Note that there are some pitfalls when using docker:
- If you need to interact with a server listening on the host's loopback network, you must specify the host as `host.docker.internal` instead of `localhost` (for Mac or Windows) _OR_ have the container use the host network with `-network="host"` (Linux only).
- If you need to provide proto source files or descriptor sets, you must mount the folder containing the files as a volume (`-v $(pwd):/protos`) and adjust the import paths to container paths accordingly.
- If you want to provide the request message via stdin, using the `-d @` option, you need to use the `-i` flag on the docker command.
