RHEL9-based images
-
Redis Enterprise images are now based on Red Hat Enterprise Linux 9 (RHEL9). This means upgrades to 7.8.2-6 require:
-
Cluster version of 7.4.2-2 or later.
-
Database version 7.2 or later.
-
RHEL9 compatible binaries for any modules you need.
See Upgrade Redis Enterprise for Kubernetes for detailed steps to upgrade to 7.8.2-6.
Deprecations
- Ubuntu-based images are no longer supported.
- REDB field `upgradeSpec.upgradeModulesToLatest is deprecated.
- REDB field
spec.modulesList.version
is deprecated.

OLM operator bundle: v7.8.2-6.3
Known limitations
New 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.
-
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, setspec.upgradeSpec.setModuleToLatest
tofalse
before upgrading to 7.8.2-6.
Existing limitations
-
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 totrue
can cause unexpected bdb upgrades whenredisUpgradePolicy
is set totrue
(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. -

7.4.6-2
Highlights
The primary purpose of this release is to support Redis Enterprise Software version 7.4.6. It also includes updates to supported platform distributions.
New in this release
Enhancements
- Removal of multiple unneeded permissions from RBAC roles used by the operator (RED-123478 RED-125020)
- Support for non-AWS S3 compatible backup targets in REC (RED-73642)
- Support for Redis Enterprise 7.4.6-22 (RED-13110)
API changes
CRD | Field | Change | Description |
---|---|---|---|
REC | backup.s3.caCertificateSecretName | Add | Secret name that holds the S3 CA certificate, which contains the TLS certificate mapped to the key in the secret 'cert' |
REC | backup.s3.url | Add | Specifies the URL for S3 export and import (used for custom S3 compatible servers) |
Version changes
Breaking changes
The following changes included in this release affect the upgrade process. Please read carefully before upgrading.
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
- Future Redis Enterprise images will be UBI9-based only, without support for Ubuntu-based images.

7.4.2-2
Highlights
The primary purpose of this release is to support Redis Enterprise 7.4.2, which is a major update to Redis Enterprise Software. As such, we have limited the scope of changes to focus on supporting RS 7.4 changes, in addition to implementing a few enhancements and major fixes.
New in this release
Enhancements
- Added RESP3 support in K8s APIs (RED-94601)
- Added to supported distributions
- Added support for Redis Enterprise Software 7.4.2
- Enhanced resilience of operators to misconfigured REDB namespaces (RED-113908)
- Both the operator and services rigger are now based on UBI9 (RED-116083)
Resolved issues
- Fixed the operator to prevent reconciliation of non-REDB custom resources in observed namespaces. This eliminates the need for unnecessary permission rules. (RED-87790)
- Fixed excessive updates to ingresses and services. (RED-109289)
- Fixed update issues in rigger after the upgrade in multi-namespace environments. (RED-111732)
- Fixed Active-Active sharding configuration by adding a new field. (RED-112909)
- Fixed operator CVE. (RED-115157)
- Fixed a race condition that could have rarely caused the cluster upgrade to break. (RED-118940)

Version changes
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 systemin 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.

Version changes
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
- A future release of Redis Enterprise will remove support for RHEL7. We recommend migrating to RHEL8.

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.
Existing limitations
-
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 totrue
can cause unexpected bdb upgrades whenredisUpgradePolicy
is set totrue
(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.

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. -
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 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.

Before upgrading
Be aware the following changes included in this release affect the upgrade process. Please read carefully before upgrading to 6.4.2-6.
-
ValidatingWebhookConfiguration
This release uses a new
ValidatingWebhookConfiguration
resource to replace theredb-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
This release includes 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 details.
Known limitations
New 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.
Existing limitations
-
RERC resources must have a unique name (
<rec-name>/<rec-namespace>
) (RED-96302) -
Admission is not blocking REAADB with
shardCount
which exceeds license quota. (RED-96301) Fix the problems with the REAADB and reapply. -
Active-Active setup removal might keep services or routes undeleted (RED-77752) Delete services or routes manually if you encounter this problem.
-
autoUpgrade
set totrue
can cause unexpected bdb upgrades whenredisUpgradePolicy
is set totrue
(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 the [quick start]({{<relref "/kubernetes/deployment/quick-start.md">}}).
-
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 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.
