Redis Enterprise for Kubernetes 7.22.0-7 (April 2025) release notes

New in the release

Redis Enterprise for Kubernetes 7.22.0-7 is a feature release that includes enhancements, platform updates, and support for Redis Software 7.22.0-28.

Enhancements

• Added support for Redis Software 7.22.0.
• Enabled support for Active-Active databases (REAADB) in multi-namespace deployments.
• Defaulted new installations and upgrades to unprivileged mode, which uses a more secure security context without additional Linux capabilities.
• A new cronjob is created by the operator using the `redislabs/re-call-home-client.7.22.0-7 image.
• Updated supported Kubernetes platforms.

API changes

CRD	Field	Change	Description
REAADB	spec.participatingClusters[].namespace	Added	Specifies the namespace in which the REAADB object will be deployed in the corresponding participating cluster. Make sure that the Redis Enterprise operator is configured to watch this namespace and that the required RBAC configuration is in place. For more information, see [Multi-namespace deployments]({{<relref "/operate/kubernetes/re-clusters/multi-namespace/">}}). If no namespace is specified, the REAADB object is deployed to the REC’s namespace in the corresponding cluster.
REC	spec.usageMeter.callHomeClient	Added	Configuration for the call home client. For details, see the [REC API reference]({{<relref "/operate/kubernetes/reference/api/redis_enterprise_cluster_api">}}).
REC	spec.securityContext.resourceLimits	Added	Configuration that allows Redis Enterprise to adjust system resource settings. For details, see the [REC API reference]({{<relref "/operate/kubernetes/reference/api/redis_enterprise_cluster_api">}}).

Breaking changes

By default, the operator no longer sets additional Linux capabilities in the security context. If your deployment requires capabilities such as SYS_RESOURCE, see [Allow automatic resource adjustment]({{< relref "/operate/kubernetes/security/allow-resource-adjustment" >}}).

RHEL9-based image

As of version 7.8.2-6, Redis Enterprise images are based on Red Hat Enterprise Linux 9 (RHEL9). This means upgrades require:

• Cluster version of 7.4.2-2 or later.
• Database version 7.2 or later.
• RHEL9 compatible binaries for any modules you need.

For detailed steps, see the relevant upgrade page:

• [OpenShift CLI]({{<relref "/operate/kubernetes/upgrade/openshift-cli">}})
• [OpenShift OperatorHub]({{<relref "/operate/kubernetes/upgrade/upgrade-olm">}})
• [Kubernetes]({{<relref "/operate/kubernetes/upgrade/upgrade-redis-cluster" >}})
