Redis Enterprise for Kubernetes release notes 6.4.2-4 (March 2023)

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 <b>not</b> 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.

\* Support added in this release

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 a version earlier than 6.2.10-45, you cannot upgrade directly to this release. You must upgrade to 6.2.10-45 before you can upgrade to versions 6.2.18 or later.

* **ValidatingWebhookConfiguration**

  This release uses a new `ValidatingWebhookConfiguration` resource to replace the `redb-admission` webhook resource. To use releases 6.4.2-4 or later, delete the old webhook resource and apply the new file. See [upgrade Redis cluster]() for instructions.

Active-Active preview known limitations

* No support for Hashicorp Vault for storing secrets (RED-95805)
* No module support (RED-95153)
* No support for client certificates in secrets (RED-95724)
* No support for backup configuration (RED-95724)
* No support for upgrading the database Redis version
* REAADB secret status isn't updated in source cluster (RED-96296)

  The workaround is to view the secret status in one of the remote clusters.
* Invalid REAADB is not rejected by admission might get deleted after apply. (RED-96300)

  Fix the problems with the REAADB and reapply. Contact support if you aren't sure why the REAADB is invalid.
* Admission is not blocking REAADB with `shardCount` which exceeds license quota. (RED-96301)

  Fix the problems with the REAADB and reapply.
* RERC resources must have a unique name (`<rec-name>/<rec-namespace>`). (RED-96302)

* Only global database options are supported, not support for specifying configuration per location.
* Can't automatically update the cluster secret via the operator (can be updated manually).
* No support for migration from old (manual) Active-Active database method to new Active-Active controller.

Known limitations

* REC creation might fail using form view on OpenShift. (RED-100517)

  To avoid this, use the YAML view. This will be fixed in the next release.

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. (RED-93025)

* Resharding fails for rack-aware databases with no replication (RED-97971)

  When a database is configured as [rack-aware]() and replication is turned off, the resharding operation fails.

  Workaround:
    Before resharding your database, [turn off rack awareness](). Set the `spec.rackAware` field in your REDB custom resource to `false`.
    After the resharding process is complete, you can [re-enable rack awareness]().

* Long cluster names cause routes to be rejected  (RED-25871)

  A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer.
* Cluster CR (REC) errors are not reported after invalid updates (RED-25542)

  A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.
* An unreachable cluster has status running (RED-32805)

  When a cluster is in unreachable state, the state remains `running` instead of triggering an error.
* Readiness probe incorrect on failures (RED-39300)

  STS Readiness probe does not mark a node as "not ready" when running `rladmin status` on node failure.
* Internal DNS and Kubernetes DNS may have conflicts (RED-37462)

  DNS conflicts are possible between the cluster `mdns_server` and the K8s DNS. This only impacts DNS resolution from within cluster nodes for Kubernetes DNS names.
* 5.4.10 negatively impacts 5.4.6 (RED-37233)

  Kubernetes-based 5.4.10 deployments seem to negatively impact existing 5.4.6 deployments that share a Kubernetes cluster.
* Node CPU usage is reported instead of pod CPU usage (RED-36884)

  In Kubernetes, the reported node CPU usage is the usage of the Kubernetes worker node hosting the REC pod.
* Clusters must be named "rec" in OLM-based deployments (RED-39825)

  In OLM-deployed operators, the deployment of the cluster will fail if the name is not "rec". When the operator is deployed via the OLM, the security context constraints (scc) are bound to a specific service account name (namely, "rec"). The workaround is to name the cluster "rec".
* REC clusters fail to start on Kubernetes clusters with unsynchronized clocks (RED-47254)

  When REC clusters are deployed on Kubernetes clusters with unsynchronized clocks, the REC cluster does not start correctly. The fix is to use NTP to synchronize the underlying K8s nodes.
* Deleting an OpenShift project with an REC deployed may hang (RED-47192)

  When an REC cluster is deployed in a project (namespace) and has REDB resources, the REDB resources must be deleted first before the REC can be deleted. Therefore, until the REDB resources are deleted, the project deletion will hang. The fix is to delete the REDB resources first and the REC second. Then, you can delete the project.
* Hashicorp Vault integration - no support for Gesher (RED-55080)

  There is no workaround at this time.
* REC might report error states on initial startup (RED-61707)

  There is no workaround at this time except to ignore the errors.
* PVC size issues when using decimal value in spec (RED-62132)

  The workaround for this issue is to make sure you use integer values for the PVC size.
* Following the previous quick start guide version causes issues with creating an REDB due to unrecognized memory field name (RED-69515)

  The workaround is to use the newer (current) revision of the [quick start]().
* `autoUpgrade` set to `true` can cause unexpected bdb upgrades when `redisUpgradePolicy` is set to `true` (RED-72351)

  Contact support if your deployment is impacted.

