CentOS 8 EOL: Know Your Support Options

Operating Systems
Open Source

CentOS 8 end of life (EOL) arrived much sooner than anticipated. In December 2020, Red Hat announced that the CentOS 8 EOL date was being moved up to December 2021, shortening the expected community CentOS 8 support lifecycle by eight years.

For organizations using CentOS 8, that change sparked an immediate discussion about migration options, and/or alternative arrangements for CentOS 8 support. In this blog, we look at available LTS options for CentOS 8, and what the future looks like for those who want to stay on CentOS 8.

Original CentOS 8 End of Life Schedule

As Javier Perez mentioned in his recent blog on the CentOS announcement, the CentOS lifecycle specification historically followed two phases of long term support, “Full Updates,” and “Maintenance Updates.”

Full Updates

The “Full Updates” phase of CentOS community LTS started immediately upon release, and outlined 2-3 updates per year for 6 years following the release. These updates ranged from new hardware support to errata. After those 6 years were up, the version would then enter the “Maintenance Release” phase.

Maintenance Updates

Following the “Full Updates” phase, the “Maintenance Updates” phase provided only security errata critical bug fixes for the version. This phase would last for around 4 years, after which the version would enter end of life.

Updated CentOS 8 Schedule

After the announcement from the CentOS community and Red Hat, the CentOS 8 lifecycle was dramatically reduced. The “Full Updates” phase, initially planned run from 2019-2025, was changed to December of 2021. The “Maintenance Updates” phase, which was initially planned to run from 2025-2029, was eliminated entirely.

CentOS 8 EOL Support Options

With community CentOS 8 support ending in December, 2021, finding a replacement long term support option is an immediate concern for many organizations.

For some, that may mean reverting to upstream commercial vendor support via RHEL. For others, finding a 1:1 commercial support replacement will be the better option. For smaller organizations, or those with sufficient internal expertise, self-support may buy enough time for their next migration.

CentOS 8 Support From Vendors

When CentOS 8 reaches community support end of life in December, CentOS users who want CentOS 8 support from Red Hat will need to migrate to a supported RHEL version.

For those who migrate or “convert” to RHEL, the most common paths are horizontal, (e.g. CentOS 8 to RHEL 8). For those undertaking a migration, RHEL advises users to book consulting services.

For many organizations who left RHEL for CentOS due to pricing concerns, a move back to RHEL may not be in the budget -- and paying Red Hat for the pleasure of getting there may upset some stomachs.

For those who need to move back to RHEL and don’t want to pay Red Hat for help with their CentOS migration, OpenLogic can provide consultative guidance and migration planning services.

CentOS 8 Support From the Community

Community release support with new releases and patches, as noted above, would normally include the “Full Updates” and “Maintenance Updates”. This community release support will end in December 2021.

Of course, the community itself isn’t going away. People who have worked on CentOS Linux in the past will still exist and will still be around.

Will they still answer questions related to CentOS 8?

Considering many of the CentOS contributors work for Red Hat, probably not. The CentOS community is effectively moving on to CentOS Stream. Regardless, relying on un-defined community support isn’t feasible for most organizations unless they have an internal team with the expertise needed to backport or create patches and bug fixes.

CentOS 8 Commercial Support

For those who want to remain on CentOS 8 beyond December of 2021, finding extended technical support that provides backported patches and bug fixes is the best option.

This isn’t a permanent solution, of course. But for companies who have just performed a costly and/or time-consuming migration, performing another migration so soon may not be in the picture. For them, supporting their CentOS 8 implementations until they can plan for a migration will be the more cost-effective, albeit temporary, solution.

Finding a CentOS 8 Support Vendor

There are a handful of companies who provide long-term CentOS 8 support, including OpenLogic. Finding the best option requires companies to analyze their support needs.

Companies should start their search by determining their organizational needs. That begins with answering questions like:

  • What do they want their response to look like if there’s a notable CVE after CentOS 8 EOL?
  • How long will you need support?
  • Do you need support for more than just CentOS 8?
  • Do you need security-hardened builds?
  • Do you need the support to check a box for compliance, or do you want need experts that can actually help?
