Full Docker Course for Beginners (~3 Hours, Free)

Hi there **👋**

I created a [**complete Docker course**](https://youtu.be/3c-iBn73dDE), which I think could be interesting for some (beginners) of you. If you're just getting started with Docker, but maybe also good for refreshing some concepts.

By the end, you will have a deep understanding of the concepts and a **great overall big picture of how Docker is used in the whole software development process**.

The course is a **mix of animated theoretic explanations** and **hands-on demo’s** to follow along, so you get your first hands-on experience with Docker and feel more confident using it in your projects.

Demo project: JS/NodeJS/MongoDB/MongoExpress
