Well, container sit in the middle of those two extremes! They allow you the chroot to be “in your own little world” but also can make up a virtual network and simple stuff like that, but they are not full blown virtual machines. It’s limiting which parts of the file system can be seen from within the chroot, that’s it. The other extreme is a tiny “chroot” in Linux, that allows you to separate whatever is running in the chroot a little bit from the rest of the Linux world it exists in.

But hopefully it will help you get started.Īs others have pointed out, containers are all about making installation and packaging of software or services easier - get everything into a neat package that works and it will guarantee it’ll very likely just run wherever you take it.Īnother important concept here: you know how VMware can magically create a whole virtual PC with virtual hardware? That’s the one extreme, now you need to install a whole OS in there. Wouldn't it be great if I could just rent space in the cloud, and there was a way I could configure how many containers to spin up, depnding on the traffic load, congestion, my needs at the time, etc? Hmm, my business is growing and I am spending all my time installing and managing containers.
Boo.īut what if there was a way to just run everything exactly the same as my first setup, as many times as I want, without having to go through all the steps again? And what if it would work on any hardware without having to change the settings? Now I have to set up everything exactly the same way again. Oh no, there are too many people using my server, and I need a second one. I spend hours installing all my software, configuring everything, setting it all up the way it needs to work properly.
