Chapter 7. Troubleshooting
7.1. Verifying node health
7.1.1. Reviewing node status, resource usage, and configuration
Review cluster node health status, resource consumption statistics, and node logs. Additionally, query kubelet status on individual nodes.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. -
You have installed the OpenShift CLI (
oc).
Procedure
List the name, status, and role for all nodes in the cluster:
$ oc get nodes
Summarize CPU and memory usage for each node within the cluster:
$ oc adm top nodes
Summarize CPU and memory usage for a specific node:
$ oc adm top node my-node
7.2. Troubleshooting Operator issues
Operators are a method of packaging, deploying, and managing an OpenShift Dedicated application. They act like an extension of the software vendor’s engineering team, watching over an OpenShift Dedicated environment and using its current state to make decisions in real time. Operators are designed to handle upgrades seamlessly, react to failures automatically, and not take shortcuts, such as skipping a software backup process to save time.
OpenShift Dedicated 4 includes a default set of Operators that are required for proper functioning of the cluster. These default Operators are managed by the Cluster Version Operator (CVO).
As a cluster administrator, you can install application Operators from the OperatorHub using the OpenShift Dedicated web console or the CLI. You can then subscribe the Operator to one or more namespaces to make it available for developers on your cluster. Application Operators are managed by Operator Lifecycle Manager (OLM).
If you experience Operator issues, verify Operator subscription status. Check Operator pod health across the cluster and gather Operator logs for diagnosis.
7.2.1. Operator subscription condition types
Subscriptions can report the following condition types:
| Condition | Description |
|---|---|
|
| Some or all of the catalog sources to be used in resolution are unhealthy. |
|
| An install plan for a subscription is missing. |
|
| An install plan for a subscription is pending installation. |
|
| An install plan for a subscription has failed. |
|
| The dependency resolution for a subscription has failed. |
Default OpenShift Dedicated cluster Operators are managed by the Cluster Version Operator (CVO) and they do not have a Subscription object. Application Operators are managed by Operator Lifecycle Manager (OLM) and they have a Subscription object.

7.2.2. Viewing Operator subscription status by using the CLI
You can view Operator subscription status by using the CLI.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. -
You have installed the OpenShift CLI (
oc).
Procedure
List Operator subscriptions:
$ oc get subs -n <operator_namespace>
Use the
oc describecommand to inspect aSubscriptionresource:$ oc describe sub <subscription_name> -n <operator_namespace>
In the command output, find the
Conditionssection for the status of Operator subscription condition types. In the following example, theCatalogSourcesUnhealthycondition type has a status offalsebecause all available catalog sources are healthy:Example output
Name: cluster-logging Namespace: openshift-logging Labels: operators.coreos.com/cluster-logging.openshift-logging= Annotations: <none> API Version: operators.coreos.com/v1alpha1 Kind: Subscription # ... Conditions: Last Transition Time: 2019-07-29T13:42:57Z Message: all available catalogsources are healthy Reason: AllCatalogSourcesHealthy Status: False Type: CatalogSourcesUnhealthy # ...
Default OpenShift Dedicated cluster Operators are managed by the Cluster Version Operator (CVO) and they do not have a Subscription object. Application Operators are managed by Operator Lifecycle Manager (OLM) and they have a Subscription object.
7.2.3. Viewing Operator catalog source status by using the CLI
You can view the status of an Operator catalog source by using the CLI.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. -
You have installed the OpenShift CLI (
oc).
Procedure
List the catalog sources in a namespace. For example, you can check the
openshift-marketplacenamespace, which is used for cluster-wide catalog sources:$ oc get catalogsources -n openshift-marketplace
Example output
NAME DISPLAY TYPE PUBLISHER AGE certified-operators Certified Operators grpc Red Hat 55m community-operators Community Operators grpc Red Hat 55m example-catalog Example Catalog grpc Example Org 2m25s redhat-marketplace Red Hat Marketplace grpc Red Hat 55m redhat-operators Red Hat Operators grpc Red Hat 55m
Use the
oc describecommand to get more details and status about a catalog source:$ oc describe catalogsource example-catalog -n openshift-marketplace
Example output
Name: example-catalog Namespace: openshift-marketplace Labels: <none> Annotations: operatorframework.io/managed-by: marketplace-operator target.workload.openshift.io/management: {"effect": "PreferredDuringScheduling"} API Version: operators.coreos.com/v1alpha1 Kind: CatalogSource # ...

