Manually Edit AWS Console "Switch Role" Configuration in Bash

Motivation

At Gruntwork, we work with multiple software teams. That means we have to modify the "Switch Role" history multiple times. But the only way to do that today is to delete your cookie and clear all AWS Console saved settings. That got old after a while, so these instructions enable you to modify the "Switch Roles" configuration directly.

The Big Picture

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2025-03-24: Commenting is disabled permanently. Previous comments are archived at web.archive.org. ]

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

Source Code Typography

Presentation: http://www.slideshare.net/vancura/source-code-typography

Quotes

Dumb quotes (also known as straight quotes) are straight and vertical. Proper typography never uses straight quotes. They are left over from the age of typewriters, and their only modern use is for coding.

ChefDK, Test Kitchen Driven NTP Cookbook via Docker

This gist is a fork from lamont-granquist modified to be even easier and faster by taking advantage of Docker. Given the rapid development and change rate of Chef finding this gist with instructions that still are valid and reasonable was much appreciated.

This gist uses TK+Berkshelf to drive creating a vagrant virts and converging a simple recipe to install and configure NTPd. This is a simple cookbook that has one recipe, one template (for ntp.conf) and one attribute file. It works on Ubuntu 12.04/14.04 and CentOS 6.4/7.1 (and derviatives) and the attribute file is used to support both distros.

This should work on Mac (where I developed it) and any chef-supported Linux that you can get Docker onto (Ubuntu/CentOS).

Because I use ChefDK and Test Kitchen, I can largely ignore setting up Docker and Berkshelf and can get right to work on writing recipe code.
