This PR needs a bit of re-work. The script as is will always complete and return false positives.

This is not sufficient. condition.type
tells you if the status condition is reporting the Complete
or Failed
. The Complete
and Failed
condition types should always be populated in the Conditions
array.
You need to inspect the condition.status
field, which can be True
, False
, or Unknown
.

This is probably where the bug is. Per the Job API documentation:
completionTime(Time):
Represents time when the job was completed. It is not guaranteed to be set in happens-before order across separate operations. It is represented in RFC3339 form and is in UTC. The completion time is set when the job finishes successfully, and only then. The value cannot be updated or removed. The value indicates the same or later point in time as the startTime field.
I suspect that in your case, the job is failing. This script doesn't see a completion time because the Job
never succeeds, hence it just runs forever.
See https://kubernetes.io/docs/reference/kubernetes-api/workload-resources/job-v1/#JobStatus
Changes
hack/storage-version-migration.sh
script is mentioned in the install steps. If that script is executed it runs infinitely without reporting any success or failure. This PR adds changes to put checks inhack/storage-version-migration.sh
script to give success or failure response and terminate the execution in finite time.Fixes #1680
