Docker Swarm Mode with visualizer

Introduction Recently I came across this project. Looked quite cool and it’s something I have been looking for quite a while.

Introduction This post is inspired by this DigitalOcean post but instead works using a Vagrant file that I will provide below. Configuration of the system We will install a Mesos cluster and will be assuming the following configuration. Installing Mesos Masters As mentioned above, we will be using Vagrant to install our Mesos cluster. In order to do… Read More »

Docker: multi-host networking (using overlay)

Introduction In this post, we will experiment a little bit with multi-host networking. 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 »
