Kubernetes troubleshooting
If things aren't going to plan, this video describes how to get logs of the events in Kubernetes to work out why containers might not be initializing properly. Also, if the containers are working, but the microservices are not working, I describe how to view the spring boot logs in the running pods.
Hopefully, if you are trying to follow along with the playlist, but are having problems, this video will help you to debug things.
