Too quick? How does it work internally?
Install AWS CLI (https://docs.aws.amazon.com/cli/latest/userguide/installing.html)
$ sudo pip install awscli
$ aws configure
$ aws --version
Clone WordPress AWS Scaler git repo (https://github.com/plesk/wordpress-aws-scaler)
$ git clone https://github.com/plesk/wordpress-aws-scaler.git
$ cd wordpress-aws-scaler
Build Docker Image and Upload to Docker Hub (https://hub.docker.com/explore/)
$ docker build -t janloeffler/wordpress-aws-scaler:latest -t janloeffler/wordpress-aws-scaler:0.2 .
