Step 2: Create Amazon EFS resources

To create a file system

• Create a file system with the optional Name tag.

  1. At the command prompt, run the following Amazon CLI create-file-system command.

     $  aws efs create-file-system \
     --encrypted \
     --creation-token FileSystemForWalkthrough1 \
     --tags Key=Name,Value=SomeExampleNameValue \
     --region us-west-2 \
     --profile adminuser

     You get the following response.

     {
         "OwnerId": "111122223333",
         "CreationToken": "FileSystemForWalkthrough1",
         "FileSystemId": "fs-c657c8bf",
         "CreationTime": 1548950706.0,
         "LifeCycleState": "creating",
         "NumberOfMountTargets": 0,
         "SizeInBytes": {
             "Value": 0,
             "ValueInIA": 0,
             "ValueInStandard": 0
         },
         "PerformanceMode": "generalPurpose",
         "Encrypted": true,
         "KmsKeyId": "arn:aws:kms:us-west-2:111122223333:a5c11222-7a99-43c8-9dcc-abcdef123456",
         "ThroughputMode": "bursting",
         "Tags": [
             {
                 "Key": "Name",
                 "Value": "SomeExampleNameValue"
             }
         ]
     }

  2. Note the FileSystemId value. You need this value when you create a mount target for this file system in Step 2.3: Create a mount target.

To enable lifecycle management

• At the command prompt, run the following Amazon CLI put-lifecycle-configuration command.

  $  aws efs put-lifecycle-configuration \
  --file-system-id fs-c657c8bf \
  --lifecycle-policies TransitionToIA=AFTER_30_DAYS \
  --region us-west-2 \
  --profile adminuser
            

  You get the following response.

  {
    "LifecyclePolicies": [
      {
          "TransitionToIA": "AFTER_30_DAYS"
      }
    ]
  }   
            

1. Make sure you have the following information:

   • ID of the file system (for example, fs-example) for which you are creating the mount target.

   • VPC subnet ID where you launched the EC2 instance in Step 1.

     For this walkthrough, you create the mount target in the same subnet in which you launched the EC2 instance, so you need the subnet ID (for example, subnet-example).

   • ID of the security group you created for the mount target in the preceding step.

2. At the command prompt, run the following Amazon CLI create-mount-target command.

   $ aws efs create-mount-target \
   --file-system-id file-system-id \
   --subnet-id  subnet-id \
   --security-group ID-of-the security-group-created-for-mount-target \
   --region us-west-2 \
   --profile adminuser

   You get the following response.

   {
       "MountTargetId": "fsmt-example",
       "NetworkInterfaceId": "eni-example",
       "FileSystemId": "fs-example",
       "PerformanceMode" : "generalPurpose",
       "LifeCycleState": "available",
       "SubnetId": "fs-subnet-example",
       "OwnerId": "account-id",
       "IpAddress": "xxx.xx.xx.xxx"
   }

3. You can also use the describe-mount-targets command to get descriptions of mount targets you created on a file system.

   $ aws efs describe-mount-targets \
   --file-system-id file-system-id \
   --region us-west-2 \
   --profile adminuser
