| // 3. Deploying a cluster of 1 vault server using the example Terraform code | ||
| // 4. Sshing into vault node to initialize the server and check that it booted unsealed | ||
| // 5. Increasing the the cluster size to 3 and check that new nodes are unsealed when they boot and join the cluster | ||
