CoreOS Cluster on Many Macs using Xhyve

As a holiday project, I thought I'd try my hand at using xhyve on OSX instead of the more established Vagrant CoreOS Cluster set up as it has less overhead.

Xhyve is a port of the BSD package bhyve virtualization platform that is the default for FreeBSD 10 and up. There's a great section in the BSD about bhyve here: https://www.freebsd.org/doc/handbook/virtualization-host-bhyve.html

A couple problems arose, mostly because I was unfamiliar with the xhyve and its use of TAP adapters on OSX, but regardless, I think the expirement was a great learning process and wanted to share with others.

Note: you'll need OSX Mavericks (10.10.x) or El Capitan (10.11.x) or later in order to use xhyve. In order to asses the version you are currently running:

	#!/bin/bash
	cat >> /etc/elasticsearch/elasticsearch.yml << EOF
	cluster.name: ELASTICAWESOME
	cloud.aws.access_key: ACCESS_KEY_HERE
	cloud.aws.secret_key: SECRET_KEY_HERE
	cloud.aws.region: us-east-1
	discovery.type: ec2
	discovery.ec2.tag.Name: "ELKBEE"

	http.cors.allow-origin: "*"

	#! /bin/bash
	ssh -C -D 1080 hostname -o 'GatewayPorts yes' -q

	#essentially:
	#-C - compression
	#-D - tunnel and port (use 127.0.0.1 as Socks and 1080 in FF)
	#-o - option, this one stops the annoying "Channel 9 dropped" errors
	#-q - quiet, to get rid of any other errors

	#! /bin/bash
	echo "127.0.0.1 localhost" \| sudo tee --append /etc/hosts
	echo "127.0.0.1" `ec2metadata --local-hostname` \| sudo tee --append /etc/hosts

	## Remove --append to overwrite the file

	#!/bin/bash
	docker rm $(docker ps -a \| sed '1d' \| awk '{print $1}')

	#!/bin/bash
	docker rmi -f $(docker images \| sed '1d' \| awk '{print $3}')
