Kubernetes On Windows

Early in August 2016 Microsoft released the Windows 10 Anniversary Update. There were a number of changes, but the one that got me to actually take the time to install the update was "Bash on Ubuntu on Windows". This feature would install Ubuntu Linux without the kernel. It would run linux in user-mode. Linux would run the commands while Windows does all the work/processing.

For an upcoming project I needed to get Kubernetes running. Being as Kubernetes is not able to be run in Windows the normally accepted way to procees is to create a virtual Linux box and run it from there. I wanted to see if Kubernetes would run in Bash on Ubuntu on Windows.

This is how I got it to work:

Task queuing in Django with ZeroMQ

Introduction

Here at Glitterbug Tech, Django is the lifeline of everything we make and we are big fans! Django doesn't get in the way and lets us write the language we love, python, while providing an amazing set of tools that makes creating web applications fast and fun. But, as you know, code is executed synchronously before you can send back a response. Which means when you are generating that report from your database which has a million rows, your client has to wait for a response while your application huffs and puffs trying to get everything ready (Unless he times out, in which case you receive angry calls while you try to explain what "502 Bad Gateway" means). Sometimes you just want to make your site more responsive by pushing time consuming tasks in the background ("Your comment has been posted!" while a zmq process works in the backend adding it to your db/caching layer/pushing it to followers/creating rainbows).
