#6460 [Core feature] fast-fail inamgespec Issue created by dansola Motivation: Why do you think this is important? Right now, if

ImageSpec

can't find or create an image (e.g. Docker isn't running), it assumes the image exists with

f"Flytekit assumes the image {img_name} already exists."

. For CI/CD processes, it may not be ideal for an automated system to assume an image exists. Goal: What should the final outcome look like, ideally? Ideally, the

register

or

run

command can take a

--imagespec-fast-fail

flag which will fail the registration or run command if the image can't be built. Describe alternatives you've considered Alternatively,

ImageSpec

could take an argument that prevents registration from succeeding if the image can't be found or built. Propose: Link/Inline OR Additional context Proposition: 1. Add a

--imagespec-fast-fail

flag 2. Add a

imagespec_fast_fail

argument to

ImageConfig

which is included in the

SerializationSettings

during registration. 3. In

ImageBuildEngine.build

, include the

imagespec_fast_fail

arg. 4. In

ImageSpec

, in

should_build

, raise an error if

imagespec_fast_fail==True

and the image can't be found or built. Are you sure this issue hasn't been raised already? • Yes Have you read the Code of Conduct? • Yes flyteorg/flyte
