DockerRuntimeBuilder Objects

class DockerRuntimeBuilder(RuntimeBuilder)

build

def build(path: str,
          tags: list[str],
          platform: str | None = None,
          use_local_cache: bool = False,
          extra_build_args: list[str] | None = None) -> str

Builds a Docker image using BuildKit and handles the build logs appropriately.

Arguments:

• path str - The path to the Docker build context.
• tags list[str] - A list of image tags to apply to the built image.
• platform str, optional - The target platform for the build. Defaults to None.
• use_local_cache bool, optional - Whether to use and update the local build cache. Defaults to True.
• extra_build_args list[str], optional - Additional arguments to pass to the Docker build command. Defaults to None.

Returns:

• str - The name of the built Docker image.

Raises:

• RuntimeError - If the Docker server version is incompatible or if the build process fails.

Notes:

This method uses Docker BuildKit for improved build performance and caching capabilities. If use_local_cache is True, it will attempt to use and update the build cache in a local directory. The extra_build_args parameter allows for passing additional Docker build arguments as needed.

image_exists

def image_exists(image_name: str, pull_from_repo: bool = True) -> bool

Check if the image exists in the registry (try to pull it first) or in the local store.

Arguments:

• image_name str - The Docker image to check (<image repo>:<image tag>)
• pull_from_repo bool - Whether to pull from the remote repo if the image not present locally

Returns:

• bool - Whether the Docker image exists in the registry or in the local store
