Expose raw API calls for logs, exec, etc.

I would love the ability to send commands to running pods. Would solve a lot of problems for me. Big thumbs up!

I'm actually struggling to find a spec on how attach is implemented. Do you have any links in the core repo?

[chancez]

They have their own protocol built on top of http2, most of the core pieces are in k8s.io/apimachinery/pkg/util/httpstream for how they do the protocol negotiation/versioning and the actual http2 bits. k8s.io/kubernetes/pkg/client/unversioned/remotecommand has the protocol on top.

In addition there is a WebSocket variant since 1.6, if that is easier to support.

@chancez to the best of my understanding it's a SPDY upgrade, not HTTP/2.

@sttts since this client enables HTTP/2 I don't think Go will let the API server hijack the connection and switch to websockets.[0]

Maybe upstream would accept the PRs if I could get exec working over an HTTP/2 stream? :)

Did exec over an HTTP/2 stream end up working?

[ericchiang]

This is still open. I haven't had time to dig into how much work it'd be to support, and a lot of the deployments patterns I personally use don't leverage exec.
