I just had to set up Jenkins to use GitHub. My notes (to myself, mostly):
For setting up Jenkins to build GitHub projects. This assumes some ability to manage Jenkins, use the command line, set up a utility LDAP account, etc. Please share or improve this Gist as needed.

| # One way to use this is by placing it into a file called "cors_support" | |

| 'Twas the night before Christmas, when all through the racks | |
| Not a server was alerting, not even Compaqs. | |
| The backups were written to tapes with care | |
| In hopes that later the data would be there. | |
| The machines were nestled all snug in their sleds | |
| Whilst visions of vengeance danced in their heads; | |
| And oncall in his three-wolf and I in my rack. | |
| Had just settled down for some syn and some ack. |
| - What do Etcd, Consul, and Zookeeper do? | |
| - Service Registration: | |
| - Host, port number, and sometimes authentication credentials, protocols, versions | |
| numbers, and/or environment details. | |
| - Service Discovery: | |
| - Ability for client application to query the central registry to learn of service location. | |
| - Consistent and durable general-purpose K/V store across distributed system. | |
| - Some solutions support this better than others. | |
| - Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state. | |
| - Centralized locking can be based on this K/V store. |
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.
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.

Sorry, I have to disagree with the entire premise here.
A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.
Mastery comes from a combination of at least several of the following:
There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.
All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.
What do these lines do? Make predictions and then scroll down.

| If you prefer to make a bootable dvd, you can do it this way: | |
| After downloading the full Yosemite installer app from the Mac App Store, run these 14 commands in Terminal to create a Yosemite.iso file and then burn it to a dual layer DVD with Disk Utility. You may then boot up from it by holding the option key down and then install Yosemite. | |
