This document provides an agenda for a hands-on Docker training. It includes sections on the Docker engine, containers and images, image registries and Docker Hub, container isolation, and preparing a Docker environment. Key points covered are running the first Docker container with "hello-world", pulling and running the Alpine image, using Docker commands like "run", "ps", "stop", "start", and "exec", and signing up for a Docker Hub account to push and pull images from a registry. The final section instructs setting up a VMware Workstation with CentOS7 to create a first Docker environment.

- 5. Docker engine • Running your first container => Run docker run hello-world
- 8. Containers & images • Docker Images • Run => • The pull command fetches the alpine image from the Docker registry and saves it in our system. In this case the registry is Docker Hub • You can change the registry, but that’s a different lab docker pull alpine Alpine is a lightweight Linux distribution so it is quick to pull down and run, making it a popular starting point for many other images
