Docker Talk Ideas

On the 26th of September 2019 I will be giving a talk at PHP South Wales called 'Putting your Docker image on a diet'.

In this video I discuss a 10 minutes of the talk and answer the following questions: -  What is the difference between a Virtual Machine (VM) and a Docker container? -  What is the difference between Docker Images and Docker containers?
- What is a Docker image layer is and how it is create?
- What is a Dockerfile is and how does it creates a Docker Image
