If you’ve followed my previous Docker videos, you know you have to prefix each docker command by sudo--unless of course if you are directly running your shell as root. Pfff! It’s so boooring to type those five extra characters before each command…​

In a previous video, we’ve installed the Oracle Database in a Docker container. Today, we will see how we can run SQL Developer, an X11 graphical application directly from that container.

Despite great opensource alternatives, Oracle Database skills remain in high-demand on the job market. But installing Oracle from scratch is a tedious task. Fortunately, Docker is here. The Oracle license allows you to install and run an Oracle instance for education or testing purposes. And you can find on the official Oracle website, both the installation media and some pre-installed virtual machines images freely available. Both those solutions have drawbacks, especially when you are new to Oracle and don’t have access to an overpowerful computer.

Installing and running a web server in just a few seconds. Just a dream? No—​and in fact it is pretty easy to achieve using Docker containers! Even better, once you know how to do it, you could run many other kinds of servers exactly the same way…​ Containers are a great way to start services with a minimum overhead and little to no configuration issues. This has tremendous advantages in production. But for development and educative purposes, this is also a great tool.

In this video, I show you how to install the latest version of Docker on Debian/Ubuntu/CentOS, straight from the project repository — and that, in a secure manner by checking first the remote repository key fingerprint!
