Description

For example, in the following process:

• use mvn (as currently) to create a WAR file, with the pom.xml set up for JDBC drivers of all DB servers we might want to connect to (hsqldb, sql server, postgresql)
• the Docker image should be built from a Dockerfile specifying just Tomcat 8 + Java 8.
• the build process that creates the Docker image should explode the WAR file, and not copy over the WAR. Ideally these files should be read-only
• for externalizing configuration, develop an ENTRYPOINT script that gather up all the command line arguments passed to docker run and copy them into a new WEB-INF/overrides.properties file; Apache Isis will be enhanced to pick this up if present