TRANSIENT_FAILURE. This state indicates that there is a problem establishing a connection for the catalog source.List the pods in the namespace where your catalog source was created:
$ oc get pods -n openshift-marketplace
Example output
NAME READY STATUS RESTARTS AGE certified-operators-cv9nn 1/1 Running 0 36m community-operators-6v8lp 1/1 Running 0 36m marketplace-operator-86bfc75f9b-jkgbc 1/1 Running 0 42m example-catalog-bwt8z 0/1 ImagePullBackOff 0 3m55s redhat-marketplace-57p8c 1/1 Running 0 36m redhat-operators-smxx8 1/1 Running 0 36m
When a catalog source is created in a namespace, a pod for the catalog source is created in that namespace. In the preceding example output, the status for the
example-catalog-bwt8zpod isImagePullBackOff. This status indicates that there is an issue pulling the catalog source’s index image.Use the
oc describecommand to inspect a pod for more detailed information:$ oc describe pod example-catalog-bwt8z -n openshift-marketplace
Example output

7.2.4. Querying Operator pod status
You can list Operator pods within a cluster and their status. You can also collect a detailed Operator pod summary.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. - Your API service is still functional.
-
You have installed the OpenShift CLI (
oc).
Procedure
List Operators running in the cluster. The output includes Operator version, availability, and up-time information:
$ oc get clusteroperators
List Operator pods running in the Operator’s namespace, plus pod status, restarts, and age:
$ oc get pod -n <operator_namespace>
Output a detailed Operator pod summary:
$ oc describe pod <operator_pod_name> -n <operator_namespace>
7.2.5. Gathering Operator logs
If you experience Operator issues, you can gather detailed diagnostic information from Operator pod logs.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. - Your API service is still functional.
-
You have installed the OpenShift CLI (
oc). - You have the fully qualified domain names of the control plane or control plane machines.
Procedure
List the Operator pods that are running in the Operator’s namespace, plus the pod status, restarts, and age:
$ oc get pods -n <operator_namespace>
Review logs for an Operator pod:
$ oc logs pod/<pod_name> -n <operator_namespace>
If an Operator pod has multiple containers, the preceding command will produce an error that includes the name of each container. Query logs from an individual container:
$ oc logs pod/<operator_pod_name> -c <container_name> -n <operator_namespace>
If the API is not functional, review Operator pod and container logs on each control plane node by using SSH instead. Replace
<master-node>.<cluster_name>.<base_domain>with appropriate values.List pods on each control plane node:
$ ssh core@<master-node>.<cluster_name>.<base_domain> sudo crictl pods
For any Operator pods not showing a
Readystatus, inspect the pod’s status in detail. Replace<operator_pod_id>with the Operator pod’s ID listed in the output of the preceding command:$ ssh core@<master-node>.<cluster_name>.<base_domain> sudo crictl inspectp <operator_pod_id>
List containers related to an Operator pod:
$ ssh core@<master-node>.<cluster_name>.<base_domain> sudo crictl ps --pod=<operator_pod_id>
For any Operator container not showing a
Readystatus, inspect the container’s status in detail. Replace<container_id>with a container ID listed in the output of the preceding command:$ ssh core@<master-node>.<cluster_name>.<base_domain> sudo crictl inspect <container_id>
Review the logs for any Operator containers not showing a
Readystatus. Replace<container_id>with a container ID listed in the output of the preceding command:$ ssh core@<master-node>.<cluster_name>.<base_domain> sudo crictl logs -f <container_id>
NoteOpenShift Dedicated 4 cluster nodes running Red Hat Enterprise Linux CoreOS (RHCOS) are immutable and rely on Operators to apply cluster changes. Accessing cluster nodes by using SSH is not recommended. Before attempting to collect diagnostic data over SSH, review whether the data collected by running
oc adm must gatherand otheroccommands is sufficient instead. However, if the OpenShift Dedicated API is not available, or the kubelet is not properly functioning on the target node,ocoperations will be impacted. In such situations, it is possible to access nodes usingssh core@<node>.<cluster_name>.<base_domain>.
