starting the `./build-docker.sh` script (or using your own docker build
solution).
### Passing arguments to Docker
When the docker image is run various required command line arguments are provided. For example the system mounts the `/dev` directory to the `/dev` directory within the docker container. If other arguments are required they may be specified in the PIGEN_DOCKER_OPTS environment variable. For example setting `PIGEN_DOCKER_OPTS="--add-host foo:192.168.0.23"` will add '192.168.0.23 foo' to the `/etc/hosts` file in the container. The `--name`
and `--privileged` options are already set by the script and should not be redefined.
