Download Docker For Ubuntu 20.04
Hello everyone, I hope you are all having a great week so far with that said you can finally download Docker for Ubuntu but before you do that, my day has been crazy to say the least, we had a massive power outage here yesterday, we had no lights in the whole town, it was annoying to say the least. Today, the lights are back but the stupid energy company that supplies lights here apparently hasn’t fully fixed the problem. At this rate I really might have to move permanently to another country, I have a few in mind, lol anyway, please read on…
Today we will highlight one of the best and most useful apps for Ubuntu and Linux administrators. I am talking about Docker. Heard of it? Probably but at the time you probably had no idea what it is or why you see it pop up on some web sites here and there. Okay, maybe that is just my experience but while at work, a co-worker recommended upgrade our network and he recommended Docker. I was like, wtf is Docker? Let’s find out.
What Is Docker?
Docker is an app that makes it simple and easy to run application processes in a container, which are like virtual machines, only more portable, more lightweight which means they are naturally resource friendly, and more dependent on the host operating system. Docker provides an open platform for developers and sysadmins to build, package, and run applications anywhere as a lightweight Docker container. Docker automates the deployment of applications inside software containers.
