Let's be very explicit in here suggesting that the pod is a full Pod as declared in https://github.com/kubernetes/kubernetes/blob/9343d041209560f487cdf9121d5400a5685fa27a/pkg/apis/core/types.go#L4570 and how the versioning will work.

[matthyx]

do you mean Pod V2 ? (jocking...)
I think we never bothered about versioning the pod spec anywhere, how do you see it?

[SergeyKanzhelev]

We need to explain here where this type is coming from specifically. And the best we can do is to say that the type will be exactly the time for this version of kubelet (not for the version of API server for example).

Also if you can add info on how exactly it will be generated, it will be great

[briansonnenberg]

We're not doing any new generation, just using the existing k8s.io/api/core/v1/generated.proto

import "k8s.io/api/core/v1/generated.proto";

message GetPodResponse {
    k8s.io.api.core.v1.Pod pod = 1;
}

But yes, it will be the latest core Pod API based on the version of Kubelet, so I suppose if you have a different versioned API server and kubelet, they might be serving different messages.

Pod API versioning comment left. And clarify more about the filters
