One way to make containers network: BGP

Linux containers are really cool these days. I hear people talking about Docker and Kubernetes and Rocket and all these things all the time. And if you have containers, you have to network them together!
A lot of computer topics are explained in an unnecessarily confusing way, but I think networking can be especially hard for developers to read about — I’m reading a page right now that talks about virtual networking layers, overlay networks, payload encapsulation, BGP, control planes, packet fragmentation, TAP, veth, Neutron, data center fabric, anycast, vRouters, tunneling, VRF tables, VXLANs… ugh.
A lot of this stuff is not that hard though! I know that packets have IP addresses and ports on them and it turns out that takes you a pretty long way. So let’s talk about a way that containers could talk to each other.
I’m not going to talk too much about what a container is in

How (And Why) FreeDOS Keeps DOS Alive

FreeDOS was originally created in response to Microsoft’s announcement that after Windows 95, DOS would no longer be developed as a standalone operating system, according to a new interview about how (and why) Jim Hall keeps FreeDOS alive. For its newest version, Hall originally imagined “what ‘DOS’ would be like in 2015 or 2016 if Microsoft hadn’t stopped working on MS-DOS in favor of Windows” — before he decided there’s just no such thing as “modern DOS”. An anonymous Slashdot reader writes:

No major changes are planned in the next version. “The next version of FreeDOS won’t be multitasking, it won’t be 32-bit, it won’t run on ARM,” Hall said. “FreeDOS is still intended for Intel and Intel-compatible computers. You should still be able to run FreeDOS on your old 486 or old Pentium PC to play classic DOS games, run legacy business programs, and support embedded development.”

By day, Hall is

Kubernetes the Hard Way

README.md

This tutorial will walk you through setting up Kubernetes the hard way. This guide is not for people looking for a fully automated command to bring up a Kubernetes cluster. If that’s you then check out Google Container Engine, or the Getting Started Guides.

This tutorial is optimized for learning, which means taking the long route to help people understand each task required to bootstrap a Kubernetes cluster.

Target Audience

The target audience for this tutorial is someone planning to support a production Kubernetes cluster and wants to understand how everything fits together. After completing this tutorial I encourage you to automate away the manual steps presented in this guide.

Cluster Details

Kubernetes 1.3.0
Docker 1.11.2
CNI Based Networking
Secure communication between all components (etcd, control plane, workers)
Default Service Account and Secrets
What’s Missing

The resulting cluster will be missing the following items:

Labs

The following labs assume you have a working Google Cloud Platform account and
