a --strict mode for build?

[monopole]

Such a mode would advise user about poor idioms YAML, or features about to be deprecated,

Kustomize build outputs yaml syntax failures and deprecation messages. Not necessary to have one more mode for showing those.

My use case for --strict would be in a CI environment to fail the build if Kustomize returns any errors. Without this flag, is there a way I can accomplish this?

[Liujingfang1]

You can check the exit code of kustomize build. When it is non zero, you can set the CI build to fail.

Ah, my builds continued on even with the failure so I had assumed it was returning a 0 exit code. I see now that it's 1. Thank you!
