Webroot env variables not consistent

[joshuata]

The instructions for docker deployment say to set the WEB_ROOT variable when deploying, however this does not rebuild the app, so none of the static assets are available. This can be avoided by setting webroot so that the run.sh script picks it up and rebuilds the app. This can be avoided by using the same variable in both places.

Also, this looks like it might be an issue with all similar env vars in the alpine/run.sh file

Thank you for this, I was struggling to understand why my assets were not under the specified web root.
