Why can't I access the Red Hat OpenShift web console? 

  What’s happening 

When you try to access your Satellite cluster through the Red Hat OpenShift console, you see an error message similar to the following:

2021-07-23T14:15:33Z auth: error contacting auth provider (retrying in 10s): request to OAuth issuer endpoint https://...us-east.satellite.appdomain.cloud:0000/oauth/token failed: Head https://...us-east.satellite.appdomain.cloud:0000: x509: certificate has expired or is not yet valid.

  Why it’s happening 

An expired or invalidated security ticket is preventing you from accessing the Red Hat OpenShift console.

  How to fix it 

Follow the steps to validate your certificate.



1.  [Access your Satellite cluster](https://cloud.ibm.com/docs/openshift?topic=openshift-access_clusteraccess_cluster_sat).
2.  Run the [master refresh](https://cloud.ibm.com/docs/openshift?topic=openshift-kubernetes-service-clics_apiserver_refresh) command.

ibmcloud oc cluster master refresh --cluster <cluster_id>
3.  Wait a few minutes and try to access the console again.
After logging in to my cluster, why do I see a no resources found message? 

Virtual Private Cloud

Classic infrastructure

  What’s happening 

When you are running an oc command such as oc get nodes or oc get secrets, you see an error message similar to the following.

No resources found.

  Why it’s happening 

Your Red Hat OpenShift token is expired. Red Hat OpenShift token that are generated by using your IBM Cloud IAM credentials expire in 24 hours.

  How to fix it 

Re-authenticate with the Red Hat OpenShift token by [copying the oc login command from the web console](https://cloud.ibm.com/docs/openshift?topic=openshift-access_clusteraccess_public_se) or [creating an API key](https://cloud.ibm.com/docs/openshift?topic=openshift-access_clusteraccess_api_key).
* If you are using a vSAN datastore, delete any persistent volumes that you no longer need before you uninstall Red Hat OpenShift. Any volumes that are not deleted will remain in the vSAN storage after the Red Hat OpenShift uninstallation.
* Before you delete the service, you must remove any personal VMs that were deployed with this service, from the storage. Red Hat OpenShift only orders personal VMs if it’s not vSAN.

Why do I see wrong s3fs or IAM API endpoints when I create a PVC? 

Virtual Private Cloud

Classic infrastructure

This troubleshooting topic applies only to Red Hat OpenShift clusters that run version 3.11.

 What’s happening 

When you create the PVC, the PVC remains in a pending state. After you run the oc describe pvc <pvc_name> command, you see one of the following error messages:

Bad value for ibm.io/object-store-endpoint XXXX: scheme is missing. Must be of the form http://<hostname> or https://<hostname>

Bad value for ibm.io/iam-endpoint XXXX: scheme is missing. Must be of the form http://<hostname> or https://<hostname>

 Why it’s happening 

The s3fs API endpoint for the bucket that you want to use might have the wrong format, or your cluster is deployed in a location that is supported in Red Hat OpenShift on IBM Cloud but is not yet supported by the IBM Cloud Object Storage plug-in.

 How to fix it 

Complete the following steps:



1. Check the s3fs API endpoint that was automatically assigned by the ibmc Helm plug-in to your storage classes during the IBM Cloud Object Storage plug-in installation. The endpoint is based on the location that your cluster is deployed to.

oc get sc ibmc-s3fs-standard-regional -o yaml | grep object-store-endpoint

If the command returns ibm.io/object-store-endpoint: NA, your cluster is deployed in a location that is supported in Red Hat OpenShift on IBM Cloud but is not yet supported by the IBM Cloud Object Storage plug-in. To add the location to the Red Hat OpenShift on IBM Cloud, post a question in our public Slack or open an IBM Cloud support case.

Red Hat OpenShift charges
: Now when you create Red Hat OpenShift clusters, you are not charged for the Red Hat Enterprise Linux operating system that is installed on the worker nodes. For more information, see [What am I charged for when I use Red Hat OpenShift clusters?](https://cloud.ibm.com/docs/openshift?topic=openshift-faqscharges).

 26 November 2019 

CLI change log
: Updated the IBM Cloud Kubernetes Service CLI plug-in change log page for the [release of version 0.4.61](https://cloud.ibm.com/docs/openshift?topic=openshift-cs_cli_changelog).

Diagnostics and Debug Tool add-on for Red Hat OpenShift clusters
If you change the SCC that a system group is assigned to, default components that belong to the system group might experience errors due to the change in permissions.

