Dockerfile

1. Pull the image from docker repository
2. Copy jar file into the image
3. 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.
4. Refer to Dockerfile.

docker build -t myorg/myapp .

To run the docker

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
