In this entry I will address the subject of the autoscale of the Stateful Set Issues source, at this moment Kubernetes does not support to auto scale of the Stateful Set, to solve this need, I decided to program two slug-autoscaler tools to monitor the replicas to modify them according to the state of the CPU and slug-labalancer to customize the load balance. I also want to include support for properly scaling crunchy-containers.

How to use terminal on Windows without going crazy…

Windows is really horrible system for developers and especially for devops. It doesn’t even have a usable terminal and shell, so working with command line is really pain in the ass. If you really don’t want to switch to any usable system (OS X, Linux, BSD…), then this guide should help you to setup somewhat reasonable environment – usable terminal, proper shell, ssh client, git and Sublime Text as a default editor for shell.

Install stuff

Download and install Git for Windows* with:
- [✘] Use Git from the Windows Command Prompt

[✘] Checkout as-is, commit Unix-style line endings
