Docker Notes
---
docker daemon 
REST Api to interact with it
CLI to interact with it uses the REST APIs

your docker daemon can run on a totally different machine and you can issue commands to it from your local

'dockerd' = daemon
'docker' = using the api

Docker Orchestration
----

Kubernetes
---
Takes declared state, and works to make that happen across a cluster.

Node - 'kubelet' runs pods and talks 2 master. Node = Computer
Pod - runs 1+ containers, exists on node
Service - handles requests using LB

NodeJS
---
Every file is a 'module'
console.log(`Hi ${this.name}!`); <-- `` Templating
Make sure to use the relative path when importing or node will think you are using the built in module


exports.sayHello = function() {
  console.log("Hello!");
};