Breaking changes

The following changes included in this release affect the upgrade process. Please read carefully before upgrading to 7.2.4-12.

#### Upgrade operating system

If your databases use modules, you need to update all nodes in the cluster to Redis Enterprise 7.2.4 or later before upgrading your operating system. See [Upgrade a cluster's operating system]()in the Redis Enterprise Software documentation for more details.

#### terminationGracePeriodSeconds

The configurable `terminationGracePeriodSeconds` REC field has been added to replace the hard-coded timeout of 15 minutes for a node to be stopped/drained (RED-111471).

#### ValidatingWebhookConfiguration

Versions 6.4.2-4 and later include a new `ValidatingWebhookConfiguration` resource to replace the `redb-admission` webhook resource. To use releases 6.4.2-4 or later, delete the old webhook resource and apply the new file. See [upgrade Redis cluster]() for instructions.

#### OpenShift SCC

Versions 6.4.2-6 and later include a new SCC (`redis-enterprise-scc-v2`) that you need to bind to your service account before upgrading. OpenShift clusters running version 6.2.12 or earlier upgrading to version 6.2.18 or later might get stuck if you skip this step. See [upgrade a Redis Enterprise cluster (REC)]() for instructions.

Upcoming changes

- **Clusters must be named 'rec' in OLM-based deployments (RED-39825)** In OLM-deployed operators, the deployment of the cluster will fail if the name is not "rec". When the operator is deployed via the OLM, the security context constraints (scc) are bound to a specific service account name (namely, "rec"). The workaround is to name the cluster "rec".

- **Readiness probe incorrect on failures (RED-39300)** STS Readiness probe does not mark a node as "not ready" when running `rladmin status` on node failure.

- **Internal DNS and Kubernetes DNS may have conflicts (RED-37462)** DNS conflicts are possible between the cluster `mdns_server` and the K8s DNS. This only impacts DNS resolution from within cluster nodes for Kubernetes DNS names.

- **K8s-based 5.4.10 clusters seem to negatively affect existing 5.4.6 clusters (RED-37233)** Upgrade clusters to the latest version.

- **Node CPU usage is reported instead of pod CPU usage (RED-36884)** In Kubernetes, the reported node CPU usage is the usage of the Kubernetes worker node hosting the REC pod.

- **An unreachable cluster has status running (RED-32805)** When a cluster is in an unreachable state, the state remains `running` instead of triggering an error.

- **Long cluster names cause routes to be rejected  (RED-25871)** A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer.

- **Cluster CR (REC) errors are not reported after invalid updates (RED-25542)** A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.

Redis Enterprise for Kubernetes release notes 7.2.4-2 (Aug 2023)

Summary: The primary purpose this release is supporting Redis Enterprise 7.2.4.

Highlights

The primary purpose this release is supporting [Redis Enterprise 7.2.4](), which is a major Redis Enterprise Software update. As such, we reduced the scope of changes to support the underlying change of RS 7.2 and a few significant fixes.

The following are the notable changes:

- Support for [Redis Enterprise 7.2.4]()

    - New major version of Redis, 7.2
    - [Changes to modules and cluster recovery]()

Redis Enterprise Software 7.2.4-52 includes several issues that also effect Redis Enterprise for Kubernetes and are not listed below. Review the Redis Enterprise Software 7.2.4 [breaking changes]() and [known limitations.]()

- New default engine, Speedb, for Auto Tiering (formerly Redis on Flash)

- Changes to [supported Kubernetes distributions]()

New in this release

Enhancements

- Support for [Redis Enterprise 7.2.4]() (RED-73681)
- New default engine, Speedb, for Auto Tiering (formerly Redis on Flash) (RED-90850)
- Security context hardening (RED-98447)