7.3. Investigating pod issues
OpenShift Dedicated leverages the Kubernetes concept of a pod, which is one or more containers deployed together on one host. A pod is the smallest compute unit that can be defined, deployed, and managed on OpenShift Dedicated 4.
After a pod is defined, it is assigned to run on a node until its containers exit, or until it is removed. Depending on policy and exit code, Pods are either removed after exiting or retained so that their logs can be accessed.
The first thing to check when pod issues arise is the pod’s status. If an explicit pod failure has occurred, observe the pod’s error state to identify specific image, container, or pod network issues. Focus diagnostic data collection according to the error state. Review pod event messages, as well as pod and container log information. Diagnose issues dynamically by accessing running Pods on the command line, or start a debug pod with root access based on a problematic pod’s deployment configuration.
7.3.1. Understanding pod error states
Pod failures return explicit error states that can be observed in the status field in the output of oc get pods. Pod error states cover image, container, and container network related failures.
The following table provides a list of pod error states along with their descriptions.
| Pod error state | Description |
|---|---|
|
| Generic image retrieval error. |
|
| Image retrieval failed and is backed off. |
|
| The specified image name was invalid. |
|
| Image inspection did not succeed. |
|
|
|
|
| When attempting to retrieve an image from a registry, an HTTP error was encountered. |
|
| The specified container is either not present or not managed by the kubelet, within the declared pod. |
|
| Container initialization failed. |
|
| None of the pod’s containers started successfully. |
|
| None of the pod’s containers were killed successfully. |
|
| A container has terminated. The kubelet will not attempt to restart it. |
|
| A container or image attempted to run with root privileges. |
|
| Pod sandbox creation did not succeed. |
|
| Pod sandbox configuration was not obtained. |
|
| A pod sandbox did not stop successfully. |
|
| Network initialization failed. |
|
| Network termination failed. |
7.3.2. Reviewing pod status
You can query pod status and error states. You can also query a pod’s associated deployment configuration and review base image availability.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. -
You have installed the OpenShift CLI (
oc). -
skopeois installed.
Procedure
Switch into a project:
$ oc project <project_name>
List pods running within the namespace, as well as pod status, error states, restarts, and age:
$ oc get pods
Determine whether the namespace is managed by a deployment configuration:
$ oc status
If the namespace is managed by a deployment configuration, the output includes the deployment configuration name and a base image reference.
Inspect the base image referenced in the preceding command’s output:
$ skopeo inspect docker://<image_reference>
If the base image reference is not correct, update the reference in the deployment configuration:
$ oc edit deployment/my-deployment
When deployment configuration changes on exit, the configuration will automatically redeploy. Watch pod status as the deployment progresses, to determine whether the issue has been resolved:
$ oc get pods -w
Review events within the namespace for diagnostic information relating to pod failures:
$ oc get events
7.3.3. Inspecting pod and container logs
You can inspect pod and container logs for warnings and error messages related to explicit pod failures. Depending on policy and exit code, pod and container logs remain available after pods have been terminated.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. - Your API service is still functional.
-
You have installed the OpenShift CLI (
oc).
Procedure
Query logs for a specific pod:
$ oc logs <pod_name>
Query logs for a specific container within a pod:
$ oc logs <pod_name> -c <container_name>
Logs retrieved using the preceding
oc logscommands are composed of messages sent to stdout within pods or containers.Inspect logs contained in
/var/log/within a pod.List log files and subdirectories contained in
/var/logwithin a pod:$ oc exec <pod_name> -- ls -alh /var/log
Example output

Query a specific log file contained in
/var/logwithin a specific container:$ oc exec <pod_name> -c <container_name> cat /var/log/<path_to_log>
7.3.4. Accessing running pods
You can review running pods dynamically by opening a shell inside a pod or by gaining network access through port forwarding.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. - Your API service is still functional.
-
You have installed the OpenShift CLI (
oc).
Procedure
Switch into the project that contains the pod you would like to access. This is necessary because the
oc rshcommand does not accept the-nnamespace option:$ oc project <namespace>
Start a remote shell into a pod:
$ oc rsh <pod_name> 1- 1
- If a pod has multiple containers,
oc rshdefaults to the first container unless-c <container_name>is specified.
Start a remote shell into a specific container within a pod:
$ oc rsh -c <container_name> pod/<pod_name>
Create a port forwarding session to a port on a pod:
$ oc port-forward <pod_name> <host_port>:<pod_port> 1- 1
- Enter
Ctrl+Cto cancel the port forwarding session.
