How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

Lets get some context first.

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

sudo yum install update
sudo yum groupinstall -y "Development Tools"
sudo yum install -y python-devel libpng-devel freetype-devel gcc72-c++

If you want to use docker, you can use the following command:

 docker run -it lambci/lambda:build-python3.7 bash

	from multiprocessing import Pool as MPool
	from time import sleep
	import datetime
	import multiprocessing
	import random

	def time_request():
	from gevent import monkey; monkey.patch_socket
	from jsonrequester import JsonRequester

	import math
	import numpy
	import numpy.random as nrand

	Note - for some of the metrics the absolute value is returns. This is because if the risk (loss) is higher we want to
	discount the expected excess return from the portfolio by a higher amount. Therefore risk should be positive.
