   Hi @lewismc! Sorry, it took longer to get back...
   
   Finally found, why server and webapp didn't work (`docker prune` didn't 
help):
   - the environment variables `SERVER_HOST`, `SERVER_PORT` and `WEBAPP_PORT` 
were defined but empty
   - after some trial I've discovered that [ARG instructions must be within the 
FROM block they are used 
in](https://docs.docker.com/engine/reference/builder/#understand-how-arg-and-from-interact).
 After moving the ARG lines into the right places (aebf682) I was able to start 
the server. Could you verify this solution?
   
   Another point: after the webapp was moved into separate repository (see 
NUTCH-2886), it needs to be installed separately in the Dockerfile. Right now 
it fails with:
   ```
   ==> /var/log/supervisord/nutchwebapp_stderr.log <==
   Error: Could not find or load main class webapp
   Caused by: java.lang.ClassNotFoundException: webapp
   ```

>          Issue Type: Improvement
>          Components: docker, nutch server, web gui
>    Affects Versions: 1.18
>            Reporter: Lewis John McGibbney

> Some conditional logic and some Docker build arguments would allow a user to 
> run the nutch server alone or both the nutch server and webapp as long 
> running services.
> This could be useful for users who want to remotely interact with Nutch via 
> REST where jobs may actually be executed on yet another remote deployment.
