Hmm, I'm rethinking if we should be merging these flags together. I think we should still support both of these flags, but when we're using the benchmark runner in maxtext, we should support Pathways being able to use |

Why do we need distinction between cloud and local images? What if I push my local ubuntu image to gcr and want to use it as a local image? It will be treated as a cloud image.

You are right. It should be based on the flag --script-dir
I will update it and verify again

There was a problem hiding this comment.
It is updated to check --script-dir and is_cloud_image to determine if building a new image is needed.
I attached the commands and logs below

Why do we need this is_cloud_image check at all? IMO this is completely wrong, as if I as a researcher store my image outside of GCP I might still want to build scripts right?
There was a problem hiding this comment.
The original purpose of is_cloud_image is to check if it is a local image, if so, we need to push the local image to cloud for pods to pull.
if (
args.script_dir and args.script_dir != DEFAULT_SCRIPT_DIR
) or not is_cloud_image:
validate_code = validate_docker_image(docker_image, args)
if validate_code != 0:
xpk_exit(validate_code)
build_code, docker_image = build_docker_image_from_base_image(args)
if build_code != 0:
xpk_exit(build_code)
And you are right, it will force the user to build and push the image if the image is outside of GCP.
I will update it. Thanks for the review!

@scaliby I updated the logic and please review it one more time.

@scaliby can you please review this PR again? |

It's very hard for me to see all of the consequences of merging these two flags, as I'm not familiar with all of the usage cases enough (yet). Is merging of these flags just for convenience / simplification, or is there another reason to do it? |
