How to Install Docker on Debian/Ubuntu/CentOS ? Yes, I Know IT ! Ep 15
📂 Go to https://yesik.it/EP15 to download the files used in this video, so you can practice on your own system.
Docker is a popular container technology allowing you to run services and processes in isolation. I started recently to use docker more and more for testing and education purposes. It's definitely a lightweight alternative to full-fledged virtual machines since I can spawn an Ubuntu or CentOS environment on my Debian system in a matter of seconds.
But since the Docker project is evolving rapidly, that means, unless you are using a rolling distribution, the Docker version available in your system repository is probably outdated. Way outdated...
In this video, I explicitly show you how to install the latest version of Docker on Debian/Ubuntu/CentOS, straight from the project repository. But the instructions for Debian/Ubuntu should work in most APT-based distributions (including all Ubuntu derivatives). And the CentOS instructions should work without any issue on RHEL, Fedora, and other RPM-based distributions.
As a final notice, pay special attention to the remote repository key verification part. This is really an important step of the process to ensure you are installing a genuine software on your system. In fact, even if you do not plan to install Docker, you should watch the video at least for that part: too many installation tutorials out there simply ignore that -- whereas blindly installing a new trust anchor on your system is a major security flaw!
