Troubleshooting
POD Does Not Start
Sometimes a POD could be stuck in a CrashLoopBackOff
state and it is not obvious what happened behind this error. To understand the root cause, use the following command with the -p
option to inspect the previous failed state:
kubectl logs -p <pod name> -n apache-ignite
Inspecting Operator Logs
For debugging common issues, inspect the operator’s pod logs. You can retrieve a pods list by using the following command, assuming that the operator is deployed and running:
kubectl get pods -n <operator-namespace>
NAME READY STATUS RESTARTS AGE
apache-ignite-operator-868fb8bdcd-46xnh 1/1 Running 0 8d
Knowing a running pod’s name, you can inspect the pod logs by using the following command:
kubectl logs apache-ignite-operator-868fb8bdcd-46xnh -n <operator-namespace>

PLAY RECAP *********************************************************************
localhost : ok=0 changed=0 unreachable=0 failed=1 skipped=14 rescued=0 ignored=0
The <operator-namespace>
is apache-ignite-operator
by default.
Missing Default StorageClass
If you notice the following error in the logs, either add a default StorageClass or configure StorageClass manually by referring to the Storage configuration section.
TASK [create-statefulset : fail] *********************************************************************************************************
fatal: [localhost]: FAILED! => {"changed": false, "msg": "The system is unable to locate StorageClass with name 'myClassName'"
