There was a problem hiding this comment.
After it's extracted to a method and called separately, it doesn't wait for cache to sync, I think it may miss Pod data?
Add a retry mechanism in the Controller initialization, which will keep trying to sync iptables rules until the operation is successful. On success, the NPL Controller is notified through a channel and can start its event handlers. Fixes antrea-io#2554 Signed-off-by: Antonin Bas <[email protected]>

@tnqn thanks for the review. I believe you are right about the cache. I pushed a second commit to address it. Please let me know if you have a more elegant solution to suggest. |
