Hey peeps! Pantsbuild no longer wants build Docker images, and just returns this strange message from Docker which I cannot figure out with googling. Any help?

I have not seen anything like it either but surface googling says it would be good to see 
docker context ls
output as a start as well as what 
DOCKER_*
env vars you normally have set in your environment vs what 
DOCKER_*
env vars you explicitly punch through Pants via 
pants.toml
and/or 
BUILD
files.

Hey John! Thank you for reaching out so quickly, much appreciated.

I am on pants 2.16. Not passing in anything else to Docker methinks.
I can try explicating the DOCKER_CONTEXT by using env variables, just waiting for a build to finish.
I recently updated Docker, not sure if that is what's causing this. I cannot think of any other change that could have caused this to start happening.

Ok. One thing to point out, screen shots are extremely support unfriendly since text is unselectable.
f
Ah, that's a good point. Do you want me to repost the above or is it OK?
e
But clearly try poking through 
DOCKER_HOST=...
That default value.
Since the default is not the default per your 
ls
output.
f
Aha, good point! I'll try that and get back to you.
Alright, it works now! What fixed is was setting the docker context back to default using 
docker context use default
. I am not super familiar with Docker contexts, so I'm not sure why this would cause an issue. But there's your fix for the next person with the same problem!

Also just hit this. Pasting the error for future search.
Copy code
ERROR: use `docker --context=default buildx` to switch to context "default"
Reproducible with example-docker repo by running 
pants package src/docker/hello_world:shell
. Will dig into it some more.