Are any SCCs set by default?
: By default, Red Hat OpenShift on IBM Cloud clusters include a standard set of [Red Hat OpenShift SCCs](https://cloud.ibm.com/docs/openshift?topic=openshift-openshift_sccoc_sccs). Additionally, clusters have [IBM SCCs](https://cloud.ibm.com/docs/openshift?topic=openshift-openshift_sccibm_sccs) that closely resemble the [Kubernetes pod security policies of community Kubernetes clusters in IBM Cloud Kubernetes Service](https://cloud.ibm.com/docs/containers?topic=containers-pspibm_psp). These IBM SCCs are included for improved portability with IBM Cloud Private packages such as Cloud Paks.

What SCCs are applied to my resources by default?
: If you don't specify a security context, the Red Hat OpenShift restricted (or restricted-v2 in 4.11 and later) security context constraint is applied by default. To check a pod's security context, describe the pod and look for the SCC annotation, such as in the following example.

oc describe pod <pod_name>

Name: <pod_name>
Namespace: <project_name>
...
Annotations: openshift.io/...
openshift.io/scc=restricted
...

Can I use Kubernetes pod security policies instead?
: No. [Kubernetes pod security policies](https://kubernetes.io/docs/concepts/security/pod-security-policy/) (PSPs) are originally based on Red Hat OpenShift SCCs. However, Red Hat OpenShift supports only SCCs, not PSPs.

The default Red Hat OpenShift SCCs are stricter than the default PSPs in community Kubernetes clusters.
Private VLAN routers always begin with bcr (back-end router) and public VLAN routers always begin with fcr (front-end router). When you create a cluster and specify the public and private VLANs, the number and letter combination after those prefixes must match.

--name <name>
: Specify a name for your cluster. The name must start with a letter, can contain letters, numbers, periods (.), and hyphen (-), and must be 35 characters or fewer. Use a name that is unique across regions. The cluster name and the region in which the cluster is deployed form the fully qualified domain name for the Ingress subdomain. To ensure that the Ingress subdomain is unique within a region, the cluster name might be truncated and appended with a random value within the Ingress domain name.

--workers <number>
: Specify at least 2 worker nodes to include in the cluster. For more information, see [What is the smallest size cluster that I can make?](https://cloud.ibm.com/docs/openshift?topic=openshift-faqssmallest_cluster).

--version <major.minor.patch>
: The Red Hat OpenShift version for the cluster master node. This value is required. When the version is not specified, the cluster is created with the default supported Kubernetes version. If you don't specify a supported Red Hat OpenShift version, your cluster is created as a community Kubernetes cluster. To see available versions, run ibmcloud oc versions.

--public-service-endpoint
: Enable the public cloud service endpoint so that your Red Hat OpenShift master can be accessed over the public network, for example to run oc commands from your CLI, and so that your Red Hat OpenShift master and the worker nodes can communicate over the public VLAN. You must enable the public cloud service endpoint, and can't later disable it.After you create the cluster, you can get the endpoint by running ibmcloud oc cluster get --cluster <cluster_name_or_ID>.
Why does pushing to the internal registry time out? 

Virtual Private Cloud

Classic infrastructure

  What’s happening 

You try to push an image to the [internal registry](https://cloud.ibm.com/docs/openshift?topic=openshift-registryopenshift_internal_registry), but sporadically you see an error message similar to the following.

received unexpected HTTP status: 504 Gateway Time-out

  Why it’s happening 

The default file storage device that provides the storage for the internal registry's images is initially set up with 2 IOPS and 20 GB of storage. When you push larger images, the device might time out because its IOPS is too low to support the image.

  How to fix it 

[Change the size and IOPS of the existing file storage device](https://cloud.ibm.com/docs/openshift?topic=openshift-file_storagefile_change_storage_configuration).

When you resize the volume in your IBM Cloud infrastructure account, the attached PVC description is not updated. Instead, you can log in to the openshift-image-registry (Red Hat OpenShift 4) or docker-registry (Red Hat OpenShift 3.11) pod that uses the registry-backing PVC to verify that the volume is resized.
Debugging clusters 

First check whether your issue is listed in the troubleshooting topics in the Satellite documentation. If the issue is not listed in the Satellite documentation, see the [Red Hat OpenShift on IBM Cloud troubleshooting documentation](https://cloud.ibm.com/docs/openshift?topic=openshift-debug_clusters).

