Docker made creating a virtual container on any machine a snap and totally revolutionized the way we create, deploy and maintain our code. However, we rarely need to deploy a single container and running multiple connected containers takes time and so many things can go wrong in that process. We have various way to orchestrate containers in data centers using K8, DC/OS and Docker Swarm but what do you do as a developer on your laptop ? How can a developer simulate the data center in their laptops ? In this session we'll go over the basics of docker compose and will build together a mini containers cluster on a laptop.
