Hands-on Docker Course

The Docker course is designed to offer aspiring DevOps engineers the broadest and deepest understanding of how to work with Docker.

At the start of the course you'll learn how to install Docker, as well as the basics of working with containers, images, and so on; you'll gain knowledge of the Dockerfile and be able to build images using the Docker file system.

Next, the course will cover the specifics of storing data in Docker using volumes. We'll look at the mechanism for persistent storage of data created and used by Docker containers. In addition, DevOps engineers will study working with environment variables and their use in Docker.

Advanced sections include training on multistage builds and using the Docker Registry. You'll also learn how to configure networks in Docker and use various tools for working with Docker, including logs, inspect, lazydocker, and so on.

Special attention will be paid to Docker Compose and security in Docker. Finally, the course will conclude with training on Docker Swarm, which will give you the ability to manage a Docker cluster and ensure high availability and scalability of your applications.

This course will allow you to become competent and confident in working with Docker, mastering all of its key features and capabilities.

Who is this course for?

For DevOps engineers, developers and system administrators who want to learn modern approaches to containerizing and managing applications.

How does automatic validation of a task work?

A dedicated algorithm checks that Docker images are built correctly, that containers start properly and that the result meets the task requirements

What baseline knowledge do I need to complete the tasks?

You will need basic knowledge of the Linux command line and an understanding of how web applications work

How long is this course expected to take?

The estimated time to complete this course is 15-25 hours. There are no fixed schedules; you learn at your own pace and always continue from where you left off.

If I can't find an answer to my question, will you help?

We will! If something is unclear at any step, just ask. If some information is missing altogether, ask as well. We may add a new section.

Can I skip some tasks and jump straight to an arbitrary one?

Yes, you can. However, keep in mind that some tasks depend on one or more previous ones. In that case, you need to complete those first.

How is this different from similar courses on well-known educational platforms?

To begin with, this is not a classic course but a hands-on practicum. Theory is given in the context of tasks. Employers today don't particularly value graduates of well-known courses; what they need first and foremost is experience. And experience can only be gained through real work.
