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
// Retrieves running pods
$ oc get pods
NAME READY STATUS RESTARTS AGE
kogito-operator-6d7b6d4466-9ng8t 1/1 Running 0 26m

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
apiVersion: rhpam.kiegroup.org/v1 # Red Hat build of Kogito API for this microservicekind: KogitoRuntime # Application typemetadata:name: example # Application namespec: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:
