During the deployment process, a service account created on your behalf uses these permissions for the duration of the deployment.
The service account uses these permissions to install the backup/recovery appliance
The service account is highly privileged in the target, VPC project, and consumer projects during the installation. Most of these permissions are removed as the installation progresses. The following table contains the roles granted to the service account and the permissions needed within each role.
| Role | Permissions needed | If Shared VPC, then assign to: |
|---|---|---|
| resourcemanager.projectIamAdmin | resourcemanager.projects.getIamPolicy | VPC Owner, Backup Admin, and Workload projects |
| resourcemanager.projects.setIamPolicy | VPC Owner, Backup Admin, and Workload projects | |
| iam.serviceAccountUser | iam.serviceAccounts.actAs | Workload project |
| iam.serviceAccountTokenCreator | iam.serviceAccounts.getOpenIdToken | Workload project |
| cloudkms.admin | cloudkms.keyRings.create | VPC Owner, Backup Admin, and Workload projects |
| cloudkms.keyRings.getIamPolicy | VPC Owner, Backup Admin, and Workload projects | |
| cloudkms.keyRings.setIamPolicy | VPC Owner, Backup Admin, and Workload projects | |
| logging.logWriter | logging.logs.write | Workload project |
| compute.admin | compute.instances.create | Workload project |
| compute.instances.delete | Workload project | |
| compute.disks.create | Workload project | |
| compute.disks.delete | Workload project | |
| compute.instances.setMetadata | Workload project | |
| compute.subnetworks.get | VPC project | |
| compute.subnetworks.use | VPC project | |
| compute.subnetworks.setPrivateIpGoogleAccess | VPC project | |
| compute.firewalls.create | VPC project | |
| compute.firewalls.delete | VPC project | |
| backupdr.admin | backupdr.managementservers.manageInternalACL | Backup Admin project |
After installation is finished, for daily operation on the workload project
All of the permissions required for deployment and installation are removed
except for iam.serviceAccountUser and iam.serviceAccounts.actAs. Two cloudkms
roles needed for daily operation are added, restricted to a single key ring.
| Role | Permissions needed |
|---|---|
| iam.serviceAccountUser | iam.serviceAccounts.actAs |
| cloudkms.cryptoKeyEncrypterDecrypter* | cloudkms.cryptoKeyVersions.useToDecrypt |
| cloudkms.cryptoKeyVersions.useToEncrypt | |
| cloudkms.admin* | cloudkms.keyRings.get |
| backupdr.computeEngineOperator* | All permissions listed in the role. |
| backupdr.cloudStorageOperator** | All permissions listed in the role. |
* The cloudkms roles are on a single key ring.
** The cloudStorageOperator role is on buckets with names that start with
the name of the backup/recovery appliance.
Permissions used to create a firewall on the project
These IAM permissions are used to create a firewall on the project that owns the VPC only during firewall creation.
compute.firewalls.create
compute.firewalls.delete
compute.firewalls.get
compute.firewalls.list
compute.firewalls.update
compute.networks.list
compute.networks.get
compute.networks.updatePolicy
All other permissions are no longer needed after installation.
