So you have written the uber-pro-web-application with a bazillion of active users. But your requests start to get out of hand and the Raspberry Pi under your desk can’t handle all the pressure on its own. Finally, the time for rapid expansion has come!
If you have already containerized your application, the step towards clustering your software isn’t that hard. In this post, we want to shed some light on management tools you can use to handle a cluster of Docker nodes.
Do you already have found time to recover from fighting the demons which made it hard to get a Docker cluster up and running on Raspberry Pis? Hopefully – because the next crusade lies ahead of us! So let’s dive into the next adventure, watching our heroes – three greenhorn students – on their search for their Intel NUC’s missing boot target.
Raspberry Pis are small, cheap and easy to come by. But what if you want to use Docker on them? Our goal was to run Docker on several Raspberry Pis and combine them to a cluster with Docker Swarm. To achieve this, we first needed to get Docker running on the Pi.