Resolved issues

- Fixed: Services or routes from the Active-Active setup might not be removed (RED-77752)
- Fixed: Admission controller may not alert when patching the REAADB with missing secret or RERC (RED-104463)

API changes

The following fields were added to the RedisEnterpriseCluster (REC) custom resource definition (CRD):

- Added `status.BundledDatabaseRedisVersions.major` as a Boolean field indicating whether the Redis version is major.
- Added `spec.RedisOnFlashSpec.bigStoreDriver` to indicate the storage engine used for Auto Tiering (formerly Redis on Flash).

Version changes

For a list of fixes related to CVEs, see the [Redis Enterprise 7.2.4-52 release notes]().

Breaking changes

The following changes included in this release affect the upgrade process. Please read carefully before upgrading to 7.2.4-2.

#### ValidatingWebhookConfiguration

Versions 6.4.2-4 and later include a new `ValidatingWebhookConfiguration` resource to replace the `redb-admission` webhook resource. To use releases 6.4.2-4 or later, delete the old webhook resource and apply the new file. See [upgrade Redis cluster]() for instructions.

#### OpenShift SCC

Versions 6.4.2-6 and later include a new SCC (`redis-enterprise-scc-v2`) that you need to bind to your service account before upgrading. OpenShift clusters running version 6.2.12 or earlier upgrading to version 6.2.18 or later might get stuck if you skip this step. See [upgrade a Redis Enterprise cluster (REC)]() for instructions.

Deprecations

- Gesher (advanced admission control configuration support) previously deprecated, is no longer supported.
- Deprecated `spec.RedisOnFlashSpec.flashStorageEngine` field for the RedisEnterpriseCluster. Use `bigStoreDriver` field to indicate storage engines going forward.

Supported distributions

The following table shows supported distributions at the time of this release. You can also find this list in [Supported Kubernetes distributions]().

✅ Supported – This distribution is supported for this version of Redis Enterprise Software for Kubernetes.

⚠ Deprecated – This distribution is still supported for this version of Redis Enterprise Software for Kubernetes, but support will be removed in a future release.

- **Services Rigger**: `registry.connect.redhat.com/redislabs/services-manager:7.2.4-2`

#### OLM bundle

**Redis Enterprise operator bundle** : `v7.2.4-2`

It is not possible to upgrade your OLM deployment to version 7.2.4 from version 6.2.4-8 (November release). Uninstall 6.2.4-8 and perform a fresh install of 7.2.4.

Known limitations

The limitations below are specific to the Redis Enterprise for Kubernetes product. To view limitations for the supported Redis Enterprise Software version, see the [7.2.4 release notes]().

New limitations

- **REDBs created with versions before 6.2.10-4 will automatically upgrade modules when the cluster is upgraded (RED-106834)**

- **Cannot upgrade or recover clusters if there are databases with manually uploaded modules (RED-107711 RED-106872)** Contact support.

In version 7.2.4, old module versions and manually uploaded modules are not persisted. If databases are not upgraded after cluster upgrade, and require cluster recovery afterwards, you'll need to contact Redis support. This issue will be fixed in the next maintenance release by moving the stored location of the modules.

- **When modifying the database suffix for an Active-Active database, while the service-rigger is in a terminating state, the services-rigger will detele and create the ingress or route resources in a loop (RED-107687)** Wait until the services- rigger pod has finished to terminate it.

Existing limitations

- **REAADB changes might fail with "gateway timeout" errors, mostly on OpenShift (RED-103048)** Retry the operation.

- **Misleading error appears when a service creation has failed due to service already existing "`provided IP is already allocated`" (RED-100669)** Delete the service manually.

- **Existing OpenShift route during REC creation might prevent REC from starting (RED-100668)** Delete the route manually.

- **Creating two databases with the same name directly on Redis Enterprise software will cause the service to be deleted and the database will not be available (RED-99997)** Avoid duplicating database names. Database creation via K8s has validation in place to prevent this.

- **Installing the operator bundle produces warning: `Warning: would violate PodSecurity "restricted: v1.24"` (RED-97381)** Ignore the warning. This issue is documented as benign on official Red Hat documentation.

- **RERC resources must have a unique name (RED-96302)** The string "rec-name"/"rec-namespace" must be different from all other participating clusters in the Active-Active database.

- **Admission is not blocking REAADB with `shardCount` which exceeds license quota (RED-96301)** Fix the problems with the REAADB and reapply.

- **Active-Active controller only supports global database options. Configuration specific to location is not supported (RED-86490)**

- **Active-Active setup removal might keep services or routes undeleted (RED-77752)** Delete services or routes manually if you encounter this problem.

- **`autoUpgrade` set to `true` can cause unexpected bdb upgrades when `redisUpgradePolicy` is set to `true` (RED-72351)** Contact support if your deployment is impacted.

- **Following the previous quick start guide version causes issues with creating an REDB due to unrecognized memory field name (RED-69515)** The workaround is to use the newer (current) revision of Deploy Redis Enterprise Software for Kubernetes.

- **PVC size issues when using decimal value in spec (RED-62132)** Make sure you use integer values for the PVC size.

- **REC might report error states on initial startup (RED-61707)** There is no workaround at this time except to ignore the errors.

- **Hashicorp Vault integration - no support for Gesher (RED-55080)** There is no workaround for this issue. Gesher support has been deprecated.

- **REC clusters fail to start on Kubernetes clusters with unsynchronized clocks (RED-47254)** When REC clusters are deployed on Kubernetes clusters without synchronized clocks, the REC cluster does not start correctly. The fix is to use NTP to synchronize the underlying K8s nodes.

- **Deleting an OpenShift project with an REC deployed may hang (RED-47192)** When an REC cluster is deployed in a project (namespace) and has REDB resources, the REDB resources must be deleted first before the REC can be deleted. Therefore, until the REDB resources are deleted, the project deletion will hang. The fix is to delete the REDB resources first and the REC second. Then, you can delete the project.

- **Clusters must be named 'rec' in OLM-based deployments (RED-39825)** In OLM-deployed operators, the deployment of the cluster will fail if the name is not "rec". When the operator is deployed via the OLM, the security context constraints (scc) are bound to a specific service account name (namely, "rec"). The workaround is to name the cluster "rec".

- **Readiness probe incorrect on failures (RED-39300)** STS Readiness probe does not mark a node as "not ready" when running `rladmin status` on node failure.

- **Internal DNS and Kubernetes DNS may have conflicts (RED-37462)** DNS conflicts are possible between the cluster `mdns_server` and the K8s DNS. This only impacts DNS resolution from within cluster nodes for Kubernetes DNS names.

- **K8s-based 5.4.10 clusters seem to negatively affect existing 5.4.6 clusters (RED-37233)** Upgrade clusters to latest version.

- **Node CPU usage is reported instead of pod CPU usage (RED-36884)** In Kubernetes, the reported node CPU usage is the usage of the Kubernetes worker node hosting the REC pod.

- **An unreachable cluster has status running (RED-32805)** When a cluster is in an unreachable state, the state remains `running` instead of triggering an error.

- **Long cluster names cause routes to be rejected  (RED-25871)** A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer.

- **Cluster CR (REC) errors are not reported after invalid updates (RED-25542)** A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.


Redis Enterprise for Kubernetes release notes 7.2.4-7 (Oct 2023)

- **Existing OpenShift route during REC creation might prevent REC from starting (RED-100668)** Delete the route manually.

- **Creating two databases with the same name directly on Redis Enterprise software will cause the service to be deleted and the database will not be available (RED-99997)** Avoid duplicating database names. Database creation via K8s has validation in place to prevent this.

- **Installing the operator bundle produces warning: `Warning: would violate PodSecurity "restricted: v1.24"` (RED-97381)** Ignore the warning. This issue is documented as benign on official Red Hat documentation.

- **RERC resources must have a unique name (RED-96302)** The string "rec-name"/"rec-namespace" must be different from all other participating clusters in the Active-Active database.

- **Admission is not blocking REAADB with `shardCount` which exceeds license quota (RED-96301)** Fix the problems with the REAADB and reapply.

- **Active-Active controller only supports global database options. Configuration specific to location is not supported (RED-86490)**

- **Active-Active setup removal might keep services or routes undeleted (RED-77752)** Delete services or routes manually if you encounter this problem.

