This gist is mostly based on the dnsmasq appendix from the openshift-training repo. However, I updated it and included fixes for the many gotchas I found along the way.

This is useful for folks who want to set up a DNS service as part of the cluster itself, either because they cannot easily change their DNS setup outside of the cluster, or just because they want to keep the cluster setup self-contained.

Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

XCode is installed (via the App Store)
XCode command line tools are installed (xcode-select --install will prompt up a dialog)
Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

	#!/bin/bash
	set -e
	set -o pipefail

	# Add user to k8s using service account, no RBAC (must create RBAC after this script)
	if [[ -z "$1" ]] \|\| [[ -z "$2" ]]; then
	echo "usage: $0 <service_account_name> <namespace>"
	exit 1
	fi

	'use strict';

	// You use the `ResourceVersion` when making the initial query. So keep track
	// of that upon successful reads and when you need to recreate the watcher from
	// the last known point, pass in the `ResourceVersion` in the query.

	const fs = require('fs')
	const http = require('http')

	const K8S_HOST = process.env['K8S_HOST'] \|\| '10.100.0.1'

	#!/bin/bash

	# requires https://stedolan.github.io/jq/download/

	# config
	KEYCLOAK_URL=http://localhost:8080/auth
	KEYCLOAK_REALM=realm
	KEYCLOAK_CLIENT_ID=clientId
	KEYCLOAK_CLIENT_SECRET=clientSecret
	USER_ID=userId

	FROM golang:1.6.2

	COPY . /go

	RUN go get github.com/nats-io/nats
	RUN go build api-server.go

	EXPOSE 8080
	ENTRYPOINT ["/go/api-server"]

	package main

	import (
	"log"
	"bufio"
	"time"
	"os"
	"fmt"
	"io"
	"net"

	# taken from http://www.piware.de/2011/01/creating-an-https-server-in-python/
	# generate server.xml with the following command:
	# openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes
	# run as follows:
	# python simple-https-server.py
	# then in your browser, visit:
