Troubleshooting Kubernetes environments

Troubleshooting Kubernetes environments

The following topics contain information that can help you troubleshoot problems when you encounter unexpected behavior installing and using Zowe™ containers in a Kubernetes environment.

ISSUE: Deployment and ReplicaSet failed to create pod


If you are using OpenShift and see these error messages in ReplicaSet Events:

Generated from replicaset-controller
Error creating: pods "api-catalog-??????????-" is forbidden: unable to validate against any security context constraint: []

That means the Zowe ServiceAccount zowe-sa doesn't have any SecurityContextConstraint attached.


You can run this command to grant a certain level of permission, for example, privileged, to zowe-sa ServiceAccount:

oc admin policy add-scc-to-user privileged -z zowe-sa -n zowe

ISSUE: Failed to create services


If you are using OpenShift and apply services, you may see this error:

The Service "api-catalog-service" is invalid: spec.ports[0].appProtocol: Forbidden: This field can be enabled with the ServiceAppProtocol feature gate


To fix this issue, you can simply find and comment out this line in the Service definition files:

appProtocol: https

With OpenShift, you can define a PassThrough Route to let Zowe handle TLS connections.
