Binary-Output-Path since GOAMD64

[ckotzbauer]

Hi all,

I have a question regarding the latest Go 1.18 GOAMD64 feature and its implementation in goreleaser.

This has changed the output path of the compiled binary from e.g. dist/my-project_linux_amd64/my-project to dist/my-project_linux_amd64_v1/my-project for amd64. This _v1 suffix is only added for the amd64 target by design. But this makes it difficult to access the file from a Dockerfile (not built with goreleaser) in the next step: COPY dist/my-project_${TARGETOS}_${TARGETARCH}/my-project /usr/local/bin/my-project. This will now fail for an amd64-Image build but succeed for e.g. arm64.

Is there a solution to access the files from the Dockerfile without splitting them to amd64 and non-amd64?

Note: The reason not to build the images with goreleaser too is the missing buildx-support.

Thanks a lot! 🥳

My config files for goreleaser and the Github Action which builds the image:

.goreleaser

    - go mod tidy

COPY dist/my-project_${TARGETOS}_${TARGETARCH}/my-project /usr/local/bin/my-project

doesn't

COPY dist/my-project_${TARGETOS}_${TARGETARCH}*/my-project /usr/local/bin/my-project

works?

[ckotzbauer]

Well, sometimes the answer is too easy 😆 🙈

Another approach would be to parse dist/artifacts.json somewhere and use the paths from there
