Hi to all! I just joined the slack, really nice to know the community here 🙌 I have some questions regarding pants + docker. I’m using M1 Mac, and am tying to build docker image with multi-platform support. I can do this with something like

docker buildx build --push --platform linux/arm64,linux/amd64

, but with pants,

[docker]
build_args = [
  "--no-cache=true",
  "--platform=linux/arm64,linux/amd64"
]

the above configuration doesn’t seem work at all, no errors, no effects. I’m wondering is that a configuration error or something else?

build_args

refers to the

--build-arg

specifically, not a general set of command line arguments to pass to

build

(confusing), see https://www.pantsbuild.org/docs/reference-docker#build_args. For the specific example of platform, there's https://github.com/pantsbuild/pants/issues/17539
