Build

To build run:

mvn # with default goals
#  or 
mvn clean install 

Run

To run locally:

java -jar target/hello-world.jar

To run on a VM or Docker container, without a database:

nohup java -jar target/hello-world.jar --spring.profiles.active=local >> server.log 2>&1 &

To run on a VM or Docker container, with a remote database:

nohup java -jar target/hello-world.jar --spring.profiles.active=remote --server.port=XXXX --DB_IP=X.X.X.X --DB_PORT=XXXX --DB_USER=brooklyn --DB_PASS=br00k11n >> server.log 2>&1 &

If not present:

• spring.profiles.active defaults to local (thus all DB_* properties will be ignored)
• server.port defaults to 8080
• DB_IP defaults to localhost (requires a MariaDB containter running on your Docker Runtime, built with the contents if the mariadb-docker directory)
• DB_PORT defaults to 3306
• DB_USER defaults to brooklyn
• DB_PASS defaults to br00k11n

NOTE: If you want to use different values for DB_USER and DB_PASS modify the creation-script-mariadb.sql too before running it.

Set Up Port Forwarding

sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
sudo iptables -t nat -I OUTPUT -p tcp -d 127.0.0.1 --dport 80 -j REDIRECT --to-ports 8080
sudo iptables -t nat -vnL

What's Next

1. Make DB configurable (use profiles to separate dependencies for each database type, currently we support H2 and MariaDB)
2. {Your Proposal here} (Please contribute!)
