This is a two site installation, with a single cassandra container,  two mariadb containers, and two mdbc-server containers.

Server 1 exposes port 30001 and server 2 exposes port 30002.

To build the docker images, first build mdbc software normally, then use the 'docker' maven profile:

mvn -P docker clean install

To bring up the environment:

cd mdbc-packages/mdbc-docker/compose/two-sites

docker-compose up
