Installing programs is something most people take for granted. How could it be easier – you simply download an installation file, run it, answer a few prompts, and before you know it you have a fresh new application ready to go. This is fine for a single-user system like a laptop or desktop, but what happens when you want to share that program with someone else, or migrate it – along with its configuration and settings – to a different computer? What if you wanted to do a clean reinstall without having to hunt for scattered or leftover files?

Docker provides a unique way of accomplishing this, and the technology behind it is quickly gaining traction. Continue reading “Contain Your Excitement: Building Portable Apps with Docker”

If you’ve been following the previous steps of this guide, you should have a secure, freshly updated installation of Ubuntu Server which you can access from another computer on the network using SSH. If that’s the case, you can safely unplug the keyboard and monitor from your server – you won’t be needing them. If you’re running your server behind a router (e.g., on a home network), chances are your server won’t be accessible from the outside world. This section explains how to make your server available to the public Internet so you can access it from home or while on the go.

At this point, you should be able to access your server through your local network. You won’t be able to access it from the Internet, but don’t worry about that just yet. There are a couple of important security steps before your server goes public that we’ll get to later. In the meantime, let’s focus on the real reason you’re here: hosting your own file sync and music streaming services locally.

Now that you know how to use your shiny new Linux server, it’s time to make it accessible over the network.
