Discussion:
Currently kubelet reports current status only. If pod's restart policy is not never, the last terminated container status will be override by the latest status, and lost. We should report last terminated container status. I am going to update our v1beta3 api first, but will hold the implementation until we have
did you have a chance to start working on it? IIUC, to support this we need to change the api (), which IIUC from what wrote in some other thread should be done this week. I'm happy to help with it if you want me to help.
Only breaking changes have a deadline. Additive changes can be done at any time.
I am working on this. PR should be ready today or tomorrow.
Also agree with This is not part of API breakage.
Thanks for answers & clarifications and
