Support for in cluster kubernetes client

[andrewrynhard]

It seems like buildx explicitly uses the ~/.kube/config. I'd like to run buildx in a CI pipeline that runs in kubernetes. Until #216 is implemented, users are forced to run docker buildx create and need the proper permissions to create deployments. To make doing this easier in a pipeline I'd like to be able to use the permissions of the service account attached to the pod I am running the above command from.

docker/cli#2540 should resolve this once we update the dependencies here.

Same issue and waiting for above PR will be merged, thx!

FYI, I patched like below as a dirty fix (i know it's a vendored code) and worked for me, but i don't understand well why it works.

A tiny bit of topic here
@andrewrynhard I'm looking at achieving same thing but with GitHub actions. So I guess first step would be to have a container with kubectl, helm, tilt and docker+buildx. So instead of reinventing the wheel I ask if you don't happen to have such an image maintained and publicly available?

We do not. Sorry.
