# Configure and create the cluster
<a name="creating-the-cluster-v3"></a>

The following is an example cluster configuration that includes an Amazon Elastic Block Store shared file system with encryption.

```
Region: {{eu-west-1}}
Image:
  Os: alinux2
HeadNode:
  InstanceType: t2.micro
  Networking:
    SubnetId: subnet-{{abcdef01234567890}}
  Ssh:
    KeyName: {{my-ssh-key}}
  Iam:
    AdditionalIamPolicies:
      - Policy: arn:aws:iam::{{123456789012}}:policy/ParallelClusterKmsPolicy
Scheduling:
  Scheduler: slurm
  SlurmQueues:
    - Name: {{q1}}
      ComputeResources:
        - Name: t2micro
          InstanceType: t2.micro
          MinCount: 0
          MaxCount: 10
      Networking:
        SubnetIds:
          - subnet-{{abcdef01234567890}}
      Iam:
        AdditionalIamPolicies:
          - Policy: arn:aws:iam::{{123456789012}}:policy/ParallelClusterKmsPolicy
SharedStorage:
  - MountDir: /shared/{{ebs1}}
    Name: {{shared-ebs1}}
    StorageType: Ebs
    EbsSettings:
      Encrypted: True
      KmsKeyId: {{abcd1234-ef56-gh78-ij90-abcd1234efgh5678}}
```

Replace the items in red text with your own values. Then, create a cluster that uses your AWS KMS key to encrypt your data in Amazon EBS.

The configuration is similar for Amazon EFS and FSx for Lustre file systems.

The Amazon EFS `SharedStorage` configuration is as follows.

```
...
SharedStorage:
  - MountDir: /shared/{{efs1}}
    Name: {{shared-efs1}}
    StorageType: Efs
    EfsSettings:
      Encrypted: True
      KmsKeyId: {{abcd1234-ef56-gh78-ij90-abcd1234efgh5678}}
```

The FSx for Lustre `SharedStorage` configuration is as follows.

```
...
SharedStorage:
  - MountDir: /shared/{{fsx1}}
    Name: {{shared-fsx1}}
    StorageType: FsxLustre
    FsxLustreSettings:
      StorageCapacity: {{1200}}
      DeploymentType: {{PERSISTENT_1}}
      PerUnitStorageThroughput: {{200}}
      KmsKeyId: {{abcd1234-ef56-gh78-ij90-abcd1234efgh5678}}
```
