title: Known limitations

title: New limitations

text: - **SSO configuration doesn't work with IPv6 or dual stack (IPv4/IPv6) clusters.** <!--RED-180550-->

title: Existing limitations

text:
- **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 8.0.10-21.

- **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.

title: Modules in Redis 8

text:
In Redis Enterprise databases created with or upgraded to Redis version 8 or later, bundled modules are enabled automatically, so you don't need to specify them in the `spec.moduleList` field. However, if you want to use a specific version of a bundled module, you can specify it in the `spec.moduleList` field.

The bundled capabilities (modules) are automatically enabled as follows:

| Database type | Automatically enabled capabilities |
|---------------|------------------------------------|
| RAM-only | [Search and query]()
[JSON]()
[Time series]()
[Probabilistic]()  |
| Flash-enabled ([Redis Flex]()) | [JSON]()
[Probabilistic]() |
| [Active-Active]() | [Search and query]()
[JSON]() |

For more information, see [Automatically enabled capabilities in Redis 8]().

title: Breaking changes

text:
- **Custom modules are not supported** with this version. Only the capabilities (modules) listed above are supported in this release. **If you use user-defined modules, don't upgrade to this version.** The Redis Enterprise version used with this operator version includes significant changes to modules, including using built-in modules by default on databases. For more details, see the Redis Software release notes.

- **TKG (TKG) is no longer supported**. Broadcom/VMware doesn't plan to support this platform in the near future. We recommend that you migrate to TKGI/VKS.

text:
- **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 8.0.2-2.

- **You must keep existing moduleList version numbers when upgrading redisVersion.** When upgrading a database's `redisVersion`, you must keep the existing module version numbers in `moduleList` unchanged. If you modify the module versions in `moduleList` during a `redisVersion` upgrade, the upgrade request will fail. The database will automatically use the bundled module versions for the new Redis version, regardless of what versions are specified in `moduleList`. This applies to both REDB and REAADB databases.

- **Custom certificate upload is not supported for internode encryption (RED-173229).** Internode communication between cluster nodes continues to use default self-signed certificates and cannot be configured with customer-provided certificates.

- **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)**

- **Database suffix changes during service-rigger termination cause resource recreation loops (RED-107687)** If you modify the database suffix for an Active-Active database while the service-rigger is in a terminating state, the service-rigger will continuously delete and recreate ingress or route resources. Wait until the services rigger pod has finished terminating before making suffix changes.

- **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.

- **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.

title: Detailed release notes

title: RHEL9-based image

text:
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]()

title: API changes

text:
| **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. |

title: Overview

text:
[Redis Enterprise for Kubernetes 5.4.10-8](https://github.com/RedisLabs/redis-enterprise-k8s-docs/releases/tag/5.4.10-8) is now available.
This release includes Redis Enterprise (RS) version [5.4.10-22]() and introduces new feature and bug fixes.

title: Overview

text:
This is a maintenance release providing support for the Redis Enterprise Software release 5.4.10 and includes multiple enhancements.

Follow these [instructions]() for upgrading to this Kubernetes operator release.

title: New features

text:
- All-in-one deployment bundle and documentation enhancements - This release is the easiest to deploy yet, with a new quick start guide and an all-in-one file bundle for deploying the Redis Enterprise Operator. GitHub documentation was enhanced to cover advanced deployment scenarios with the complete reference to the custom resource specifications, guides, and examples.

    Pay special attention to the yaml file naming changes and new yaml files that have been created for this release. These are highlighted in the quick start guide.

- Rack Awareness - Support for the [Redis Software Rack Awareness][] feature was introduced to the Kubernetes deployment. It enables deploying nodes to different zones, in a multi-zone Kubernetes cluster. Databases that are rack-aware will have the cluster populate their master shard and replica shards in different nodes, across different zones or failure domains. This enables maintaining data persistence in case of zone failure.

- OLM Support - Redis Enterprise for Kubernetes is now RedHat OpenShift certified and can be effortlessly configured and deployed in Kubernetes clusters supporting OLM, including OpenShift 4.x clusters, with just a few clicks. OLM based deployments do not require Kubernetes cluster administrator rights to deploy the operator.

- Improve cluster nodes' pod scheduling resiliency - Redis Enterprise Cluster pod scheduling is hardened by implementing Kubernetes best practices and providing configuration recommendations to cluster operators. Scheduling resiliency minimizes the chance of cluster node pods eviction or failure to schedule.
See the top 4 articles in the new [Additonal Topics](https://github.com/RedisLabs/redis-enterprise-k8s-docs/blob/92a2eff4b8c4ccafac459138f12e5f38acde825c/docs/topics.md#additional-topics) documentation section.

- Update app.redislabs.com API version to stable - We've updated the Redis Enterprise Cluster custom resource API from [alpha to stable](https://kubernetes.io/docs/concepts/overview/kubernetes-api/#api-versioning) to reflect the current state of maturity of our implementation.

[Both versions of the API are supported](https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definition-versioning/) by Kubernetes versions that support specifying multiple API versions.

