Hey folks! What's the right way to build this locally? I'm on a Mac but can spin up a VM as needed.

Do you want to build images? You can use the Makefile, eg make retina-image

@rbtr Likely an issue on my end, but perhaps you've seen these before?

This problem with compiling the binary is likely due to your host platform not being supported by this package (only Linux and Windows build constraints are supported):

Does anything change if you set env vars for GOOS=linux, GOARCH=amd64? I don't have access to a Mac to test but @vakalapa is going to be checking another issue and might be able to test this also.

No such image: moby/buildkit:buildx-stable-1

This one I am more confused about, as that is a Moby infra image that should definitely exist...not sure how to fix this 🤔

WARNING: No output specified with docker-container driver. Build result will only remain in the build cache. To push result image into registry use --push or to load image into docker use --load

Is resolved by adding a BULIDX_ACTION such as make retina-image BUILDX_ACTION=--load
