Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:

'''
This script emulates a stand-alone Python based client. It relies on Boto3 to access AWS, but
requires your Django server to have an API for your user to access Cognito based credentials

Because of Cognito, the client (this script) will only get temporary AWS credentials associated
to your user and only your user, and based on whatever you configure your AIM Policy to be.

Most Cognito examples demonstrate how to use Cognito for Mobile Apps, so this scripts demonstrate
how to create a stand-alone Python script but operating similarly to these apps.

##Using Let's Encrypt certificates with AWS API Gateway

Before starting off with API Gateway set up it's worth mentioning that certificate configuration for this particular service is so far isn't well integrated, therefore different from other AWS services. Despite it using CloudFrount to serve on custom domains it won't let you customize distributions it creates, however all the limitations of CloudFront naturally apply to API Gateway. The most important in this case is the size of the key, which is limited by 2048 bit. Many tutorials provide ready to use terminal commands that have the key size preset at 4096 bit for the sake of better security. This won't work with API Gateway and you'll get an error message about certificate's validity or incorrect chain which won't suggest you the real cause of the issue. Another consideration is that to add a custom domain to API Gateway you have to have a certif