For legacy Kubernetes versions, deployment files are available in the documentation repository that utilize the alpha version of the API.

title: Information

text: - This new release deprecates the Redis Enterprise Operator support for legacy Kubernetes version 1.8.

title: Known limitations

text:
- Custom Resource Definition Changes - In order to comply with OLM best practices, a change was required to the Redis Enterprise Cluster Custom Resource Defintion (CRD) to introduce the status sub-resource.
As a result of this change, any upgrade from an older release to this release requires a change to the CRD. Once the CRD is updated, all Redis Enterprise Clusters in the same K8s cluster must be updated to the latest release in order to continue operating properly.

- Cluster Recovery -


title: Overview

text: The Redis Enterprise K8s 5.4.14-2 release is a maintenance release providing support for the latest Redis Enterprise Software release 5.4.14 and includes bug fixes as well as the following notable changes:

title: Support for K8s 1.16

text: This release now correctly handles the API deprecations, and API version changes that K8s release 1.16 introduced.

title: Support for OpenShift 4.3; improved OLM support

text: The release now supports OpenShift 4.3. A new operator version is now available in OpenShift's Operator Hub and now includes a more comprehensive base template as well as references to documentation and support.

title: Changes to the upgrade process

text: When the Operator is upgraded to a new release, it now prevents the Redis Enterprise Cluster nodes from being automatically upgraded, unless autoUpgrade is enabled or the RS image version is explicitly updated in the Redis Enterprise Cluster (REC) spec. The change was introduced to avoid situations where an Operator upgrade initiated a rolling update to the cluster nodes' StatefulSet.

title: Deprecated support for K8s versions 1.9/1.10

text: This release deprecates support for K8s version 1.9/1.10 and OpenShift 3.9. If you are currently using these releases please contact Redis support for information about migrating to a new K8s release.

title: Coming soon

text:
- The Database Custom Resource(CR), which represents Redis Enterprise databases, is in development and planned to be part of an upcoming release. The Database Controller for the Database CR is part of the Redis Enterprise K8s Operator. It is disabled in this release.
- The next release is planned to support K8s 1.17 and drop support for K8s versions 1.9/1.10.


title: Overview

text: The Redis Enterprise [K8s 6.0.12-5](https://github.com/RedisLabs/redis-enterprise-k8s-docs/releases/tag/v6.0.12-5) release is a *major release* on top of [6.0.8-20](https://github.com/RedisLabs/redis-enterprise-k8s-docs/releases/tag/v6.0.8-20) providing support for the [Redis Enterprise Software release 6.0.12-57](https://docs.redislabs.com/latest/rs/release-notes/rs-6-0-12-january-2021/) and includes several enhancements and bug fixes.

 * Database custom resources now support roles permissions (role to Redis ACL bindings). (RED49780)

title: Feature Improvements

text:
* The license information has been added to the REC status. (RED43078)
 * `kubectl get rec` now displays more information (i.e., added "NODES", "VERSION", "STATE", "SPEC STATUS"). (RED46428)
 * The `extraLabels` in the cluster spec now applies to the PV and PVC at creation. (RED48694)
 * Added [Rancher 2.5](https://rancher.com/products/rancher/2.5) support. (RED50211)
 * Added K8s (Kops) 1.19 support. (RED50211)

 * Database resources can now disable the default database user. (RED50215)
 * REC credentials no longer use environment variables in pods. (RED47969)

title: Important fixes

text:
* Fixed an issue where pods are stuck terminating during teardown. (RED44726)
 * Fixed an issue where pods are stuck terminating during cluster recovery. (RED43846)
 * Changed the operator logs to use human-readable dates and times. (RED39026)
 * Fixed the display of resources in the OLM (OpenShift). (RED48116)
 * Fixed backup configuration issue for GCS without a subdir. (RED49299)

title: Known limitations

title: CrashLoopBackOff causes cluster recovery to be incomplete  (RED33713)

text: When a pod's status is `CrashLoopBackOff` and we run the cluster recovery, the process will not complete. The workaround is to delete the crashing pods manually. The recovery process will then continue.

title: Long cluster names cause routes to be rejected  (RED25871)

text: A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name will exceed 63 characters. The workaround is to limit cluster name to 20 characters or fewer.

title: Cluster CR (REC) errors are not reported after invalid updates (RED25542)

text: A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.

title: An unreachable cluster has status running (RED32805)

text: When a cluster is in an unreachable state, the state is still `running` instead of being reported as an error.

title: Readiness probe incorrect on failures (RED39300)

text: STS Readiness probe does not mark a node as "not ready" when running `rladmin status` on the node fails.

title: Role missing on replica sets (RED39002)

text: The `redis-enterprise-operator` role is missing permission on replica sets.

title: Private registries are not supported on OpenShift 3.11 (RED38579)

text: Openshift 3.11 does not support DockerHub private registries. This is a known OpenShift issue.

title: Internal DNS and Kubernetes DNS may have conflicts (RED37462)

text: 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.

