Copy the following YAML into a file named `existing-volume.yaml` and complete\n your configuration by replacing the values:\n\n - \u003cvar translate=\"no\"\u003evolume-capacity\u003c/var\u003e: size of the volume. For example, `30Gi`. For more information on specifying volume capacity in Kubernetes, see the [Meaning of memory](https://kubernetes.io/docs/concepts/configuration/manage-compute-resources-container/#meaning-of-memory).\n - \u003cvar translate=\"no\"\u003estorage-class-name\u003c/var\u003e: the name of the StorageClass that\n provisions the volume.\n For example, you can use the default `standard-rwo`.\n\n | **Note:** A StorageClass is required to reference other attributes like `allowVolumeExpansion`, even if a volume is not dynamically provisioned.\n - \u003cvar translate=\"no\"\u003eebs-id\u003c/var\u003e: EBS [volume id](https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-volumes.html#examples).\n For example, `vol-05786ec9ec9526b67`.\n\n - \u003cvar translate=\"no\"\u003efs-type\u003c/var\u003e: The\n [file system](https://github.com/kubernetes-sigs/aws-ebs-csi-driver#createvolume-parameters)\n of the volume. For example, `ext4`.\n\n - \u003cvar translate=\"no\"\u003ezone\u003c/var\u003e: The AWS Availability Zone that hosts the EBS volume.\n For example, `us-east-1c`.\n\n apiVersion: v1\n kind: PersistentVolume\n metadata:\n name: \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-l devsite-syntax-l-Scalar devsite-syntax-l-Scalar-Plain\"\u003evolume-name\u003c/span\u003e\u003c/var\u003e\n annotations:\n pv.kubernetes.io/provisioned-by: ebs.csi.aws.com\n spec:\n capacity:\n storage: \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-l devsite-syntax-l-Scalar devsite-syntax-l-Scalar-Plain\"\u003evolume-capacity\u003c/span\u003e\u003c/var\u003e\n accessModes:\n - ReadWriteOnce\n persistentVolumeReclaimPolicy: Retain\n storageClassName: \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-l devsite-syntax-l-Scalar devsite-syntax-l-Scalar-Plain\"\u003estorage-class-name\u003c/span\u003e\u003c/var\u003e\n claimRef:\n name: my-pvc\n namespace: default\n csi:\n driver: ebs.csi.aws.com\n volumeHandle: \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-l devsite-syntax-l-Scalar devsite-syntax-l-Scalar-Plain\"\u003eebs-volume-id\u003c/span\u003e\u003c/var\u003e\n fsType: \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-l devsite-syntax-l-Scalar devsite-syntax-l-Scalar-Plain\"\u003efile-system-type\u003c/span\u003e\u003c/var\u003e\n nodeAffinity:\n required:\n nodeSelectorTerms:\n - matchExpressions:\n - key: topology.ebs.csi.aws.com/zone\n operator: In\n values:\n - \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-l devsite-syntax-l-Scalar devsite-syntax-l-Scalar-Plain\"\u003ezone\u003c/span\u003e\u003c/var\u003e\n\n2. Apply the YAML to your cluster\n\n kubectl apply -f existing-volume.yaml\n\n3. Confirm the creation of your PV\n\n kubectl describe pv \u003cvar translate=\"no\"\u003evolume-name\u003c/var\u003e\n\n The output of this command contains the status of the PV.\n\nUsing the volume with a PersistentVolumeClaim and Pod\n-----------------------------------------------------\n\nAfter you have imported your volume, you can create a PVC and a Pod that\nattaches the PVC.\n\nThe YAML below creates a PVC and attaches it to a Pod running the Nginx web\nserver. Copy it into a file named `nginx.yaml` and complete your configuration\nby replacing the values:\n\n- \u003cvar translate=\"no\"\u003estorage-class\u003c/var\u003e: The name of the StorageClass from the PersistentVolume you created previously. For example, `standard-rwo`.\n- \u003cvar translate=\"no\"\u003evolume-name\u003c/var\u003e: The name of the volume you created previously.\n- \u003cvar translate=\"no\"\u003evolume-capacity\u003c/var\u003e: size of the volume.

Apply the YAML to your cluster\n\n kubectl apply -f nginx.yaml\n\n2. Check the status of your Nginx instance with `kubectl describe`. The output\n should have a `STATUS` of `Running`.\n\n kubectl describe pod web-server\n\nUsing encrypted EBS volumes\n---------------------------\n\nIf your EBS volume is encrypted with the AWS Key Management Service (KMS), you\nneed to grant the GKE on AWS control plane AWS IAM role access to\nyour KMS key.\n\nTo get the AWS IAM role name, perform the following steps:\n\n1. Change to the directory with your GKE on AWS configuration.\n You created this directory when\n [Installing the management service](/kubernetes-engine/multi-cloud/docs/aws/previous-generation/how-to/installing-management).\n\n ```sh\n cd anthos-aws\n ```\n\n \u003cbr /\u003e\n\n2. Choose if you created your GKE on AWS environment with the\n `anthos-gke` tool or if you created your AWS IAM profiles manually.\n\n ### anthos-gke tool\n\n Use the `terraform output` command and search for the value of\n `iamInstanceProfile`. \n\n terraform output | grep iamInstanceProfile\n\n If you created your GKE on AWS environment with the `anthos-\n gke` tool, the output looks like the following: \n\n iamInstanceProfile: gke-\u003cvar translate=\"no\"\u003eCLUSTER_ID\u003c/var\u003e-controlplane\n iamInstanceProfile: gke-\u003cvar translate=\"no\"\u003eCLUSTER_ID\u003c/var\u003e-nodepool\n\n Where \u003cvar translate=\"no\"\u003eCLUSTER_ID\u003c/var\u003e is your cluster's ID. Copy the value of\n `gke-`\u003cvar translate=\"no\"\u003eCLUSTER_ID\u003c/var\u003e`-controlplane` for the following step.\n\n ### Manually created\n\n Examine the output of `terraform output` with the following command: \n\n terraform output | less\n\n Scroll through the output and find the iamInstanceProfile after the\n AWSCluster definition. \n\n kind: AWSCluster\n metadata:\n name: cluster-0\n spec:\n ...\n controlPlane:\n ...\n iamInstanceProfile: \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-l devsite-syntax-l-Scalar devsite-syntax-l-Scalar-Plain\"\u003eINSTANCE_PROFILE_NAME\u003c/span\u003e\u003c/var\u003e\n\n Copy the value of `INSTANCE_PROFILE_NAME` for the following\n step.\n3. To grant the control plane access to your EBS volumes, add the\n `gke-xxxxxx-controlplane` AWS IAM profile as a\n [Key User](https://docs.aws.amazon.com/kms/latest/developerguide/key-policy-default.html#key-policy-default-allow-users)\n to the AWS KMS key used to encrypt your EBS volume.\n\nWhat's next\n-----------\n\n- Use additional [storage drivers](/kubernetes-engine/multi-cloud/docs/aws/previous-generation/how-to/storage-drivers) with GKE on AWS."]]
