Overriding Go values with ldflags

Posted on 2022-08-12

You can override Go values with ldflags during the build.

That way, you can inject values like the current version, build date or the current commit hash.

go build \
    -ldflags "-X 'github.com/metal-stack/v.Version=$(VERSION)' \
              -X 'github.com/metal-stack/v.Revision=$(GITVERSION)' \
              -X 'github.com/metal-stack/v.GitSHA1=$(SHA)' \
              -X 'github.com/metal-stack/v.BuildDate=$(BUILDDATE)'" \

Seen in the metal-stack/v repository.
