PodLogsWatcher

This project shows how you can tail all the PODs logs you want leveraging the API offered by fabric8io/kubernetes-client;

Basically it showcases you can do in Java the same thin stern achieves using GO;

To see it in action, download minikube and run:

minikube start
mvn test

This command starts test PodLogsTestCase and this is what happens:

• the test has the custom annotation @PodLog
• the custom annotation @PodLog has the JUnit 5 annotation @ExtendWith(PodLogExtension.class): this annotation tells JUnit to register the PodLogExtension custom extension
• the PodLogExtension custom extension starts watchLog for every newly running POD

Loggable#watchLog is an API offered by fabric8io/kubernetes-client which tails a POD's log and redirects it to an OutputStream;
