The vfarcic/cloud-provisioning (https://github.com/vfarcic/cloud-provisioning) repository already has the Packer and Terraform configurations we'll use. They are located in the terraform/aws directory:
The first step is to use Packer to create an Amazon Machine Image (AMI). To do that, we'll need AWS access keys set as environment variables.

export AWS_ACCESS_KEY_ID=[...]export AWS_SECRET_ACCESS_KEY=[...]export AWS_DEFAULT_REGION=us-east-1
Please replace [...] with the actual values.
We'll instantiate all Swarm nodes ...
