Create Spring Boot Web project with Spring Tool Suite (in docker)
In this video we create a single /hw endpoint (short for helloworld) with Spring Boot using Spring Tool Suite.
We do it in docker to have reproducible results, and so that everything happens as if were the first time.
openjdk and firefox are installed in the image build script, which is shown for reference, but Spring Tool Suite is downloaded and initialized from scratch.
We also add the Spring Web dependency manually to show how to add additional dependencies.
This connect the docker container to the running server using volumes to bind to the host's X11 socket, and the user id is the same in the container and in the host (id 1000).
