In this chapter we introduce a new way of running the Java Spring Boot microservice: Inside a Docker container. You will get to download the source code, compile the service and launch it inside an own virtualized server that runs inside your host machine. Docker is currently our choise of technology for launching the service. Docker is an architecture that can be utilized for running a new virtualized computer instances. This means that it has it's own memory and disk where the service will be installed in.
These instructions are tested only on a Windows host machine, they may apply also to Mac and Unix based systems. The commands running the container should apply to all environments.
You have to have the following setup installed on your host machine.
Oralce VirtualBox On Window machines. This is required to start a virtual machine.
You will also need the source code project from the end of the article to compile, run and install as a microservice inside the container.