For example, if you cannot access the Red Hat OpenShift console for a Red Hat OpenShift cluster on Satellite, first check whether the issue is [specific to your Satellite location setup](https://cloud.ibm.com/docs/satellite?topic=satellite-ts-console-fail). If your Satellite location setup is not the source of the issue, then check the [Red Hat OpenShift on IBM Cloud documentation for troubleshooting console issues](https://cloud.ibm.com/docs/openshift?topic=openshift-ocp-debug).
Enter the ID or name of the location where the Satellite control plane or Red Hat OpenShift cluster exists to which you want to assign the compute host. To retrieve the location ID or name, run ibmcloud sat location ls.

--cluster CLUSTER
: Required. Enter the ID or name of the cluster where you want to assign your compute host. If you want to assign your compute host to the Satellite control plane, use the location ID or name. To assign the compute host to a Red Hat OpenShift cluster, use the ID or name of the cluster. To retrieve the cluster ID or name, run ibmcloud sat cluster ls.

--host HOST
: Required. Enter the ID of the host that you want to assign to the Satellite control plane or Red Hat OpenShift cluster. To retrieve the host ID, run ibmcloud sat host ls --location <location_ID_or_name>.

--zone ZONE
: Required. The name of the zone where you want to assign the compute host. To see the zone names for your location, run ibmcloud sat location get --location <location_name_or_ID> and look for the Host Zones field.

--worker-pool WORKER_POOL
: Optional. Enter the name or ID of the worker pool in your Red Hat OpenShift cluster to which you want to add your compute host. If you want to assign hosts to your Satellite control plane, this option is not required. When you assign hosts to a Red Hat OpenShift cluster, you can include this option to specify the worker pool. If no worker pool is specified, the host is assigned to the default worker pool of the cluster.

--host-label LABEL, -hl LABEL
: Optional. Enter any labels as a key-value pair that you want to use to identify the host that you want to assign to your Satellite control plane or Red Hat OpenShift cluster. The first host that has this label and is in an unassigned state it automatically assigned to the control plane or cluster.
Why do pods remain in pending state? 

Virtual Private Cloud

Classic infrastructure

 What’s happening 

When you run oc get pods, you can see pods that remain in a Pending state.

 Why it’s happening 

If you just created the Red Hat OpenShift cluster, the worker nodes might still be configuring.

If this cluster is an existing one:



* You might not have enough capacity in your cluster to deploy the pod.
* The pod might have exceeded a resource request or limit.



 How to fix it 

This task requires the IBM Cloud IAM [Administrator platform access role](https://cloud.ibm.com/docs/openshift?topic=openshift-userschecking-perms) for the cluster and the [Manager service access role](https://cloud.ibm.com/docs/openshift?topic=openshift-userschecking-perms) for all namespaces.

If you just created the Red Hat OpenShift cluster, run the following command and wait for the worker nodes to initialize.

oc get nodes

If this cluster is an existing one, check your cluster capacity.



1. From the [Red Hat OpenShift clusters console](https://cloud.ibm.com/kubernetes/clusters?platformType=openshift), select your cluster.
2. Click Red Hat OpenShift web console.
3. Check if you have enough capacity in your cluster to deploy your pod.
4. If you don't have enough capacity in your cluster, resize your worker pool to add more nodes.



1. Review the current sizes and flavors of your worker pools to decide which one to resize.

ibmcloud oc worker-pool ls
2. Resize your worker pools to add more nodes to each zone that the pool spans.

ibmcloud oc worker-pool resize --worker-pool <worker_pool> --cluster <cluster_name_or_ID> --size-per-zone <workers_per_zone>



5. Optional: Check your pod resource requests.



1.
: Required: The level of hardware isolation for your worker node. Use dedicated if you want to have available physical resources that are dedicated to you only, or shared to allow physical resources to be shared with other IBM customers. The default is shared. For bare metal flavors, specify dedicated.

--disable-disk-encrypt
: Specifies that the disk is not encrypted. The default value is false.

-l, --label KEY1=VALUE1
: Optional: Apply key-value labels to each worker node in the worker pool. To specify multiple labels, use multiple options, such as -l key1=value1 -l key2=value2.

--operating-system SYSTEM
: Optional. The operating system of the worker nodes you want to provision in your cluster. For a list of available operating systems by cluster version, see [Red Hat OpenShift on IBM Cloud version information](https://cloud.ibm.com/docs/openshift?topic=openshift-openshift_versions).

