Introduce ContainersReady condition in Pod Status

/assign yujuhong for review
/assign thockin for the tiny API change

dixudx

Mostly lgtm. Some nits.

Moreover, lastTransitionTime is missing for new PodConditionType ContainersReady. You have to
add updateLastTransitionTime(&status, &oldStatus, v1.ContainersReady) in method updateStatusInternal (pkg/kubelet/status/status_manager.go).

combine L266 with L269? So we can have one return -1, nil.

change to 27?

Better add a comment for this.

Like, "preserve non-system condition types". WDYT?

@freehan could you remove the readiness gate commits from this PR?

Not sure why the add ReadinessGates in pod spec commit is in this PR...

Because it was not merged at the time...

Thanks @freehan and @yujuhong

So, is this PR required if the other PodReady PRs merge?

You need some more labels here:

/sig network
/priority important-soon

freehan · 2018-06-05T18:25:30Z

So, is this PR required if the other PodReady PRs merge?

Yes. This PR completes the proposal.

colemickens · 2018-06-05T20:54:03Z

Hey folks, from the comments, it sounds like this is desired for 1.11, but it's not labeled correctly for that to happen, and there are additional labels needed if it doesn't merge today before the beginning of code freeze. Please ensure the labels for the milestone and urgency are set correctly.
