- `tag`: The tag/version of the image (default: 'latest')

- `workdir`: The working directory inside the container

- `mount_shared_volume`: Whether to mount a shared volume. Set to False for images that already have content in the workdir (e.g., SWE-bench).

- `ports`: Port mapping from container port to host port. Example: {8080: 8080} maps container port 8080 to host port 8080. Example: {80: 8000, 443: 8443} maps multiple ports.

- **open** — Pull and load a Docker image, then create and start a container.<br/>`open() -> None`

  - `image_name`: The name of the Docker image (e.g., 'ubuntu', 'python')
  - `tag`: The tag/version of the image (default: 'latest')

- **Bash** — Execute a bash command in the running Docker container.<br/>`Bash(command: str, description: str) -> str`

  - `command`: The bash command to execute
  - `description`: A short description of the command in natural language
  - **Returns:** The output of the command, including stdout, stderr, and exit code

- **get_host_port** — Get the host port mapped to a container port.<br/>`get_host_port(container_port: int) -> int | None`

  - `container_port`: The container port to look up.
  - **Returns:** The host port mapped to the container port, or None if not mapped.

- **close** — Stop and remove the Docker container. Handles cleanup of both the container and any temporary directories created for shared volumes.<br/>`close() -> None`
