Got a good high level and some detail view but given the complexity of the custom hooks, more pictures and detailed flows would always help than words. Thanks for presenting such a non-trivial topic.
"mutating webhooks are called serially, one after the other" - So in case of multiple mutating webhooks is there some logic behind order in which they will be get called?

Hi @CNCF wanted to check why the video was moved from its original link of ruclips.net/video/bMmYwvtYIZc/видео.html ?
Thanks a lot this was useful and the way you explained was appreciable :)
