Build arm64 zot image

[srinivassrini]

Hi Team,
I'm trying to build arm64 zot image but dockerfile have golang image only supports to amd64. i need arm64 golang image. or any way i can build fips arm64 zot image with -extldflags=-static linked?

Hi, our makefile uses CGO_ENABLED=0 GOOS=$(OS) GOARCH=$(ARCH) in the go build command, so it builds cross-platform static binaries without CGO this way.

Now, in the specific case of fips, there's this go enhancement which theoretically does not need C, which I haven't tried and I don't know if it fits in your use case.

If you want to use CGO, https://hub.docker.com/_/golang specifies multiple architectures.

Hi @andaaron,
If i use golang-alpine:1.24 or golang:1.24. for both arm64 and amd64 build is failing with below error. Any wrong in this line of code?

line number 172 have this code:
env CGO_ENABLED=1 GOEXPERIMENT=boringcrypto GOOS=$(OS) GOARCH=$(ARCH) go build -o bin/zot-$(OS)-$(ARCH) $(BUILDMODE_FLAGS) -tags $(BUILD_LABELS),containers_image_openpgp -v -trimpath -ldflags "-linkmode=external -extldflags=-static -X zotregistry.dev/zot/pkg/api/config.ReleaseTag=$RELEASE_TAG -X zotregistry.dev/zot/pkg/api/config.Commit=$COMMIT -X zotregistry.dev/zot/pkg/api/config.BinaryType=$(extended-name) -X zotregistry.dev/zot/pkg/api/config.GoVersion=$GO_VERSION -s -w" ./cmd/zot
