GLaCOS (Genetic Lifeform and Cloud Operating System), your AI research assistant, had nothing to do lately, so you decided to create a little game for him to keep him entertained. You downloaded the cloud GLaCOS operates and stored it under the /root/devops/cloud directory. Here are the rules of the game you came up with.

There are a bunch of folders and files under the root/devops/cloud directory. The are two types of files in the system:

A hint. Each hint file starts with a line containing a single "Hint" word (without quotes or leading/trailing whitespace characters). The second line contains a sequence (possibly empty) of words "up" and "down", separated by a single whitespace character. Not a hint. It is guaranteed that the first line of the such a file is not "Hint". The goal of the game is to find a secret folder. It is known that there is a sequence of hints that leads to it, and that the first hint is called start.hint and is located in root/devops/cloud. Here's how to win the game starting with th

Easy Kubernetes Installation on CoreOS

At Timeline Labs, we are continuously looking at new technologies to see what fits our needs. We are especially excited about Kubernetes from Google to manage our services atop Docker and CoreOS.

This process for installing Kubernetes on CoreOS uses Flannel for Kubernetes networking and should be cloud provider agnostic. To deploy the Kubernetes master functionality into the cluster, it uses fleetctl.

Thanks to Kelsey Hightower and his blog posts! They served as a great starting point for this process.

How do I get this running?

Add the cloud config below to your own and bring up your cluster using a CoreOS version with Docker 1.3 (currently v472.0.0 in alpha). During that initial boot, the download-kubernetes and download-flannel units will download binaries from the latest project release and use those.
