BuildFromImageType Objects​

class BuildFromImageType(Enum)

SCRATCH​

Slowest: Build from base image (no dependencies are reused)

VERSIONED​

Medium speed: Reuse the most recent image with the same base image & OH version (a lot of dependencies are already installed)

LOCK​

Fastest: Reuse the most recent image with the exact SAME dependencies (lock files)

get_runtime_image_repo_and_tag​

def get_runtime_image_repo_and_tag(base_image: str) -> tuple[str, str]

Retrieves the Docker repo and tag associated with the Docker image.

Arguments:

  • base_image (str): The name of the base Docker image

Returns:

  • tuple[str, str]: The Docker repo and tag of the Docker image

build_runtime_image​

def build_runtime_image(base_image: str,
                        runtime_builder: RuntimeBuilder,
                        platform: str | None = None,
                        extra_deps: str | None = None,
                        build_folder: str | None = None,
                        dry_run: bool = False,
                        force_rebuild: bool = False,
                        extra_build_args: List[str] | None = None) -> str

Prepares the final docker build folder. If dry_run is False, it will also build the OpenHands runtime Docker image using the docker build folder.

Arguments:

  • base_image (str): The name of the base Docker image to use
  • runtime_builder (RuntimeBuilder): The runtime builder to use
  • platform (str): The target platform for the build (e.g. linux/amd64, linux/arm64)
  • extra_deps (str):
  • build_folder (str): The directory to use for the build. If not provided a temporary directory will be used
  • dry_run (bool): if True, it will only ready the build folder. It will not actually build the Docker image
  • force_rebuild (bool): if True, it will create the Dockerfile which uses the base_image
  • extra_build_args (List[str]): Additional build arguments to pass to the builder

Returns:

  • str: <image_repo>:<MD5 hash>. Where MD5 hash is the hash of the docker build folder

See https://docs.all-hands.dev/modules/usage/architecture/runtime for more details.

truncate_hash​

def truncate_hash(hash: str) -> str

Convert the base16 hash to base36 and truncate at 16 characters.
