I’m hitting a bit of a wall with a seemingly trivial Docker image build. I have a Go binary target which I’m trying to toss into a Docker image, and when running

pants package

I get the following out of the subprocess stderr:

ERROR: use `docker --context=default buildx` to switch to context "default"

I’m not seeing much in the pants log that looks weird, and a cursory google search suggests that this problem is normally related to the

DOCKER_HOST

or

DOCKER_CONTEXT

env vars. I’m using pants v.216.0, and docker desktop on OSX; v4.21.1 (docker engine 24.0.2). Here’s a

-ldebug

full output: https://gist.github.com/jcrumb-u21/b2836d74bd70d551f0b06ee90e2aaf19 and my full Dockerfile: https://gist.github.com/jcrumb-u21/dd907855b89fa6730e55fb27f829d1f4. I can see that the dependency inference is working and my Go binary is being built at least which is pretty sweet!

This happened to me when I updated my Docker. When I downgrade it to 4.20.1 worked normally, as far as I can recall.

Yeah, that’s worked for me as well. Engine version didn’t change, so it must be something about Docker Desktop itself. Classic.

This happened to me, too. I fixed it by running

docker context use default

. Seems like a change introduced by docker.

Good tip; that fixed the issue for me on 4.21.1 as well (our MDM automatically upgraded my Docker again in the background 🙄)
