Code change:
Kubelet now only reports ContainerStatus. PodStatus / PodCondition is observed at master side based on a set of ContainerStatus. There is no other way to get PodIP except net container for master side. This is very confusion to the end user, , , ... Now we are finalizing on v1beta3 API, including PodStatus & ContainerStatus. We can make net container completely invisible to the end users by finishing the following steps: 1) Expose network related errors at API level 2) Generate PodStaus directly from Kubelet
3) once PodStatus generated by kubelet, PodIP can be removed from ContainerStatus.
I think reporting PodStatus rather than just container status is most important. How hard is that?
Used to be hard since there are many dependencies when I first report Status back. Now it is totally feasible. I already started to write PRs for this. :-)
One more PR required to close this one.
