| Execute a command inside a Singularity container |
| |
| Singularity has more seamless connection to the host than Docker, so |
| no special binds are needed to ensure binding content in the user $HOME |
| and temporary directories. If the user needs custom binds, this can |
| be done with --volumes |
| |
| :param image: Singularity image or URI from which to create the container. |
| :type image: str |
| :param auto_remove: Delete the container when the process exits |
| The default is False. |
| :type auto_remove: bool |
| :param command: Command to be run in the container. (templated) |
| :type command: str or list |
| :param start_command: start command to pass to the container instance |
| :type start_command: string or list |
| :param environment: Environment variables to set in the container. (templated) |
| :type environment: dict |
| :param working_dir: Set a working directory for the instance. |
| :type working_dir: str |
| :param force_pull: Pull the image on every run. Default is False. |
| :type force_pull: bool |
| :param volumes: List of volumes to mount into the container, e.g. |
| ``['/host/path:/container/path', '/host/path2:/container/path2']``. |
| :param options: other flags (list) to provide to the instance start |
| :type options: list |
| :param working_dir: Working directory to |
| set on the container (equivalent to the -w switch the docker client) |
| :type working_dir: str |
