saffronjam opened a new issue, #6456:
URL: https://github.com/apache/cloudstack/issues/6456
##### ISSUE TYPE
* Bug Report
##### COMPONENT NAME
API
##### CLOUDSTACK VERSION
4.17.0 (cloud have occurred on 4.16.1)
##### CONFIGURATION
Single host running management server and database
##### OS / ENVIRONMENT
Ubuntu 20.04
##### SUMMARY
When attempting to delete a Kubernetes cluster, it gets stuck in Stopping
state.
And every time a kubernetes-related API call is made, such as
"deleteKubernetesCluster", error 530 appears
Investigating the cloudstack-management.service logs, there seem to be an
unhandled null pointer exception when issuing some string operation (perhaps a
toString() on a null reference). Looking into the source code, it appears to be
the case.
##### STEPS TO REPRODUCE
Removing clusters was possible, but this time it appears as some reference
was deleted in database, which nullified a field in a row in the table
kubernetes_supported_version, or related table. Therefore, it would be hard to
write steps to reproduce.
##### EXPECTED RESULTS
Friendlier error message, recoverable state. How can such a field become
null?
##### ACTUAL RESULTS
Kubernetes clusters stuck in stopping state, refuses to be deleted,
prompting multiple error code 530 messages
(every delete operation is ignored since a cluster cannot be deleted while
in the stopping state)