7.3.5. Starting debug pods with root access
You can start a debug pod with root access, based on a problematic pod’s deployment or deployment configuration. Pod users typically run with non-root privileges, but running troubleshooting pods with temporary root privileges can be useful during issue investigation.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. - Your API service is still functional.
-
You have installed the OpenShift CLI (
oc).
Procedure
Start a debug pod with root access, based on a deployment.
Obtain a project’s deployment name:
$ oc get deployment -n <project_name>
Start a debug pod with root privileges, based on the deployment:
$ oc debug deployment/my-deployment --as-root -n <project_name>
Start a debug pod with root access, based on a deployment configuration.
Obtain a project’s deployment configuration name:
$ oc get deploymentconfigs -n <project_name>
Start a debug pod with root privileges, based on the deployment configuration:
$ oc debug deploymentconfig/my-deployment-configuration --as-root -n <project_name>
You can append -- <command> to the preceding oc debug commands to run individual commands within a debug pod, instead of running an interactive shell.
7.3.6. Copying files to and from pods and containers
You can copy files to and from a pod to test configuration changes or gather diagnostic information.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. - Your API service is still functional.
-
You have installed the OpenShift CLI (
oc).
Procedure
Copy a file to a pod:
$ oc cp <local_path> <pod_name>:/<path> -c <container_name> 1- 1
- The first container in a pod is selected if the
-coption is not specified.
Copy a file from a pod:
$ oc cp <pod_name>:/<path> -c <container_name> <local_path> 1- 1
- The first container in a pod is selected if the
-coption is not specified.
NoteFor
oc cpto function, thetarbinary must be available within the container.
7.4. Troubleshooting storage issues
7.4.1. Resolving multi-attach errors
When a node crashes or shuts down abruptly, the attached ReadWriteOnce (RWO) volume is expected to be unmounted from the node so that it can be used by a pod scheduled on another node.
However, mounting on a new node is not possible because the failed node is unable to unmount the attached volume.
A multi-attach error is reported:
Example output
Unable to attach or mount volumes: unmounted volumes=[sso-mysql-pvol], unattached volumes=[sso-mysql-pvol default-token-x4rzc]: timed out waiting for the condition Multi-Attach error for volume "pvc-8837384d-69d7-40b2-b2e6-5df86943eef9" Volume is already used by pod(s) sso-mysql-1-ns6b4
Procedure
To resolve the multi-attach issue, use one of the following solutions:
Enable multiple attachments by using RWX volumes.
For most storage solutions, you can use ReadWriteMany (RWX) volumes to prevent multi-attach errors.
Recover or delete the failed node when using an RWO volume.
For storage that does not support RWX, such as VMware vSphere, RWO volumes must be used instead. However, RWO volumes cannot be mounted on multiple nodes.
If you encounter a multi-attach error message with an RWO volume, force delete the pod on a shutdown or crashed node to avoid data loss in critical workloads, such as when dynamic persistent volumes are attached.
$ oc delete pod <old_pod> --force=true --grace-period=0
This command deletes the volumes stuck on shutdown or crashed nodes after six minutes.
7.5. Investigating monitoring issues
OpenShift Dedicated includes a preconfigured, preinstalled, and self-updating monitoring stack that provides monitoring for core platform components. In OpenShift Dedicated 4, cluster administrators can optionally enable monitoring for user-defined projects.
Use these procedures if the following issues occur:
- Your own metrics are unavailable.
- Prometheus is consuming a lot of disk space.
-
The
KubePersistentVolumeFillingUpalert is firing for Prometheus.
7.5.2. Determining why Prometheus is consuming a lot of disk space
Developers can create labels to define attributes for metrics in the form of key-value pairs. The number of potential key-value pairs corresponds to the number of possible values for an attribute. An attribute that has an unlimited number of potential values is called an unbound attribute. For example, a customer_id attribute is unbound because it has an infinite number of possible values.
Every assigned key-value pair has a unique time series. The use of many unbound attributes in labels can result in an exponential increase in the number of time series created. This can impact Prometheus performance and can consume a lot of disk space.
You can use the following measures when Prometheus consumes a lot of disk:
- Check the time series database (TSDB) status using the Prometheus HTTP API for more information about which labels are creating the most time series data. Doing so requires cluster administrator privileges.
