ningyougang opened a new issue #652:
URL: https://github.com/apache/openwhisk-deploy-kube/issues/652
If the number of prewarm runtime pods is low, after executed `helm delete(or
uninstall) xxx`, all prewarm runtime pods are deleted completely.
But if the number of prewarm runtime pods is big, after executed `helm
delete(or uninstall) xxx`, some prewarm runtime pods are not deleted
completely.(e.g. maybe 1/3 prewarm pods are deleted, 2/3 prewarm pods are not
deleted, still Running)
The reason is
After analized the kubernets-client-4.4.2.jar source codes, when invoke
below codes
```
kubeRestClient
.inNamespace(kubeRestClient.getNamespace)
.pods()
.withLabels(labels.asJava)
.delete()
```
Finally, it will invoke below codes
We can see, it deletes the runtime pods in a for statement, on the other
hand, `h.delete(client, ...)` method is a sync method, due to some
configuration of timeout is low, it leads to can't delete all runtime pods
I will open 2 prs to solve this issue
