HOWTO: Installing Vault On AWS Linux

This is quick howto for installing vault on AWS Linux, mostly to remind myself. At the end of this tutorial, you'll have a working vault server, using s3 for the backend, self signed certificates for tls, and supervisord to ensure that the vault server is always running, and starts on reboot.

Setting up S3

First things first, let's set up an s3 bucket to use as the storage backend for our s3 instance.

From the AWS Mangement Console, go to the S3 console.
Click on the Create Bucket button

3 x Cluster on AWS

manager1
worker1
worker2

Docker-machine commands

Use docker-machine to lay down 3 x hosts on AWS using docker-engine 1.12

docker-machine create --driver amazonec2  --amazonec2-private-address-only --engine-install-url https://test.docker.com/ levenson-docker-swarm-manager1 
docker-machine create --driver amazonec2  --amazonec2-private-address-only --engine-install-url https://test.docker.com/ levenson-docker-swarm-worker1

DevOps started out as "Agile Systems Administration". In 2008, Andrew Shafer did a talk called "Agile Infrastucture" addressing issues around involving more of the company in the same disciplines as programmers.

In 2009, Patrick Debois created "DevOpsDays" conference to help to bring it to light. However, it wouldn't begin to trend until about 2010, when people would begin to describe it as a standalone discipline.

Today, DevOps goes beyond just developers, systems administration and infrastructure, its about [dev, ops, agile, cloud, open source and business](https://blogs.the451group.com/opensource/2010/03/03/devops-mixing-dev-ops-agile-cloud-open-source-and-busi
