Katib image build failed because of Golang version

/kind bug

What steps did you take and what happened: Trying to build the katib image, I’m getting the following error:

Step 27/32 : RUN CGO_ENABLED=0 GOOS=linux GOARCH=${TARGETARCH} go build -a -o katib-ui  ./cmd/new-ui/v1beta1

The command '/bin/sh -c CGO_ENABLED=0 GOOS=linux GOARCH=${TARGETARCH} go build -a -o katib-ui  ./cmd/new-ui/v1beta1' returned a non-zero code: 2

I also tried docker build . -f cmd/new-ui/v1beta1/Dockerfile -t ${IMG}:${TAG} --no-cache in case of having an older golang image cached but the error persists.

@tenzen-y @johnugeorge thank you very much for you help!

In the end we got to the bottom of it and it was indeed an issue with the cache and golang:alpine. The problem was that we had fetch the golang:alpine previously, when it didn’t have Golang 1.19, and now when building the image it wouldn’t re-pull it.

We also misunderstood how --no-cache works. This argument tells docker to not use a cached LAYER when building the image. But this will not affect the base images with FROM <image>. For this they have the --pull argument https://docs.docker.com/engine/reference/commandline/build/#options

So after using the following command we managed to build it successfully

docker build . -f cmd/new-ui/v1beta1/Dockerfile -t ${IMG}:${TAG} --pull

Thanks!
