Containers Workshop

Containers Workshop is a ansible playbook to provision docker/container servers in AWS. This playbook uses Ansible to wrap Terraform, for provisioning AWS infrastructure and nodes. To find more info about Terraform check here

These modules all require that you have AWS API keys available to use to provision AWS resources. You also need to have IAM permissions set to allow you to create resources within AWS. There are several methods for setting up you AWS environment on you local machine.

Export the AWS API Keys by hand;

export AWS_SECRET_ACCESS_KEY='****************TFHJw'

This repo also requires that you have Ansible installed on your local machine. For the most upto date methods of installing Ansible for your operating system check here.

This repo also requires that Terraform be installed if you are using the aws.infra.terraform role. For the most upto data methods of installing Terraform for your operating system check here
