How to Setup Kubernetes on DigitalOcean with CoreOS

Kubernetes on DigitalOcean with CoreOS

Let's look at an example of how to launch a Kubernetes cluster from scratch on DigitalOcean, including kubeadm, an Nginx Ingress controller, and Letsencrypt certificates.

Overview

Environment

We'll be creating a four-node cluster (k8s-master, k8s-000...k8s-002), load balancer, and ssl certificates.

Lightning Fast WordPress: Caddy+Varnish+PHP-FPM

README

This gist assumes you are migrating an existing site for www.example.com — ideally WordPress — to a new server — ideally Ubuntu Server 16.04 LTS — and wish to enable HTTP/2 (backwards compatibile with HTTP/1.1) with always-on HTTPS, caching, compression, and more. Although these instructions are geared towards WordPress, they should be trivially extensible to other PHP frameworks, other FastCGI backends, and even non-FastCGI backends (using proxy in lieu of fastcgi in the terminal Caddyfile stanza).

Quickstart: Use your own naked and canonical domain names instead of example.com and www.example.com and customize the Caddyfile and VCL provided in this gist to your preferences!

These instructions target Varnish Cache 4.1, PHP-FPM 7.0, and Caddy 0.10. (I'm using MariaDB 10.1 as well, but that's not relevant to this guide.)

Promise protips - stuff I wish I had known when I started with Promises
// Promise.all is good for executing many promises at once
Promise.all([

// Promise.resolve is good for wrapping synchronous code
Promise.resolve().then(function () {
