Chapter 15. Red Hat build of Kogito microservice deployment troubleshooting

Use the information in this section to troubleshoot issues that you might encounter when using the operator to deploy Red Hat build of Kogito microservices. The following information is updated as new issues and workarounds are discovered.

No builds are running

If you do not see any builds running nor any resources created in the relevant namespace, enter the following commands to retrieve running pods and to view the operator log for the pod:

View RHPAM Kogito Operator log for a specified pod

// Retrieves running pods
$ oc get pods

NAME                                     READY   STATUS      RESTARTS   AGE
kogito-operator-6d7b6d4466-9ng8t   1/1     Running     0          26m

// Opens RHPAM Kogito Operator log for the pod
$ oc logs -f kogito-operator-6d7b6d4466-9ng8t

Verify KogitoRuntime status

If you create, for example, KogitoRuntime application with a non-existing image using the following YAML definition:

Example YAML definition for a KogitoRuntime application

apiVersion: rhpam.kiegroup.org/v1 # Red Hat build of Kogito API for this microservice
kind: KogitoRuntime # Application type
metadata:
  name: example # Application name
spec:
  image: 'not-existing-image:latest'
  replicas: 1

You can verify the status of the KogitoRuntime application using the oc describe KogitoRuntime example command in the bash console. When you run the oc describe KogitoRuntime example command in the bash console, you receive the following output:

Example KogitoRuntime status
