# Dynamically constructed Dockerfile This folder builds a runtime image (sandbox), which will use a dynamically generated `Dockerfile` that depends on the `base_image` **AND** a [Python source distribution](https://docs.python.org/3.10/distutils/sourcedist.html) that is based on the current commit of `openhands`. The following command will generate a `Dockerfile` file for `nikolaik/python-nodejs:python3.12-nodejs22` (the default base image), an updated `config.sh` and the runtime source distribution files/folders into `containers/runtime`: ```bash poetry run python3 openhands/runtime/utils/runtime_build.py \ --base_image nikolaik/python-nodejs:python3.12-nodejs22 \ --build_folder containers/runtime ```
