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.

Others have recently developed packages for this same functionality, and done it better than anything I could do. Use the packages instead of this script:

Description

In its basic usage, this script will modify the router such that blocked addresses are null routed and unreachable. Since the address blocklist is full of advertising, malware, and tracking servers, this setup is generally a good thing. In addition, the router will update the blocklist weekly. However, the blocking is leaky, so do not expect everything to be blocked.

Overview

I'm tired of massive delay (500-1000 ms pings) while uploading large files. QoS helps some, but a significant portion remains due to bufferbloat (100-150ms). This leads to delay in VoIP calls and generally sluggish web browsing while uploading.

The new Codel algorithm in OpenWRT / Attitude Adjustment should help a lot. The results below show only ~5-6ms of added latency during uploads (i.e. 14ms vs 500+ms before!). Insane.

These instructions are for the TP-Link TL-WDR4300, because I got a good deal. If you have the money, buy a Netgear WNDR3800 and install CeroWRT, you'll probably see even better results.

Why the TP-Link TL-WDR4300

In short, its fully supported in OpenWRT Attitude Adjustment and works well for my needs:
