Everything You NEED to Know about Docker

We're diving into Docker - the basics and the whole ecosystem. We’ll go over you why developers use Docker, what it is and what it does, and how Docker fits into modern development - in various different ways - including a handful of newer Docker tools. At the end, you'll understand dockerfiles, images, and containers so you can use them in your own projects.

Let's start with why developers use Docker. Well, it’s because it containerizes your entire development environment. But what does that mean? Watch the video to find out!

It would be handy to cover volumes too, like if you update your Postgresql image, it doesnt remove all your data

So the cloud builder is faster on first build, yes. But also show another build with just a change in one of the source files. How is it comparing there?

1.15.10 wouldn't be the same number as 1.15.1 because it's a just a period separated value and not an actual number. Semver isn't meant to be read as a single number, nor is it really validly formatted as one, but rather major version 1, minor version 15, patch version 10.
