Your cluster has been provisioned! - To prepare your environment, run the
following:

```
export NOMAD_ADDR=http://${aws_instance.server[0].public_ip}:4646
export CONSUL_HTTP_ADDR=http://${aws_instance.server[0].public_ip}:8500
export NOMAD_E2E=1
```

Then you can run e2e tests with:

```
go test -v ./e2e
```

ssh into nodes with:
```
# server
ssh -i keys/${local.random_name}.pem ubuntu@${aws_instance.server[0].public_ip}

# clients
%{ for ip in aws_instance.client_linux.*.public_ip ~}
ssh -i keys/${local.random_name}.pem ubuntu@${ip}
%{ endfor ~}
```
EOM
