Dockerfile

Copy jar file into the image
exec form of the Dockerfile ENTRYPOINT is used so that there is no shell wrapping the java process. The advantage is that the JAVA process respond to the KILL signal sent to the container.
Refer to Dockerfile.

Docker command

To build an image:

docker build -t myorg/myapp .

To run the docker

docker run --name myapp -it --enrtrypoint myorg/myapp

To interact with the docker

docker exec -it myapp /bash

Summary

REST is not about just pretty URIs and return JSON instead of XML.
Don't remove old fields. instead, support them.
rel-based (HATEAOS) - did not implement
Retain old links as long as possible
use links, not payload data, to instruct clients when various state-driving operation are available
