Openshift 3.11 on AWS via Terraform

Deploy Openshift Container Platform (OCP) v3.11 to Amazon Web Services (AWS) via Terraform

Creates a basic OCP v3.11 cluster with a single master node, single compute node, and a bastion.

To Use

(Optional) Copy/rename terraform.tfvars.example to terraform.tfvars and fill in the information (otherwise these will be prompted on apply):
```
mv terraform.tfvars.example terraform.tfvars
```
Initialize and apply the Terraform configuration. Provide verification to deploy OCP v3.11 (add -auto-approve to apply without user verification):
```
terraform init && terraform apply
```
The Terraform output provides access credentials for the cluster. (NOTE: You can administer the cluster directly by SSH-ing to the Bastion and then SSH-ing to the Master, where oc is already configured and logged in with the default Cluster Administrator, system:admin):
- To see all output:
```
terraform output
```
- To see only one output (handy for copy/paste or scripts):
```
terraform output <variable>
```
- Example: SSH directly to Master node through Bastion
```
$(terraform output bastion_ssh) -A -t ssh $(terraform output private_dns_master)
```
To destroy the cluster and its resources:
```
terraform destroy
```
