Hi @srajmane. Thanks for your PR.

I'm waiting for a kubernetes-csi member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Corrected syntax for ARCH detection, observed that current code for creating cross build binaries for mentioned architecture is not getting executed.
Updated if condition and verified it manually .

The change itself looks good, I'm just wondering whether should continue to add special build rules like this for different target architectures. Should we just add them for now when people ask for it, or should we stop and try to find a more generic approach, in particular one which then also covers building and publishing of images?

As I don't have the answers for those problems, I myself lean towards simply merging this.

@pohly Thanks for your comments. Yes we are also planning to work on generic images, however for now, adding above would be helpful.

Comment thread build.make
if [ "$(ARCH)" = "amd64" ]; then \
CGO_ENABLED=0 GOOS=windows go build $(GOFLAGS_VENDOR) -a -ldflags '-X main.version=$(REV) -extldflags "-static"' -o ./bin/$*.exe ./cmd/$* ; \
CGO_ENABLED=0 GOOS=linux GOARCH=ppc64le go build $(GOFLAGS_VENDOR) -a -ldflags '-X main.version=$(REV) -extldflags "-static"' -o ./bin/$*-ppc64le ./cmd/$* ; \
CGO_ENABLED=0 GOOS=linux GOARCH=s390x go build $(GOFLAGS_VENDOR) -a -ldflags '-X main.version=$(REV) -extldflags "-static"' -o ./bin/$*-s390x ./cmd/$* ; \

Instead of forcing all developers to build for all of these architectures, let's try something else:

  • by default, build without overriding GOOS and GOARCH
  • add some way (env vars?!) of enabling the building of some other versions of the binaries
  • enable that building in the CI (= prow.sh)

Let me try to come up with such a solution.
