The help for launcher has
```plaintext
Usage: launcher COMMAND CONFIG [--skip-prereqs] [--docker-args STRING]
Commands:
start: Start/initialize a container
...
start-cmd: Generate docker command used to start container
...
```
and since I know `launcher` is at times issuing [Docker container commands](https://docs.docker.com/engine/reference/commandline/container/) I was expecting `start-cmd` to show the Docker command with all the parameters to start the container.
This was the result
```plaintext
groot@galaxy:/var/discourse$ ./launcher start-cmd
Usage: launcher COMMAND CONFIG [--skip-prereqs] [--docker-args STRING]
Commands:
start: Start/initialize a container
...
```
a dump of the command help.
How is this command used?

You still need to give it the config for which to issue the command, e.g.: `./launcher start-cmd app`

Obviously specific values were sanitized.
