This risk is ultimately entirely your responsibility. CERN IT does not offer any support beyond what is explicitly stated on this page."
Following the end-of-life of CC7 (30.06.2024) and through a special agreement with the Accelerator and Technology Sector, CERN IT will rebuild Red Hat's Extended Lifecycle Support (ELS) product to be consumable at CERN, for a limited duration of time. The specifics of this arrangement are as follows:
Following the end-of-life of CC7 (30.06.2024) and through a [special agreement with the Accelerator and Technology Sector](#what-is-the-atsit-cc7-agreement), CERN IT will rebuild Red Hat's Extended Lifecycle Support (ELS) product to be consumable at CERN, for a limited duration of time. ELS7 provides updates for some security vulnerabilities beyond the end-of-life of CC7 and may, in some cases, reduce the risk of running on an unsupported operating system.
* The managed [docker image](https://gitlab.cern.ch/linuxsupport/cc7-base) will continue to exist, however, it will not be updated after 30.06.2024. It's the responsibility of the service owner/user to ensure that CC7 containers running after 30.06.2024 continue to be secure. For this reason, new or updated CC7 containers should add the ELS7 repository to ensure that critical security updates can be included in the image
