I’ve not had much experience with Docker – haven’t really seen the point until now. However, with his new tutorial, Alex Ellis makes a convincing argument. Docker is a way of packaging up software into an image, much like Raspbian is packaged. However, Docker images are installed on top of your operating system.

The tutorial helps you to get your Raspberry Pi and camera module streaming online to YouTube. Normally, there’s a lot of software set-up involved with this, but Alex has packaged it all up as a pre-built Docker image, saving you the bother. All the instructions are available on Alex’s blog.
