Please edit this content section.

Course Description:

This course in intended for absolute beginners. It is recommended for anyone who wants to start working with Docker and it is addressed to sysadmins and developers. It will give you hands-on experience creating and managing lightweight, easily-deployable containers for your software development projects.

This course will start with an overview of Docker architecture and will proceed with installing Docker. The students will get familiarized with Docker commands and will be able to create and manage containers and images. The course will also cover networking concepts, data persistence in the context of containers and Docker scaling and container orchestration using Docker Swarm.

All these features will be explained and demonstrated with hands on examples in the practice lab.

Note: Every student has assigned to him his own virtual lab environment setup.

What will you learn:

After completing this course, students will have a firm understanding of many core Docker technologies and key features including the Docker Hub, Docker Compose, Docker Swarm, Dockerfile, Docker Containers, Docker Engine, Docker Images, Docker Network, Docker Daemon and Docker Storage.

The course doesn't have any prerequisites however, an understanding of general OS structure and internals will help you understand how containers work. Also, familiarity with the Linux command-line will help when interacting with Docker containers.
