Clone source code from git
$  git clone https://github.com/dstar55/docker-hello-world-spring-boot .

Run Docker Container
$ docker run -p 8080:8080 -it --rm hello-world-java
Test application
$ curl localhost:8080

the respone should be:

Hello World
Stop Docker Container:
docker stop `docker container ls | grep "hello-world-java:*" | awk '{ print $1 }'`

Run with docker-compose

Build and start the container by running

$ docker-compose up -d 
Test application with command
$ curl localhost:8080

the respone should be:

Hello World
