End of life operating systems
-
Beginning with Jenkins 2.407, May 30, 2023, Jenkins administrators running a Jenkins weekly release will be warned if they are running Jenkins on an operating system that is within 6 months of its end of life date. The same warning will be visible to Jenkins administrators running a Jenkins long term support (LTS) release with the next LTS baseline after Jenkins 2.401.x, beginning August 23, 2023.
The warning includes the date when Jenkins will no longer be supported on that operating system version. It advises the administrator to upgrade to a newer version of the operating system.
Our Linux support policy states that the Jenkins project does not support, test, or accept pull requests for operating systems that are no longer supported by their provider.
Red Hat Enterprise Linux 7 and derivatives
Red Hat maintains Red Hat Enterprise Linux in accordance with the Red Hat Enterprise Linux Life Cycle. Red Hat Enterprise Linux 7 was initially released in 2014. It has been a very popular operating system thanks to its stability and long support life. That support life ends on June 30, 2024. A Red Hat blog post provides more details on the upcoming end of life.
Derivatives of Red Hat Enterprise Linux 7 like CentOS Linux 7, Scientific Linux 7, and Oracle Linux 7 will also no longer be supported after June 30, 2024. A CentOS project blog post shares their announcement of end of life.
The Jenkins project has decided to end its support of Red Hat Enterprise Linux 7 in late 2023 rather than waiting until 2024. After Nov 16, 2023, the Jenkins project will no longer support running Jenkins on Red Hat Enterprise Linux 7 or its derivatives. Jenkins container images based on CentOS 7 will no longer be supported after Nov 16, 2023.
Users should replace their Red Hat Enterprise Linux 7 installations with another operating system. If they prefer to continue with Red Hat or one of its derivatives, they have many alternatives, including:
-
Red Hat Enterprise Linux 8 or 9
-
AlmaLinux 8 or 9
-
Rocky Linux 8 or 9
-
Oracle Linux 8 or 9
