Definitely. I'm glad they're testing us on this stuff - it's crucial for anyone working with containers and Kubernetes. I'm ready to dive in and see what we can find. Anyone else want to take a crack at it?

Haha, 'juicy issues' - I like that! But you're absolutely right, we need to be really thorough in reviewing both the Dockerfile and the deployment YAML. Security and best practices are so important, especially for a certification exam.

Good point about the base image. That's definitely a security concern, especially for a production deployment. And let's not forget about the deployment YAML file. I bet there are some juicy issues there too, like hardcoded credentials or exposing sensitive information.

I agree, the Dockerfile is a good place to start. Maybe we're running processes as root or installing unnecessary packages. Oh, and we should definitely be using a more recent base image than Ubuntu 16.04.

Alright, let's get started. First, I'll take a look at the Dockerfile. Hmm, I wonder what those prominent security/best-practice issues could be. I bet it has something to do with the base image or the packages we're installing.
