Digging deeper into ready.py, wait_for_statefulset_complete has this condition:
===
s = response.status
if (s.updated_replicas == response.spec.replicas and
s.replicas == response.spec.replicas and
s.ready_replicas == response.spec.replicas and
s.current_replicas == response.spec.replicas and
s.observed_generation == response.metadata.generation):
log.info("Statefulset " + statefulset_name + " is ready")
return True
===
but when I check on the info provided by kubectl:
===
# kubectl -n onap get statefulset/dev-cassandra-cassandra -o yaml
...
status:
collisionCount: 0
currentReplicas: 3
currentRevision: dev-cassandra-cassandra-84f4d86c9f
observedGeneration: 1
readyReplicas: 3
replicas: 3
updateRevision: dev-cassandra-cassandra-84f4d86c9f
===
The status section does not include an "updated replicas" value. Does that mean
it would be null in the ready.py script?
Should the readiness-check fail when 4 out of 5 conditions are met and the
other condition is null?
This issue appears to be related to
https://github.com/kubernetes/kubernetes/issues/52653
So, does anyone know how to get an "updated replicas" value in the status?
I am guessing that a spurious kubectl scale command would be enough of an
update, but is there any better recommendation?
Thanks,
Keong