title: 5.4.10 negatively impacts 5.4.6 (RED37233)

text: Kubernetes-based 5.4.10 deployments seem to negatively impact existing 5.4.6 deployments that share a Kubernetes cluster.

title: Node CPU usage is reported instead of pod CPU usage (RED36884)

text: In Kubernetes, the node CPU usage we report on is the usage of the Kubernetes worker node hosting the REC pod.

title: Clusters must be named "rec" in OLM-based deployments (RED39825)

text: 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) is bound to a specific service account name (i.e., "rec"). The workaround is to name the cluster "rec".

title: Master pod label in Rancher (RED42896)

text: The master pod is not always labeled in Rancher.

title: REC clusters fail to start on Kubernetes clusters with unsynchronized clocks (RED47254)

text: 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.

title: Deleting an OpenShift project with an REC deployed may hang (RED47192)

text:
When a 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. As such, until the
REDB resources are deleted, the project deletion will hang. The fix is to delete the
REDB resources first and the REC second. Afterwards, you may delete the project.

title: REC extraLabels are not applied to PVCs on K8s versions 1.15 or older (RED51921)

text:
In K8s 1.15 or older, the PVC labels come from the match selectors and not the
PVC templates. As such, these versions can not support PVC labels. If this feature
is required, the only fix is to upgrade the K8s cluster to a newer version.

title: Compatibility Notes

text:
* OpenShift 4.6 and Rancher/kOps 1.19 are now supported.
 * Rancher 2.5 is now supported.
 * AKS (K8s 1.18) is now supported.

title: Deprecation notice

text:
* OpenShift 4.1, 4.2, and 4.3 are now deprecated.
 * GKE K8s version 1.14 is deprecated.
 * kOps 1.13 and 1.14 are deprecated.

title: Important fixes

text:
- The upgrade process may have failed in certain situations (i.e., with CRDB databases). We now ensure that rlutil runs at bootstrap to complete the upgrade process. (RED43635)
- The example and default custom resource for the REC in the OLM now correctly uses 'nodes' (RED43847)
- Fixes for security vulnerabilities in the server rigger image: upgraded to httpd 2.4.42, Kubernetes Python Client 8.0.1, and removed localhost private key. (RED42495)
- A fix for an internal logging issue that caused errors to incorrectly show up on the operator log when databases are created even though the creation succeeded. (RED43336)

title: Known limitations

text:

- Role missing on replica sets (RED39002) - The redis-enterprise-operator role is missing permission on replica sets.

- Private registries are not supported on OpenShift 3.11 (RED38579) - Openshift 3.11 doesn't support dockerhub private registry. This is a known OpenShift issue.

- Internal DNS and K8s DNS may have conflicts (RED37462) - DNS conflicts are possible between the cluster mdns_server and the K8s DNS. This only impacts DNS resolution from within cluster nodes for K8s DNS names.

- 5.4.10 negatively impacts 5.4.6 (RED37233) - K8S-based 5.4.10 clusters seem to negatively impact existing 5.4.6

- Node CPU usage is reported instead of pod CPU usage (RED36884) - In Kubernetes, the node CPU usage we report on is the usage of the K8S worker node hosting the REC pod.

- Clusters must be named "rec" in OLM-based deployments (RED39825) - 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) is bound to a specific service account name (i.e., "rec"). The workaround is to name the cluster "rec".

- Updating UI service in Rancher (RED45771) - Updating the UI service type may fail in Rancher. When this happens, delete the service manually and the operator will recreate it correctly.

- Master pod label in Rancher (RED42896) - Master pod is not always labeled in Rancher.

text:
* **Redis Enterprise** - redislabs/redis:6.0.6-39 or redislabs/redis:6.0.6-39.rhel7-openshift
 * **Operator** - redislabs/operator:6.0.6-24
 * **Services Rigger** - redislabs/k8s-controller:6.0.6-24 or redislabs/services-manager:6.0.6-24 (on the RedHat registry)

title: Important fixes

text:
* A fix for database observability where after 24 hours after creation or update, the controller was unable to observe the database (RED46149)
 * A fix for a log collector crash on Windows when pods were not running (RED45477)

title: Known limitations

title: CrashLoopBackOff causes cluster recovery to be incomplete  (RED33713)

text: When a pod status is CrashLoopBackOff and we run the cluster recovery, the process will not complete. The workaround is to delete the crashing pods manually and recovery process will continue.

title: Long cluster names cause routes to be rejected  (RED25871)

text: A cluster name longer than 20 characters will result in a rejected route configuration as the host part of the domain name exceeds 63 characters. The workaround is to limit cluster name to 20 characters or less.

title: Cluster CR (REC) errors are not reported after invalid updates (RED25542)

text: A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.

title: An unreachable cluster has status running (RED32805)

text: When a cluster is in an unreachable state the state is still running instead of being reported as an error.

text: STS Readiness probe doesn't mark a node as not ready when rladmin status on the node fails.

title: Role missing on replica sets (RED39002)

text: The redis-enterprise-operator role is missing permission on replica sets.

text: Openshift 3.11 doesn't support dockerhub private registry. This is a known OpenShift issue.
