6.2.18 release notes

Release notes for the 6.2.18 releases of Redis Enterprise Software for Kubernetes.

Before upgrading

Be aware the following changes included in this release affect the upgrade process. Please read carefully before upgrading.

Supported upgrade paths

If you are using operator version 6.2.8-15 or earlier, you cannot upgrade directly to operator versions 6.2.12 through 6.4.2-5. You must upgrade to operator version 6.2.10-45 before you can upgrade to operator versions between 6.2.12 and 6.4.2-5. However, upgrades directly to operator version 6.4.2-6 are supported.

OpenShift versions 6.2.12 or earlier

Due to a change in the SCC, on OpenShift clusters running version 6.2.12 or earlier upgrading to version 6.2.18 or later, where node:1 is not the master node, the upgrade might get stuck.

For more info and steps to prevent this issue, see upgrade a Redis Enterprise cluster (REC).

Operator version 6.4.2-6 includes a fix for this issue.

Large clusters

On clusters with more than 9 REC nodes, a Kubernetes upgrade can render the Redis cluster unresponsive in some cases. A fix is available in the 6.4.2-5 release. Upgrade your operator version to 6.4.2-5 or later before upgrading your Kubernetes cluster.