- Check the number of scrape samples that are being collected.
Reduce the number of unique time series that are created by reducing the number of unbound attributes that are assigned to user-defined metrics.
NoteUsing attributes that are bound to a limited set of possible values reduces the number of potential key-value pair combinations.
- Enforce limits on the number of samples that can be scraped across user-defined projects. This requires cluster administrator privileges.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. -
You have installed the OpenShift CLI (
oc).
Procedure
-
In the Administrator perspective, navigate to Observe
Metrics. Enter a Prometheus Query Language (PromQL) query in the Expression field. The following example queries help to identify high cardinality metrics that might result in high disk space consumption:
By running the following query, you can identify the ten jobs that have the highest number of scrape samples:
topk(10, max by(namespace, job) (topk by(namespace, job) (1, scrape_samples_post_metric_relabeling)))
By running the following query, you can pinpoint time series churn by identifying the ten jobs that have created the most time series data in the last hour:
topk(10, sum by(namespace, job) (sum_over_time(scrape_series_added[1h])))
Investigate the number of unbound label values assigned to metrics with higher than expected scrape sample counts:
- If the metrics relate to a user-defined project, review the metrics key-value pairs assigned to your workload. These are implemented through Prometheus client libraries at the application level. Try to limit the number of unbound attributes referenced in your labels.
- If the metrics relate to a core OpenShift Dedicated project, create a Red Hat support case on the Red Hat Customer Portal.
Review the TSDB status using the Prometheus HTTP API by following these steps when logged in as a
dedicated-admin:Get the Prometheus API route URL by running the following command:
$ HOST=$(oc -n openshift-monitoring get route prometheus-k8s -ojsonpath={.status.ingress[].host})Extract an authentication token by running the following command:
$ TOKEN=$(oc whoami -t)
Query the TSDB status for Prometheus by running the following command:
$ curl -H "Authorization: Bearer $TOKEN" -k "https://$HOST/api/v1/status/tsdb"
Example output
"status": "success","data":{"headStats":{"numSeries":507473, "numLabelPairs":19832,"chunkCount":946298,"minTime":1712253600010, "maxTime":1712257935346},"seriesCountByMetricName": [{"name":"etcd_request_duration_seconds_bucket","value":51840}, {"name":"apiserver_request_sli_duration_seconds_bucket","value":47718}, ...

7.5.3. Resolving the KubePersistentVolumeFillingUp alert firing for Prometheus
As a cluster administrator, you can resolve the KubePersistentVolumeFillingUp alert being triggered for Prometheus.
The critical alert fires when a persistent volume (PV) claimed by a prometheus-k8s-* pod in the openshift-monitoring project has less than 3% total space remaining. This can cause Prometheus to function abnormally.
There are two KubePersistentVolumeFillingUp alerts:
-
Critical alert: The alert with the
severity="critical"label is triggered when the mounted PV has less than 3% total space remaining. -
Warning alert: The alert with the
severity="warning"label is triggered when the mounted PV has less than 15% total space remaining and is expected to fill up within four days.
To address this issue, you can remove Prometheus time-series database (TSDB) blocks to create more space for the PV.
Prerequisites
-
You have access to the cluster as a user with the
dedicated-adminrole. -
You have installed the OpenShift CLI (
oc).
