Hi @rainfd. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

I have one concern not all the flags are in the parameter table(Flags table in FAQ) you mentioned in this PR. I also checked the script locally, it generated the table but not all the flags are there which are mentioned in the CA main.go. One of the flags is nodeDeletionDelayTimeout.

Please let me know if I missed something here.

@Shubham82 Alias node-deletion-delay-timeout is in the definition

nodeDeletionDelayTimeout    = flag.Duration("node-deletion-delay-timeout", 2*time.Minute, "Maximum time CA waits for removing delay-deletion.cluster-autoscaler.kubernetes.io/ annotations before deleting the node.")

nodeDeletionDelayTimeout    = flag.Duration("node-deletion-delay-timeout", 2*time.Minute, "Maximum time CA waits for removing delay-deletion.cluster-autoscaler.kubernetes.io/ annotations before deleting the node.")

Sorry My bad, I forgot to mention the hyphen(-) in the flag name, I have rechecked it locally, and flags are generated from the script.

Thanks!
