GCE and GCS CMEK via centralized Cloud KMS
This example creates a sample centralized Cloud KMS configuration, and uses it to implement CMEK for Cloud Storage and Compute Engine in a separate project.
The example is designed to match real-world use cases with a minimum amount of resources, and be used as a starting point for scenarios where application projects implement CMEK using keys managed by a central team. It also includes the IAM wiring needed to make such scenarios work.
This is the high level diagram:
Managed resources and services
This sample creates several distinct groups of resources:
- projects
- Cloud KMS project
- Service Project configured for GCE instances and GCS buckets
- networking
- VPC network
- One subnet
- Firewall rules for SSH access via IAP and open communication within the VPC
- IAM
- One service account for the GGE instance
- KMS
- One key ring
- One crypto key (Protection level: software) for Cloud Engine
- One crypto key (Protection level: software) for Cloud Storage
- GCE
- One instance encrypted with a CMEK Cryptokey hosted in Cloud KMS
- GCS
- One bucket encrypted with a CMEK Cryptokey hosted in Cloud KMS
