In this chapter, we will start using Docker and put our microservices into containers!
By the end of this chapter, we will have run fully automated tests of our microservice landscape that start all our microservices as Docker containers, requiring no other infrastructure than a Docker engine. We will have also run a number of tests to verify that the microservices work together as expected and finally shut down all the microservices, leaving no traces of the tests we executed.
Being able to test a number of cooperating microservices in this way is very useful. As developers, we can verify that it works on our local developer machines. We can also run exactly the same tests in a build server to automatically verify that changes to the source code won't break the tests at a system level. Additionally, we don't need to...
