@ArangoGutierrez i see that the samples binaries are getting built from here https://github.com/NVIDIA/k8s-samples/blob/main/deployments/container/Dockerfile.ubuntu#L38

which means i can just add the simpleMultiGPU sample in the CI yaml and it will be built automatically. All the dockerfile seems to be archived and only for reference.

Thanks @guptaNswati. This looks good.

I noted that for "sample only tag" we're pushing: ghcr.io/nvidia/k8s-samples:devicequery-b5b1a425- for example which is not specific to this PR. Going to approve this and then we can have a look at what's going on there as a follow-up.

update: I take it back. It's line wrapping in the CI output. The string is being split on the - and the full string is actually:
