How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

jdx

// This script will boot app.js with the number of workers
// specified in WORKER_COUNT.
//
// The master will respond to SIGHUP, which will trigger
// restarting all the workers and reloading the app.

var cluster = require('cluster');
var workerCount = process.env.WORKER_COUNT || 2;

// Defines what each worker needs to run

cee-dub

package main

import (
	"fmt"
	"log"
	"net/http"
	"time"
)

// SSE writes Server-Sent Events to an HTTP client.

Terraform, CoreOS, and Digital Ocean

Let's use Terraform to easily get a CoreOS cluster up on Digital Ocean. In this example we will get a 5 node CoreOS cluster up and running on the Digital Ocean 8GB size.

Install Terraform

Grab a copy of Terraform for your platform from http://www.terraform.io/downloads.html. Follow the instructions at http://www.terraform.io/intro/getting-started/install.html by getting Terraform in your PATH and testing that it works.

Digital Ocean API Key

jfromaniello

This is a fork from the original CoreOS cloud formation template. It adds two EBS disks of 30G, mounted to /var/lib/docker.

This is intended to be used with an m3.large machine which comes with 30G of SSD.

The reason I add two of 30 and not one of 60 is because a BTRFS limitation.

You can use the "btrfs add" approach in the units to create a BTRFS raid.
