Offline installation

[kixxalot]

When dealing with sensitive datasets, the users and machine running Arcade may be on a sublan disconnected from the net by a firewall. In that case it would be great if there was a way to install Arcade on a machine without requiring internet.

(Obviously the current way of running Arcade via Docker does require net access upon the first startup, as Docker will then try and download required files that are not yet in its cache)

Note: this is possible by:

1. running the docker-compose command on a machine with internet access,
2. saving the 4 created docker images one by one, via e.g. docker save arcadeanalytics/arcadeanalytics > arcadeanalytics.tar
3. transferring these images to the machine without net access,
4. loading the images via e.g. docker load < arcadeanalytics.tar
5. start the app with the docker-compose command, which now does not need to pull anything from the net anymore

However, it seems that like this the web UI port 8080 cannot be changed. Please correct me if I'm wrong.

you can change the mapping inside the compose as you prefer:

    ports:
      - 8080:8080
