A Quick Look
Setting Up an Ubuntu 20.04 Docker Container
Because you might need it
Have you needed a quick Linux instance? You’ve wanted to test something out without having to create a dual boot or all the none-sense of a separate Operating System?
Think about this scenario:
You’ve just finished your new project: a NodeJS API Server. It’s wonderful; the best of the best. It spits out random tweets from users and makes a PNG of them. You think it’s awesome but before you release it to the world you want to test that it’s going to work for every instance you run it on; every different version of NodeJS and on Linux/Windows/macOS too. This will also ensure you can put it up on a server of your choice later on (preferably the cheapest). Maybe even a Serverless function?
That’s where Docker comes in.
Docker is a containerization tool used by developers to set up virtual environments running whatever you need to get your application running on an external host. This is the ability to containerize and ship your application without being tied to a specific host.
