Rancher: Running custom Express application

Introduction In this post, we set up a Rancher cluster and in this one we installed a default WordPress application on it. Though this was a very simple example, it gave us a good view on how to work with Rancher. In this post, we are continuing from where we left of and we’ll install a customer application… Read More »

Rancher: Getting started

Introduction Containers are causing a real revolution. Docker is great (although I’m starting to see some decay as well) but Docker is not always as straightforward as you might think. It’s hard to manage millions of Docker containers, it’s hard to setup networking properly, …. Since release 1.12, there are some improvements though. In any case, I already… Read More »

We will create two hosts and will run a container on each of them and try to connect the two containers without having a common overlay network. Then we will create an overlay network and repeat the same exercise again. Setting up multi-host environment To… Read More »
