Create a key ring

This page shows you how to create a key ring in Cloud KMS. A key ring is the root resource for Cloud KMS keys and key versions. Each key ring exists within a given location. For more information about Cloud KMS resources, see Cloud KMS resources .

Before you begin

Before completing the tasks on this page, you need the following:

A Google Cloud project resource to contain your Cloud KMS resources. This project is called your key project . We recommend that your key project does not contain any other Google Cloud resources. Enable the Cloud KMS API on your key project.
Enable the API
The name of the location where you want to create your key ring. Choose a location that is near your other resources and that supports your chosen protection level . To view available locations and the protection levels they support, see Cloud KMS locations .

Required roles

To get the permissions that you need to create key rings, ask your administrator to grant you the Cloud KMS Admin ( roles/cloudkms.admin ) IAM role on the project or a parent resource. For more information about granting roles, see Manage access to projects, folders, and organizations .

This predefined role contains the permissions required to create key rings. To see the exact permissions that are required, expand the Required permissionssection:

Required permissions

The following permissions are required to create key rings:

cloudkms.keyRings.create
cloudkms.keyRings.get
cloudkms.keyRings.list
cloudkms.locations.get
cloudkms.locations.list
resourcemanager.projects.get

You might also be able to get these permissions with custom roles or other predefined roles .

Create a key ring

Follow these steps to create a key ring for your new key. If you want to use an existing key ring instead, you can create a key .

Console

Go to the Key Managementpage in the Google Cloud console.

Go to Key Management
Click Create key ring.
For Key ring name, enter a name for your key ring.
For Key ring location, select a location like "us-east1" .

Note: Choose a location that is near the resources you want to protect. For CMEK usage, your key ring should be in the same location as the resources you use it with. For Cloud EKM keys, the location must be physically close to your external key manager (EKM) vendor.
Click Create.

gcloud

In the Google Cloud console, activate Cloud Shell.

Activate Cloud Shell
In your environment, run the gcloud kms keyrings create command:
```
 gcloud  
kms  
keyrings  
create  
 KEY_RING 
  
 \ 
  
--location  
 LOCATION 
 
```
Replace the following:
- KEY_RING : the name of the key ring that contains the key.
- LOCATION : the Cloud KMS location of the key ring.
For information on all flags and possible values, run the command with the --help flag.

API

These examples use curl as an HTTP client to demonstrate using the API. For more information about access control, see Accessing the Cloud KMS API .

curl "https://cloudkms.googleapis.com/v1/projects/ PROJECT_ID 
/locations/ LOCATION 
/keyRings?key_ring_id= KEY_RING 
" \
    --request "POST" \
    --header "authorization: Bearer TOKEN 
"

Replace the following:

PROJECT_ID : the ID of the project that contains the key ring.
KEY_RING : the name of the key ring that contains the key.
LOCATION : the Cloud KMS location of the key ring.

See the KeyRing.create API documentation for more information.
