이 페이지에서는 고객 관리 암호화 키를 사용하는 Redis용 Memorystore 인스턴스를 만드는 방법을 설명합니다. 또한 CMEK를 사용하는 인스턴스를 관리하는 방법도 제공합니다. Memorystore의 고객 관리 암호화 키에 대한 자세한 내용은 고객 관리 암호화 키를 참조하세요.
Memorystore 인스턴스를 만들려는 동일한 리전에 키 링 및 키를 사용하는 것으로 시작합니다.
Redis 인스턴스 만들기 안내에 따라 고객 관리 암호화 키를 사용 설정하는 단계까지 수행한 후 이 안내로 돌아옵니다.
고객 관리 암호화 키(CMEK) 사용을 선택합니다.
드롭다운 메뉴를 사용하여 키를 선택합니다.
Memorystore 서비스 계정에 필요한 권한이 부여되지 않았으면 다음 텍스트 상자가 표시됩니다.
The service-[PROJECT-NUMBER]@cloud-redis.iam.gserviceaccount.com service
account does not have the "cloudkms.cryptoKeyEncrypterDecrypter" role.
Verify the service account has permission to encrypt/decrypt with the
selected key.
부여 버튼을 클릭하여 Memorystore 서비스 계정에 역할 권한을 부여합니다.
인스턴스에 원하는 구성을 선택한 후 만들기 버튼을 클릭하여 CMEK가 사용 설정된 Redis용 Memorystore 인스턴스를 만듭니다.

고객 관리 암호화 키를 사용하는 인스턴스를 만들려면 VARIABLES를 적합한 값으로 바꿔서 다음 명령어를 입력합니다.

It also provides instructions for\nmanaging instances that use CMEK. For more information about customer-managed\nencryption keys for Memorystore, see [Customer-managed encryption keys](/memorystore/docs/redis/cmek).\n| **Note:** You cannot enable CMEK on existing Memorystore for Redis instances.\n\nBefore you begin\n----------------\n\n1. Make sure you have the Redis Admin [role](/memorystore/docs/redis/access-control)\n on your user account.\n\n [Go to the IAM page](https://console.cloud.google.com/iam-admin/iam)\n\nWorkflow to create an instance that uses CMEK\n---------------------------------------------\n\n1. [Create a keyring](/kms/docs/creating-keys#create_a_key_ring) and\n [create a key](/kms/docs/creating-keys#create_a_key)\n in the location where you want the Memorystore instance to be.\n\n2. Copy or write down the key ID (KMS_KEY_ID), the location of the key, and the\n ID (KMS_KEYRING_ID) for the keyring. You need this information when granting\n the service account access to the key.\n\n3. [Grant the Memorystore service account access to the key](/memorystore/docs/redis/configure-cmek#granting_the_service_account_access_to_the_key).\n\n4. Go to a project and [create a Memorystore for Redis instance with CMEK enabled](#creating_a_memorystore_for_redis_instance_that_uses_cmek)\n in the same region as the keyring and key.\n\nYour Memorystore for Redis instance is now enabled with CMEK.\n\nCreating a key and keyring\n--------------------------\n\nFollow instructions to [create a keyring](/kms/docs/creating-keys#create_a_key_ring)\nand [create a key](/kms/docs/creating-keys#create_a_key). Both must be in the\nsame region as your Redis instance. The key can be from a different project, as\nlong as the key is in the same region. Also, the key must use the [symmetric encryption algorithn](/kms/docs/algorithms#symmetric_encryption_algorithms).\n\nGranting the service account access to the key\n----------------------------------------------\n\nIn order to create a Redis instance that uses CMEK first you must grant a\nspecific Memorystore service account access to the key. Grant\naccess to the Memorystore service account that uses the following\nformat:\n\n`service-[PROJECT-NUMBER]@cloud-redis.iam.gserviceaccount.com` \n\n### Console\n\nWhen using the console, you grant the service account access to the key as\npart of the steps for [creating a redis instance that uses CMEK](/memorystore/docs/redis/configure-cmek#creating_a_memorystore_for_redis_instance_that_uses_cmek).\n\n### gcloud\n\nTo grant the service account access to the key, run the following command\nreplacing \u003cvar translate=\"no\"\u003eVARIABLES\u003c/var\u003e with appropriate values: \n\n```\ngcloud kms keys add-iam-policy-binding [KMS_KEY_ID] \\\n--location=[REGION_ID] \\\n--keyring=[KMS_KEYRING_ID] \\\n--member=serviceAccount:service-[PROJECT-NUMBER]@cloud-redis.iam.gserviceaccount.com \\\n--role=roles/cloudkms.cryptoKeyEncrypterDecrypter\n```\n\nCreating a Memorystore for Redis instance that uses CMEK\n--------------------------------------------------------\n\n| **Note:** You can't enable customer-managed encryption keys on existing instances.