A friend of mine pointed me to a twitter thread on how to explain Kubernetes to a five year old. Since I have a two year old, this immediately popped into my head.
I’ve seen the Lonely Goatherd scene from The Sound of Music many a time – my daughter absolutely loves it. And it seems to be a fairly good explanation for Kubernetes. Hear me out:
Stage = Kubernetes Cluster
The stage is the Kubernetes cluster where the application is deployed. This includes the Nodes, environment, config maps, secrets, etc.
Puppets = Containers/Pods/Microservices
The puppets are the actual microservices made up of Pods and Containers.
Julie Andrews = DevOps
Julie Andrews (Maria) is the poor DevOps soul who is staving off disaster with kubectl, helm charts, APIs, etc.
Kids = Kubernetes Scheduler
The Kids are (mostly) doing what Julie (DevOps) is telling them to do. They are adding and removing the puppets (containers) as she has directed.
Audience = End Users
The Audience is the end users of the application… but let’s not kid ourselves – this app is not in production, so the audience is really QA. 🙂
