The Dockerfile now works as expected

Dockerfile

 # Since we are including resources from the parent folder,
 # this Dockerfile has to be executed from the project's parent folder, like this:

+
+## Challenge: database connection to "localhost" ?? IP address? What?? :-)
 
 # the first stage of our build will use a maven 3.6 parent image

 # Building VIPSLogic
+## But first: A deployment note
+Whether you deploy using Docker or Wildfly (or another JEE server), the context path of the app is always /VIPSLogic. However, the app is designed to be accessible at the root level. So you always need to proxy it behind e.g. Apache or Nginx. Here's an example vhost for Apache:
+
+```
+<VirtualHost *:80>
+        ServerName vipslogic-local.no
+
+        AddDefaultCharset UTF-8
+
+        ProxyPass               /       http://localhost:18080/VIPSLogic/
+        ProxyPassReverse        /       http://localhost:18080/VIPSLogic/
+        ProxyPassReverseCookiePath      /VIPSLogic /
+</VirtualHost>
+
+```

+
+Run

 VIPSLogic is using system properties for instance specific settings. In Wildfly (JBoss), these can be provided
