There was a problem hiding this comment.
I still think theres a race condition here. Haven't been able to reproduce it yet but I do think it exists. The pod can be modified and send an event, but the container hasn't restarted yet. I don't believe that it happens atomically.
The outer loop will retry each time a pod is Modified and the code makes sure a container is not logged twice. Signed-off-by: David Gageot <david@gageot.net>

@r2d4 I believe a watch event will always be received each time a pod's container is actually started. And from that point, the logs can be attached. |
