nemo_gym.tasks.harbor.dockerfile

Recognize Dockerfiles that only name a base image.

Many tasks ship a Dockerfile that is FROM <image> plus WORKDIR, ENV, USER or LABEL lines. Nothing in such a file changes the filesystem, so Gym can run the base image directly and apply the recorded settings at sandbox creation instead of building. Anything else (RUN, COPY, ADD, multi-stage builds, ARG-templated images) needs a real build, which is not part of this loader yet.

nemo_gym.tasks.harbor.dockerfile._logical_lines(
    text: str
) -> list[str]

Join continuations without inventing whitespace; drop comments and blanks.

nemo_gym.tasks.harbor.dockerfile._parse_env(
    arguments: str
) -> dict[str, str] | None

nemo_gym.tasks.harbor.dockerfile.base_image_only(
    text: str
) -> nemo_gym.tasks.harbor.dockerfile.BaseImage | None

Return faithfully interpreted settings, or None when a build is needed.

Variable expansion and relative working directories depend on the base image’s configuration. Leave those to a real build until that configuration is available.