Procedure
List the size of all TSDB blocks, sorted from oldest to newest, by running the following command:
$ oc debug <prometheus_k8s_pod_name> -n openshift-monitoring \1 -c prometheus --image=$(oc get po -n openshift-monitoring <prometheus_k8s_pod_name> \2 -o jsonpath='{.spec.containers[?(@.name=="prometheus")].image}') \ -- sh -c 'cd /prometheus/;du -hs $(ls -dt */ | grep -Eo "[0-9|A-Z]{26}")'
Example output
308M 01HVKMPKQWZYWS8WVDAYQHNMW6 52M 01HVK64DTDA81799TBR9QDECEZ 102M 01HVK64DS7TRZRWF2756KHST5X 140M 01HVJS59K11FBVAPVY57K88Z11 90M 01HVH2A5Z58SKT810EM6B9AT50 152M 01HV8ZDVQMX41MKCN84S32RRZ1 354M 01HV6Q2N26BK63G4RYTST71FBF 156M 01HV664H9J9Z1FTZD73RD1563E 216M 01HTHXB60A7F239HN7S2TENPNS 104M 01HTHMGRXGS0WXA3WATRXHR36B
Identify which and how many blocks could be removed, then remove the blocks. The following example command removes the three oldest Prometheus TSDB blocks from the
prometheus-k8s-0pod:$ oc debug prometheus-k8s-0 -n openshift-monitoring \ -c prometheus --image=$(oc get po -n openshift-monitoring prometheus-k8s-0 \ -o jsonpath='{.spec.containers[?(@.name=="prometheus")].image}') \ -- sh -c 'ls -latr /prometheus/ | egrep -o "[0-9|A-Z]{26}" | head -3 | \ while read BLOCK; do rm -r /prometheus/$BLOCK; done'Verify the usage of the mounted PV and ensure there is enough space available by running the following command:
$ oc debug <prometheus_k8s_pod_name> -n openshift-monitoring \1 --image=$(oc get po -n openshift-monitoring <prometheus_k8s_pod_name> \2 -o jsonpath='{.spec.containers[?(@.name=="prometheus")].image}') -- df -h /prometheus/
The following example output shows the mounted PV claimed by the
prometheus-k8s-0pod that has 63% of space remaining:Example output
Starting pod/prometheus-k8s-0-debug-j82w4 ... Filesystem Size Used Avail Use% Mounted on /dev/nvme0n1p4 40G 15G 40G 37% /prometheus Removing debug pod ...
7.6. Diagnosing OpenShift CLI (oc) issues
7.6.1. Understanding OpenShift CLI (oc) log levels
With the OpenShift CLI (oc), you can create applications and manage OpenShift Dedicated projects from a terminal.
If oc command-specific issues arise, increase the oc log level to output API request, API response, and curl request details generated by the command. This provides a granular view of a particular oc command’s underlying operation, which in turn might provide insight into the nature of a failure.
oc log levels range from 1 to 10. The following table provides a list of oc log levels, along with their descriptions.

7.6.2. Specifying OpenShift CLI (oc) log levels
You can investigate OpenShift CLI (oc) issues by increasing the command’s log level.
The OpenShift Dedicated user’s current session token is typically included in logged curl requests where required. You can also obtain the current user’s session token manually, for use when testing aspects of an oc command’s underlying process step-by-step.
Prerequisites
-
Install the OpenShift CLI (
oc).
Procedure
Specify the
oclog level when running anoccommand:$ oc <command> --loglevel <log_level>
where:
- <command>
- Specifies the command you are running.
- <log_level>
- Specifies the log level to apply to the command.
To obtain the current user’s session token, run the following command:
$ oc whoami -t
Example output
sha256~RCV3Qcn7H-OEfqCGVI0CvnZ6...
7.7. Red Hat managed resources
7.7.1. Overview
The following covers all OpenShift Dedicated resources that are managed or protected by the Service Reliability Engineering Platform (SRE-P) Team. Customers should not attempt to modify these resources because doing so can lead to cluster instability.
7.7.2. Hive managed resources
The following list displays the OpenShift Dedicated resources managed by OpenShift Hive, the centralized fleet configuration management system. These resources are in addition to the OpenShift Container Platform resources created during installation. OpenShift Hive continually attempts to maintain consistency across all OpenShift Dedicated clusters. Changes to OpenShift Dedicated resources should be made through OpenShift Cluster Manager so that OpenShift Cluster Manager and Hive are synchronized. Contact ocm-feedback@redhat.com if OpenShift Cluster Manager does not support modifying the resources in question.

OpenShift Dedicated add-ons are services available for installation after cluster installation. These additional services include Red Hat OpenShift Dev Spaces, Red Hat OpenShift API Management, and Cluster Logging Operator. Any changes to resources within the following namespaces can be overridden by the add-on during upgrades, which can lead to unsupported configurations for the add-on functionality.

7.7.5. OpenShift Dedicated validating webhooks
OpenShift Dedicated validating webhooks are a set of dynamic admission controls maintained by the OpenShift SRE team. These HTTP callbacks, also known as webhooks, are called for various types of requests to ensure cluster stability. The following list describes the various webhooks with rules containing the registered operations and resources that are controlled. Any attempt to circumvent these validating webhooks could affect the stability and supportability of the cluster.
