What's Next After CentOS? AlmaLinux and RockyLinux Offer a Free Alternative

With the discontinuation of CentOS in its old form, two projects are vying to fill the gap: AlmaLinux and RockyLinux. But what does this mean for users who relied on CentOS as their go-to Docker base image? In this article, we'll explore the options available and help you find a suitable replacement.

For those unfamiliar, RockyLinux was started by one of the original creators of CentOS, while AlmaLinux is a product of CloudLinux, a commercial Linux vendor that previously based its product on CentOS. Both offer free images that are compatible with RHEL8, but which one should you choose?

AlmaLinux and Oracle Linux

AlmaLinux, maintained by CloudLinux, provides a free alternative to CentOS with the added benefit of commercial support if needed. On the other hand, Oracle Linux is a pre-existing clone of RedHat Enterprise Linux (RHEL), maintained by Oracle. Both options offer stability and long-term support.

RockyLinux: A New Kid on the Block

RockyLinux is another contender in the CentOS replacement landscape. Specifically designed to be compatible with RHEL8, it aims to provide a free image that is equivalent to the old CentOS. With its focus on backwards compatibility, long-term availability of security updates, and regular package additions, RockyLinux has all the makings of a great Docker base image.

RHEL 8: The Gold Standard

RedHat Enterprise Linux (RHEL) version 8 was released in May 2019 and will continue to receive full support until May 2024. Additionally, security updates will be available until May 2029. As such, RHEL 8 is an excellent choice for a Docker base image.

In conclusion, if you're looking for a stable, long-term-support base image that guarantees backwards compatibility and provides regular package additions, AlmaLinux, Oracle Linux, or RockyLinux are all viable options. With the discontinuation of CentOS in its old form, it's essential to explore these alternatives to ensure a seamless transition.

Remember, RHEL 8 is still supported until May 2029, making it an excellent choice for those who need a reliable Docker base image. Whether you choose AlmaLinux, Oracle Linux, or RockyLinux, rest assured that your containerized applications will continue to run smoothly with the support of these free images.
