#!/usr/bin/env python3
#
# Script to replace EC2 instances in an ECS cluster's auto-scaling group after
# changing the AMI or instance type in the launch configuration. It 
# checks for instances with the incorrect AMI or type, scales up the
# auto-scaling group with replacement instances, then drains the tasks
# from the old instances.
#
# Usage: aws-vault exec profile-name -- python3 replace_ecs_cluster_instances.py --group=asg-name --cluster=ecs-cluster-name --count=3

Introduction

Sometimes you may want to use a DNS server for specific domain requests and another DNS server for all other requests. This is helpful, for instance, when connected to a VPN. For hosts behind that VPN you want to use the VPN's DNS server but all other hosts you want to use Google's public DNS. This is called "DNS splitting."

Here, we run dnsmasq as a background service on macOS. The dnsmasq configuration described below implements DNS splitting.

Install

brew install dnsmasq

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