--entitlement cloud_pak
: Include this option only if you use this cluster with an [IBM Cloud Pak](https://cloud.ibm.com/docs/openshift?topic=openshift-openshift_cloud_paks) that has a Red Hat OpenShift entitlement. When you specify the number of workers (--size-per-zone) and flavor (--flavor), make sure to specify only the number and size of worker nodes that you are entitled to use in [IBM Passport Advantage](https://www.ibm.com/software/passportadvantage/index.html). After creation, your worker pool does not charge you the Red Hat OpenShift license fee for your entitled worker nodes. Do not exceed your entitlement. Keep in mind that your OpenShift Container Platform entitlements can be used with other cloud providers or in other environments. To avoid billing issues later, make sure that you use only what you are entitled to use.
3. Red Hat OpenShift Service Mesh .





This installs the Operators in the default openshift-operators project and makes the Operators available to all projects in the cluster.





 Deploying the Red Hat OpenShift Service Mesh control plane 

The Red Hat OpenShift Service Mesh operator uses a ServiceMeshControlPlane resource to determine how to install Istio and what components you want. Let's create that resource now.



1. Create a new project by going to Home on the left pane of the web console, click Projects and then Create Project.
2. Enter istio-system in the Name and click Create.
3. Navigate to Operators and click Installed Operators.
4. Select istio-system from the Project menu on the top bar.
5. Click on Red Hat OpenShift Service Mesh. If you don't see it, wait a couple of minutes and refresh.
6. On the Details tab, under Istio Service Mesh Control Plane tile, click Create Instance or Create ServiceMeshControlPlane.
7. Then, click Create. The Operator creates Pods, services, and Service Mesh control plane components based on your configuration parameters.
8. To make sure that the Service Mesh Control Plane is installed properly, click on basic under Name in the list. On the subsequent page, you should see Components ready. Moreover, when you scroll to the Conditions section of the page, you should see the reason ComponentsReady and a message All component deployments are Available.







 Create a ServiceMeshMemberRoll 

ServiceMeshMemberRoll resource is used to to specify the namespaces associated with the Service Mesh.



1. Navigate to Operators → Installed Operators again.
2. Click on Red Hat OpenShift Service Mesh.
3. On the Details tab, under Istio Service Mesh Member Roll tile, click Create Instance or Create ServiceMeshMemberRoll and then select YAML View
4. Change your-project to bookinfo and delete the last line(- another-of-your-projects). After the edits, the YAML should look something like this:

 Installing Red Hat Ansible Tower 



1. Log in to OpenShift as an administrator from your Linux system.
* Red Hat OpenShift on IBM Cloud CBR rules that apply to all API types or the cluster API types must not reference network zones that contain IPv6 addresses. The APIs included in the cluster type don't support IPv6.
* If you add Red Hat OpenShift on IBM Cloud resources to private-only network zones, the APIs for getting and listing clusters are still accessible over the public network.
* Red Hat OpenShift on IBM Cloud CBR rules that apply to all API types or the cluster API types must not reference other services like IBM Cloud Object Storage or Key Protect
* Red Hat OpenShift on IBM Cloud CBR rules that apply to all API types or the cluster API type do not support Report-only enforcement for the cluster API type.
* Red Hat OpenShift on IBM Cloud CBR rules that apply to all API types or the cluster API types are limited to no more than 20 IPs/subnets for private rules, and 200 IPs/subnets for public rules. These limits are expected to increase after the backend scalability of our implementation of Red Hat OpenShift on IBM Cloud CBR is updated.
* Red Hat OpenShift on IBM Cloud public CBR rules that apply to the cluster API type do not effect clusters that are private service endpoint only. All public traffic to the cluster APIserver is blocked. To use public CBR rules to control access to your cluster, update your cluster to enable public service endpoint.
* Due to a limitation with how Red Hat OpenShift on IBM Cloud fetches cluster details, the APIs for getting clusters and listing clusters are still accessible regardless of the CBR rules. This means clusters are still visible (read-only) in the console and CLI. When this limitation is addressed, you must add new rules to protect the APIs for getting clusters and listing clusters.
* For Red Hat OpenShift on IBM Cloud clusters on VPC with a Public Service Endpoint, if you add public CBR rules to your cluster, make sure to also add the public gateway IP addresses of your VPC subnets to your CBR rules.
