Hello! I'm currently upgrading from Pants 2.15 to the newest release 2.18. I thought that the Add cache-to and cache-from options pull request was merged on Sep 18, but I can't seem to find those changes in the source code of src/python/pants/backend/docker/goals/package_image.py of the main branch nor the source code of the release_2.18.0 so running

pants publish

docker_image(
    name="with-local-cache-backend",
    cache_to={
        "type": "registry",
        "mode": "max",
        "ref": "[REDACTED]",
    },
    cache_from={
        "type": "registry",
        "ref": "[REDACTED]",
    },
)

Is throwing

InvalidTargetException: src/BUILD:1: Unrecognized field `cache_to={'type': 'registry', 'mode': 'max', 'ref': '[REDACTED]'}` in target [REDACTED]. Valid fields for the target type `docker_image`: ['build_network', 'build_platform', 'context_root', 'dependencies', 'description', 'extra_build_args', 'extra_build_hosts', 'image_labels', 'image_tags', 'instructions', 'output_path', 'pull', 'registries', 'repository', 'restartable', 'secrets', 'skip_push', 'source', 'squash', 'ssh', 'tags', 'target_stage'].

So I'm wondering if I'm missing something or the code isn't there anymore for some reason! Thanks for taking the time to look into this!

It is on

main

still.. but not part of

2.18

release series, as that was cut before that PR was merged. https://github.com/pantsbuild/pants/blob/5cb1a91e32030a87c7aff1a6ea9a646c5470597f/src/python/pants/backend/docker/target_types.py#L325-L382

Perfect thanks for the clarification! Can't wait to see this improve our pipeline building speed 😁

FYI, I have been trying it and the 2.19.0a0 release did not actually work for me and I needed to build from source for get a fix from 2 days ago

yes, that fix will be in the next release candidate.