- **`autoUpgrade` set to `true` can cause unexpected bdb upgrades when `redisUpgradePolicy` is set to `true` (RED-72351)** Contact support if your deployment is impacted.

- **Following the previous quick start guide version causes issues with creating an REDB due to unrecognized memory field name (RED-69515)** The workaround is to use the newer (current) revision of Deploy Redis Enterprise Software for Kubernetes.

- **PVC size issues when using decimal value in spec (RED-62132)** Make sure you use integer values for the PVC size.

- **REC might report error states on initial startup (RED-61707)** There is no workaround at this time except to ignore the errors.

- **Hashicorp Vault integration - no support for Gesher (RED-55080)** There is no workaround for this issue. Gesher support has been deprecated.

- **REC clusters fail to start on Kubernetes clusters with unsynchronized clocks (RED-47254)** When REC clusters are deployed on Kubernetes clusters without synchronized clocks, the REC cluster does not start correctly. The fix is to use NTP to synchronize the underlying K8s nodes.

- **Deleting an OpenShift project with an REC deployed may hang (RED-47192)** When an REC cluster is deployed in a project (namespace) and has REDB resources, the REDB resources must be deleted first before the REC can be deleted. Therefore, until the REDB resources are deleted, the project deletion will hang. The fix is to delete the REDB resources first and the REC second. Then, you can delete the project.

- **Clusters must be named 'rec' in OLM-based deployments (RED-39825)** In OLM-deployed operators, the deployment of the cluster will fail if the name is not "rec". When the operator is deployed via the OLM, the security context constraints (scc) are bound to a specific service account name (namely, "rec"). The workaround is to name the cluster "rec".

- **Readiness probe incorrect on failures (RED-39300)** STS Readiness probe does not mark a node as "not ready" when running `rladmin status` on node failure.

- **Internal DNS and Kubernetes DNS may have conflicts (RED-37462)** DNS conflicts are possible between the cluster `mdns_server` and the K8s DNS. This only impacts DNS resolution from within cluster nodes for Kubernetes DNS names.

- **K8s-based 5.4.10 clusters seem to negatively affect existing 5.4.6 clusters (RED-37233)** Upgrade clusters to latest version.

- **Node CPU usage is reported instead of pod CPU usage (RED-36884)** In Kubernetes, the reported node CPU usage is the usage of the Kubernetes worker node hosting the REC pod.

- **An unreachable cluster has status running (RED-32805)** When a cluster is in an unreachable state, the state remains `running` instead of triggering an error.

- **Long cluster names cause routes to be rejected  (RED-25871)** A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer.

- **Cluster CR (REC) errors are not reported after invalid updates (RED-25542)** A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.


7.2.4 release notes

Summary: Support for Redis Enterprise 7.2.4, platform support updates, and bug fixes.

Highlights

The primary purpose this release is supporting [Redis Enterprise 7.2.4](), which is a major Redis Enterprise Software update. As such, we reduced the scope of changes to support the underlying change of RS 7.2 and a few significant fixes.

The following are the notable changes:

- Support for [Redis Enterprise 7.2.4]()

    - New major version of Redis, 7.2
    - [Changes to modules and cluster recovery]()

Redis Enterprise Software 7.2.4-52 includes several issues that also effect Redis Enterprise for Kubernetes and are not listed below. Review the Redis Enterprise Software 7.2.4 [breaking changes]() and [known limitations.]()

Detailed release notes

Version changes

For a list of fixes related to CVEs, see the [Redis Enterprise 7.2.4 release notes]().

Breaking changes

The following changes included in this release affect the upgrade process. Please read carefully before upgrading to 7.2.4-2.

#### ValidatingWebhookConfiguration

Versions 6.4.2-4 and later include a new `ValidatingWebhookConfiguration` resource to replace the `redb-admission` webhook resource. To use releases 6.4.2-4 or later, delete the old webhook resource and apply the new file. See [upgrade Redis cluster]() for instructions.

#### OpenShift SCC

Versions 6.4.2-6 and later include a new SCC (`redis-enterprise-scc-v2`) that you need to bind to your service account before upgrading. OpenShift clusters running version 6.2.12 or earlier upgrading to version 6.2.18 or later might get stuck if you skip this step. See [upgrade a Redis Enterprise cluster (REC)]() for instructions.

