Containerize a Dropwizard application with Jib

How to start the Dropwizard application

1. Run ./mvnw clean package to build your container
2. Start the application
   • With Docker: docker run --rm -p 8080:8080 dropwizard-jib-example:1
   • Without Docker: ./mvnw exec:java
3. Check that your application is running at http://localhost:8080

Health Check

See your application's health at http://localhost:8080/admin/healthcheck

Extras

FreeMaker templating is setup for dropwizard.yml through tkrille/dropwizard-template-config; this allows one to heavily customize the properties file via the container environment with FTL conditional checks and for loops, for example.
