Hi folks! I am building a Docker image using Pants on an M1 Max Mac machine using Colima as the backend. When I run

pants package /path/to/Dockerfile

, I get:

11:45:59.60 [ERROR] 1 Exception encountered:

Engine traceback:
  in `package` goal

ProcessExecutionFailure: Process 'Building docker image docker:latest' failed with exit code 1.
stdout:

stderr:
ERROR: no builder "colima" found

But when I run

docker buildx ls

on the machine, I get:

$ docker buildx ls
NAME/NODE DRIVER/ENDPOINT STATUS  BUILDKIT PLATFORMS
colima *  docker
  colima  colima          running 20.10.20 linux/arm64, linux/amd64

and

docker buildx use colima

seems to work fine:

$ docker buildx use colima

Is there something I’m missing here / some reason Pants can’t find the

colima

builder?

It looks like there is no buildx support: https://github.com/pantsbuild/pants/issues?q=is%3Aissue+is%3Aopen+buildx

Ah, I should have checked Github as well. Thanks for the pointer! I assume this means that on Mac, the only way to build is to install the official Docker Desktop?

No clue - I don't use a Mac.

All good. Thanks anyways!
