Docker Machine VMware Workstation Driver

Currently, the most popular unofficial driver for VMware and Docker Machine. This plugin for Docker Machine creates Docker hosts locally using VMware Workstation making it easier to use Docker tools for Windows users running VMware.

Open Source Docker Swarm

Docker just released the Docker for AWS as a fire and forget with no docs and no open code or information. This project alleviates that by providing an open-source implementation of all the components. It includes a reference implementation on AWS with Terraform and five containers with the tools to bootstrap and "guide" the cluster.

Reference WordPress on an AWS Implementation

This is a demo implementation of WordPress on AWS, leveraging many technologies like EC2 AutoScaling, EFS, RDS MySQL, SSM, ALB, CloudFront, Terraform, Docker, and of course, WordPress.

It utilizes stateless WordPress nodes to allow for dynamic scaling and zero-downtime delpoyments.