Deprecations

- Gesher (advanced admission control configuration support) previously deprecated, is no longer supported.
- Deprecated `spec.RedisOnFlashSpec.flashStorageEngine` field for the RedisEnterpriseCluster. Use `bigStoreDriver` field to indicate storage engines going forward.

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

Summary: Feature release with Redis Software 7.22.0-28 support, enhancements, and platform updates.

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](). 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](). |
| REC | `spec.securityContext.resourceLimits` | Added | Configuration that allows Redis Enterprise to adjust system resource settings. For details, see the [REC API reference](). |

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]().

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](https://redis.io/docs/latest/operate/kubernetes/7.4.6/upgrade/).
- Database version 7.2 or later.
- RHEL9 compatible binaries for any modules you need.

For detailed steps, see the relevant upgrade page:

- [OpenShift CLI]()
- [OpenShift OperatorHub]()
- [Kubernetes]()

Known limitations

- **Only upgrades from 7.4.2-2 and later are supported.** If you are using an earlier version, install 7.4.2-2 before upgrading to 7.8.2-6 or later.

- **When changing the REDB field `spec.modulesList`, version might be upgraded to latest, even if a different version is specified.** To prevent the upgrade to latest, set  `spec.upgradeSpec.setModuleToLatest` to `false` before upgrading.

- **PVC expansion is not supported when using Redis on Flash (Auto Tiering) (RED-165770)** Do not enable `enablePersistentVolumeResize` if your REC uses `redisOnFlashSpec` as this will result in conflicts.

- **Istio ingress does not support partial wildcard hostnames** When using Istio ingress for Redis on Kubernetes, avoid partial wildcard hostnames in your REC configuration. Use only valid FQDNs or leftmost wildcards for Istio compatibility and stable external routing. For more information, see [Istio Ingress Fails for Redis on Kubernetes with Partial Wildcard Hostnames](https://support.redislabs.com/hc/en-us/articles/30446436267666-Istio-Ingress-Fails-for-Redis-on-Kubernetes-with-Partial-Wildcard-Hostnames).

- **Missing endpoint for admission endpoint (rare) (RED-119469)** Restart the operator pod.

- **The REDB "redisVersion" field can’t be used for memcached databases(RED-119152)**

- **When modifying the database suffix for an Active-Active database, while the service-rigger is in a terminating state, the services-rigger will delete and create the ingress or route resources in a loop (RED-107687)** Wait until the services rigger pod has finished to terminate it.

- **REAADB changes might fail with "gateway timeout" errors, mostly on OpenShift (RED-103048)** Retry the operation.

- **Creating two databases with the same name directly on Redis Enterprise software will cause the service to be deleted and the database will not be available (RED-99997)** Avoid duplicating database names. Database creation via K8s has validation in place to prevent this.

- **Installing the operator bundle produces warning: `Warning: would violate PodSecurity "restricted: v1.24"` (RED-97381)** Ignore the warning. This issue is documented as benign on official Red Hat documentation.

- **RERC resources must have a unique name (RED-96302)** The string "rec-name"/"rec-namespace" must be different from all other participating clusters in the Active-Active database.

- **Admission is not blocking REAADB with `shardCount` which exceeds license quota (RED-96301)** Fix the problems with the REAADB and reapply.

- **Active-Active controller only supports global database options. Configuration specific to location is not supported (RED-86490)**

- **Active-Active setup removal might keep services or routes undeleted (RED-77752)** Delete services or routes manually if you encounter this problem.

- **`autoUpgrade` set to `true` can cause unexpected bdb upgrades when `redisUpgradePolicy` is set to `true` (RED-72351)** Contact support if your deployment is impacted.

- **Following the previous quick start guide version causes issues with creating an REDB due to unrecognized memory field name (RED-69515)** The workaround is to use the newer (current) revision of Deploy Redis Enterprise Software for Kubernetes.

- **PVC size issues when using decimal value in spec (RED-62132)** Make sure you use integer values for the PVC size.

- **REC might report error states on initial startup (RED-61707)** There is no workaround at this time except to ignore the errors.

