Limiting docker resource usage on Linux

The Problem

Linux doesn't have a dedicated Docker application like Windows and OSX that allows you to easily place resource constraints on the docker daemon. So if you spin up a bunch of resource hungry containers, it'll slow your computer to a crawl and/or start a fire.

Observe the Problem

Uses the image from https://hub.docker.com/r/polinux/stress to see the issue in practice. Run these beforehand to see just how much CPU/RAM docker can take up, and then run them making the adjustments below to see how the docker containers get limited.

You'll want to install ctop and have it running to be able to monitor the container usage:

sudo wget https://github.com/bcicen/ctop/releases/download/v0.7.3/ctop-0.7.3-linux-amd64 -O /usr/local/bin/ctop

Method for easily adding colors to your bash script outputs.
#!/bin/bash
# Sets variables that can be used to add color to text in bash scripts.
# Must use "echo -e" or "printf" for colors to work
# Load this file in your bash scripts by including this line:
# source /path/to/this/file

# Example usage:
# echo -e "${BLUE}This is blue.${YELLOW}And this is yellow.${NC}And this is the defaul color."

Test for Newsletter
## Example Newsletter Article##
This is a example of how to create an article for the Rural Reader Newsletter using [StackEdit.io](http://stackedit.io/editor) and Markdown.
StackEdit.io is an online editor that allows you to quickly create web documents. StackEdit.io provides a simple, easy interface for [Markdown](http://daringfireball.net/projects/markdown/), a document markup language used to create html from plain text.
The beauty of StackEdit.io is you don't have to learn much about Markdown at all. You can use it just like Microsoft Word:
1. Enter your text in the window on the left
2. Use the buttons at the top to format your text
3. Preview the completed page on the right