\n\nTo create an instance with customer-managed encryption keys: \n\n### Console\n\n1. Begin by [having a keyring and key](/memorystore/docs/redis/configure-cmek#creating_a_key_and_keyring)\n in the same region where you want to create your Memorystore instance.\n\n2. Follow the instructions at [Creating a Redis instance on a VPC network](/memorystore/docs/redis/create-manage-instances#creating_a_redis_instance_on_a_vpc_network)\n until you reach the step for enabling a customer-managed encryption key,\n then return to these instructions.\n\n3. Select **Use a customer-managed encryption key (CMEK)**.\n\n4. Use the dropdown menu to select your key.\n\n5. If the Memorystore service account has not been granted the\n permissions it needs, a text box appears saying:\n\n `The service-[PROJECT-NUMBER]@cloud-redis.iam.gserviceaccount.com service\n account does not have the \"cloudkms.cryptoKeyEncrypterDecrypter\" role.\n Verify the service account has permission to encrypt/decrypt with the\n selected key.`\n - Click the **Grant** button to grant the role permission to the Memorystore service account.\n6. Finish selecting your desired configurations for your instance, and click\n the **Create** button to create your CMEK enabled Memorystore for Redis\n instance.\n\n### gcloud\n\nTo create an instance that uses customer-managed encryption keys enter the\nfollowing command, replacing \u003cvar translate=\"no\"\u003eVARIABLES\u003c/var\u003e with appropriate values: \n\n```\ngcloud redis instances create [INSTANCE_ID] \\\n--size=[SIZE] \\\n--region=[REGION_ID] \\\n--customer-managed-key=projects/[PROJECT_NAME]/locations/[REGION_ID]/keyRings/[KEYRING_NAME]/cryptoKeys/[KEY_NAME]\n```\n\nViewing key information for a CMEK-enabled instance\n---------------------------------------------------\n\nFollow these instructions to see if CMEK is enabled for your instance, and to\nview the active key. \n\n### Console\n\n1. In the Google Cloud Console, go to the Memorystore for Redis Instances page.\n\n [Memorystore for Redis](https://console.cloud.google.com/memorystore/redis/instances?)\n2. View the *Instance details* page for your instance by clicking your\n *Instance ID*.\n\n3. Click the **Security** tab.\n\n4. The **Encryption with a customer managed key** section contains a link to the\n active key, and shows the key reference path. If this section does not appear,\n CMEK is not enabled for your instance.\n\n### gcloud\n\nTo verify if CMEK is enabled, and to see the key reference, view the\n`customerManagedKey` field by running the following command: \n\n```\ngcloud redis instances describe INSTANCE_ID \\\n--project=PROJECT \\\n--region=REGION\n```\n\nDisabling and re-enabling key versions\n--------------------------------------\n\nFor information about what happens when you disable, enable, destroy, or\nre-enable a key version, see [Behavior of destroying/disabling a CMEK key version](/memorystore/docs/redis/cmek#behavior_of_destroyingdisabling_a_cmek_key_version).\n\nFor instructions on how to disable and re-enable key versions, see [Enabling and disabling key versions](/kms/docs/enable-disable).\n\nFor instructions on how to disable and re-enable key versions, see [Destroying and restoring key versions](/kms/docs/destroy-restore).\n\nWhat's next\n-----------\n\n- Learn more about [Redis AUTH](/memorystore/docs/redis/auth-overview).\n- Learn more about [In-transit encryption](/memorystore/docs/redis/in-transit-encryption)."]]