- **Hashicorp Vault integration - no support for Gesher (RED-55080)** There is no workaround for this issue. Gesher support has been deprecated.

- **REC clusters fail to start on Kubernetes clusters with unsynchronized clocks (RED-47254)** When REC clusters are deployed on Kubernetes clusters without synchronized clocks, the REC cluster does not start correctly. The fix is to use NTP to synchronize the underlying K8s nodes.

- **Deleting an OpenShift project with an REC deployed may hang (RED-47192)** When an REC cluster is deployed in a project (namespace) and has REDB resources, the REDB resources must be deleted first before the REC can be deleted. Therefore, until the REDB resources are deleted, the project deletion will hang. The fix is to delete the REDB resources first and the REC second. Then, you can delete the project.

- **Clusters must be named 'rec' in OLM-based deployments (RED-39825)** In OLM-deployed operators, the deployment of the cluster will fail if the name is not "rec". When the operator is deployed via the OLM, the security context constraints (scc) are bound to a specific service account name (namely, "rec"). The workaround is to name the cluster "rec".

- **Readiness probe incorrect on failures (RED-39300)** STS Readiness probe does not mark a node as "not ready" when running `rladmin status` on node failure.

- **Internal DNS and Kubernetes DNS may have conflicts (RED-37462)** DNS conflicts are possible between the cluster `mdns_server` and the K8s DNS. This only impacts DNS resolution from within cluster nodes for Kubernetes DNS names.

- **K8s-based 5.4.10 clusters seem to negatively affect existing 5.4.6 clusters (RED-37233)** Upgrade clusters to latest version.

- **Node CPU usage is reported instead of pod CPU usage (RED-36884)** In Kubernetes, the reported node CPU usage is the usage of the Kubernetes worker node hosting the REC pod.

- **An unreachable cluster has status running (RED-32805)** When a cluster is in an unreachable state, the state remains `running` instead of triggering an error.

- **Long cluster names cause routes to be rejected  (RED-25871)** A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer.

- **Cluster CR (REC) errors are not reported after invalid updates (RED-25542)** A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.

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](https://redis.io/docs/latest/operate/kubernetes/7.4.6/upgrade/).
- Database version 7.2 or later.
- RHEL9 compatible binaries for any modules you need.

For detailed steps, see the relevant upgrade page:

- [OpenShift CLI]()
- [OpenShift OperatorHub]()
- [Kubernetes]()


Redis Enterprise for Kubernetes 7.4.2-2 (March 2024) release notes

Summary: This is a maintenance release supporting Redis Enterprise Software 7.4.2.

Highlights

The primary purpose of this release is to support [Redis Enterprise 7.4.2](), which is a maintenance release of Redis Enterprise Software.

Version changes

For a list of fixes related to CVEs, see the [Redis Enterprise 7.4.2-104 release notes]().

Breaking changes

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

#### Upgrade operating system

If your databases use modules, you need to update all nodes in the cluster to Redis Enterprise 7.2.4 or later before upgrading your operating system. See [Upgrade a cluster's operating system]()in the Redis Enterprise Software documentation for more details.

#### terminationGracePeriodSeconds

The configurable `terminationGracePeriodSeconds` REC field was added in version 7.2.4-12 to replace the hard-coded timeout of 15 minutes for a node to be stopped or drained (RED-111471).

#### ValidatingWebhookConfiguration

Versions 6.4.2-4 and later include a new `ValidatingWebhookConfiguration` resource to replace the `redb-admission` webhook resource. To use releases 6.4.2-4 or later, delete the old webhook resource and apply the new file. See [upgrade Redis cluster]() for instructions.

#### OpenShift SCC

Versions 6.4.2-6 and later include a new SCC (`redis-enterprise-scc-v2`) that you need to bind to your service account before upgrading. OpenShift clusters running version 6.2.12 or earlier upgrading to version 6.2.18 or later might get stuck if you skip this step. See [upgrade a Redis Enterprise cluster (REC)]() for instructions.

Deprecations

- Redis Software for Kubernetes no longer supports the RHEL7 operating system. Migrate to RHEL8 to use this version.

Supported distributions

See the [7.4.2 releases]() page for the list of supported distributions.
