Scaling Docker #3 - Docker Service Registration with Etcd & Flannel

2 of the biggest problems to solve with Docker infrastructure are service registration & service discovery. In this video, we’ll cover the more complicated piece, which is service registration. Every Docker container needs to register itself as a web service that can be consumed or load balanced by other containers. VIDEO 1: - Cluster computing - CoreOS is our solution here. CoreOS allows us to make an expandable cluster of computers so we can add more computers should our application need more power to scale. CoreOS also allows us to run services on any machine in the cluster and they can all communicate with each other. VIDEO 2: - Scheduling: we shouldn’t manually choose which app runs on which machine - this idea doesn’t work at scale. Fleet will be our scheduler that decides where our apps/services run. If a CoreOS machine goes down, fleet will reschedule any services that it was running onto a new machine. THIS VIDEO:
