## API changes

**CRD**

**Field**

**Change**

**Description**

REAADB

`spec.globalConfigurations.auditing`

Added

Enable database connection auditing.

REAADB

`spec.globalConfigurations.alertSettings`

Added

Configure alert settings for the active-active database.

REAADB

`spec.globalConfigurations.rofRamRatio`

Added

RAM allocation ratio for Redis Flex (v2) databases as a percentage of total data size. Valid range: 0-100. Default: 50% when omitted. Controls how much RAM is allocated per unit of data (for example, 30% means 3MB RAM per 10MB data). RAM grows proportionally with data until `rofRamSize` limit is reached (if specified). Only applicable when `isRof=true` and Redis version 8.0 or later (BigStore v2 - Redis Flex).

REC

`spec.auditing`

Added

Cluster-level configuration for auditing database connection and authentication events. Includes both the audit listener connection parameters and the default policy for new databases.

REC

`spec.sso`

Added

Cluster-level SSO configuration for authentication to the cluster manager UI.

REC

`spec.userDefinedModules`

Added

List of user-defined modules to be downloaded and installed during cluster bootstrap. The modules on the list will be downloaded on cluster creation, upgrade, scale-out, and recovery and installed on all nodes. Changing this field for a running cluster will trigger a rolling update.

REC

`spec.certificates.ssoServiceCertificateSecretName`

Added

Secret name for the cluster's SSO service certificate. Used for SAML-based SSO authentication to the cluster manager. The secret must contain `name`, `certificate`, and `key` fields (same format as other cluster certificates). If left blank, SSO will not be configured.

REC

`spec.certificates.ssoIssuerCertificateSecretName`

Added

Secret name for the SSO Identity Provider (IdP) certificate. This is the public certificate from your SAML Identity Provider used to verify SAML assertions. The secret must contain `name` and `certificate` fields (no `key` field needed for IdP certificate). This is optional - if using IdP metadata XML, the IdP certificate is included in the metadata.

REDB

`spec.auditing`

Added

Database-level auditing configuration.

REDB

`spec.rofRamRatio`

Added

RAM allocation ratio for Redis Flex (v2) databases as a percentage of total data size. Valid range: 0-100. Default: 50% when omitted. Controls how much RAM is allocated per unit of data (for example, 30% means 3MB RAM per 10MB data). RAM grows proportionally with data until `rofRamSize` limit is reached (if specified). Only applicable when `isRof=true` and Redis version 8.0 or later (BigStore v2 - Redis Flex).

REDB

`status.bigstoreVersion`

Added

BigStore version for Redis on Flash databases (1 for Auto Tiering, 2 for Redis Flex). Read-only field populated from Redis Software.

## Downloads

*   **Redis Enterprise**: `redislabs/redis:8.0.6-54`
*   **Operator**: `redislabs/operator:8.0.6-8`
*   **Services Rigger**: `redislabs/k8s-controller:8.0.6-8`
*   **Callhome client**: `redislabs/re-call-home-client:8.0.6-8`

### Openshift downloads

*   **OLM operator bundle**: `8.0.6-8.0`
*   **Call Home Client**: `redislabs/call-home-client:8.0.6-8`

## Known limitations

### New limitations

*   **SSO configuration doesn't work with IPv6 or dual stack (IPv4/IPv6) clusters.**

### Existing 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 8.0.6-8.
    
*   **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 in the Redis Enterprise cluster manager UI will cause the service to be deleted and the database will not be available (RED-99997)** Avoid duplicating database names. The admission controller prevents duplicate database names when databases are created via the Kubernetes operator.
    
*   **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.
