp iSCSI LUN space allocation, Dell PowerFlex Active-Active support, Dell PowerMax configurable SRDF snapshots.

• Designate now supports Catalog Zones (RFC 9432). This can improve the scalability of Designate pools managing a large number of zones and significantly reduce the provisioning time when adding additional DNS servers to a Designate pool.

• Horizon now uses Django 4.2 as default and dropped Django 3.2 support.

• Ironic has enabled RBAC support by default by changing the default values of [oslo_policy]enforce_scope and [oslo_policy]enforce_new_defaults to True. Additionally, we added [DEFAULT]rbac_service_project_name to define a project where users in that project are treated as having a service role. Please see Ironic release notes for full details.

• Ironic has added the ability to drain active tasks from a conductor before shutdown. Sending a SIGUSR2 signal to an ironic-conductor will now attempt to complete running tasks with a timeout of [DEFAULT]drain_shutdown_timeout. No new tasks will be started on the conductor while it’s draining.

• Support was added for the external-gateway-multihoming API extension. The L3 service plugins supporting it can now create multiple gateway ports per router. It is currently limited to the L3 OVN plugin.

OpenStack Caracal is marked as Skip Level Upgrade Release Process or SLURP. According to this model (https://governance.openstack.org/tc/resolutions/20220210-release-cadence-adjustment.html) this means that upgrades will only be supported from the Antelope 2023.1 release.

RDO Caracal 2024.1 has been built and tested with the recently released Ceph  18.2.0 Reef version (https://docs.ceph.com/en/latest/releases/reef/)  which has been published by the CentOS Storage SIG in the official CentOS repositories. *Note:* Follow the instructions in [RDO documentation](https://www.rdoproject.org/install/install-with-ceph/) to install OpenStack and Ceph services in the same host.

The Next Release Cycle

At the end of one release, focus shifts immediately to the next release i.e Dalmatian.

Get Started

To spin up a proof of concept cloud, quickly, and on limited hardware, try an All-In-One Packstack installation. You can run RDO on a single node to get a feel for how it works.

For those that do not have any hardware or physical resources, there is the OpenStack Global Passport Program. This is a collaborative effort between OpenStack public cloud providers to let you experience the freedom, performance and interoperability of open source infrastructure. You can quickly and easily gain access to OpenStack infrastructure via trial programs from participating OpenStack public cloud providers around the world.

Get Help

The RDO Project has our users@lists.rdoproject.org for RDO-specific users and operators. For more developer-oriented content we recommend joining the dev@lists.rdoproject.org mailing list. Remember to post a brief introduction about yourself and your RDO story. The mailing lists archives are all available at https://mail.rdoproject.org. You can also find extensive documentation on RDOproject.org.

The #rdo channel on OFTC IRC is also an excellent place to find and give help.

We also welcome comments and requests on the CentOS devel mailing list and the CentOS IRC channels (#centos, #centos-cloud, #centos-devel in Libera.Chat network), however we have a more focused audience within the RDO venues.

Get Involved

To get involved in the OpenStack RPM packaging effort, check out the RDO contribute pages, peruse the CentOS Cloud SIG page, and inhale the RDO packaging documentation.

Join us in #rdo and on the OFTC IRC network and follow us on Twitter @RDOCommunity. You can also find us on Facebook and YouTube.
