Batch Support for CentOS 7 Ending

[alfpark]

Summary

Azure Batch will retire support for CentOS 7 aligned operating systems to follow the publisher ending standard support on June 30, 2024. If your workload utilizes Batch pools based on this OS, either via Marketplace images (directly from OpenLogic/RogueWave/Perforce/microsoft-azure-batch or derived from by other publishers) or your own custom images including compute image gallery, then you will need to take action. Please migrate your workload to a publisher supported version of an Enterprise Linux or derivative VM image such as Red Hat Enterprise Linux (RHEL), or AlmaLinux. On 2024-07-01, Azure Batch will remove support for the batch.node.centos 7 compute node agent. Afterwards, create pool and resize up operations for associated pools may fail. Customers who continue to use these pools past the indicated Batch support End of Life will be subject to potential security risks.

Migration possibilities

Please note that any Batch pool specifying the batch.node.centos 7 node agent is subject to end of life.
