Bookshop project using Spring Boot 2.1 and JUnit 5 compiling with Java 11

In this demo project I will be using Spring Boot 2.1 and jUnit 5 in their latest releases.

Accessing to the H2 database

You can access to the database typing http://localhost:2289/console and using as JDBC URL this one: jdbc:h2:mem:bookshop and the user name is sa and the password is password.

Postman Collection

I have provided a Postman collection with all the existing endpoints and examples of calls for each one of them.

Docker

Running the Bookshop app as a single instance within a container on port 2289

If you want to build an image for docker, just execute the command docker build -t dockerbookshop . to build the image and then use docker run -p 2289:2289 docker-bookshop to run it within a docker container.

Running 10 instances behind a load balancer on port 80

First of all, you need to run the command docker swarm init to create a Swarm within docker and then run docker stack deploy --compose-file=docker-compose.yml bookshop-stack. You will see how the 10 instances start to spin up and eventually all of them will be working. Each one will have it own H2 Database so the database is not distributed. To leave the Swarm and stop and delete all created containers run the command docker swarm leave or docker swarm leave --force in case the first doesn't work.
