Learn the ins and outs of containerization in Docker with this practical guide! Begin by installing and setting up the platform. Then master the basics: get to know important terminology, understand how to run containers, and set up port redirecting and communication. You'll learn to create custom images, work with commands, and use key containerization tools. Gain essential skills by following exercises that cover common tasks from packaging new applications and modernizing existing applications to handling security and operations.

1) Installation and configuration
2) Dockerfiles
3) Docker commands
4) Rootless Docker
5) Project migration
6) GitLab
7) Grafana
8) Kubernetes
9) Container security
10) Continuous integration and delivery (CI/CD)
11) Docker images: servers, databases, programming languages, and web applications
