A low-level client representing Amazon Elastic File System (EFS):
import boto3
client = boto3.client('efs')
These are the available methods:
Check if an operation can be paginated.
Creates a new, empty file system. The operation requires a creation token in the request that Amazon EFS uses to ensure idempotent creation (calling the operation with same creation token has no effect). If a file system does not currently exist that is owned by the caller's AWS account with the specified creation token, this operation does the following:
Otherwise, this operation returns a FileSystemAlreadyExists error with the ID of the existing file system.
Note
For basic use cases, you can use a randomly generated UUID for the creation token.
The idempotent operation allows you to retry a CreateFileSystem call without risk of creating an extra file system. This can happen when an initial call fails in a way that leaves it uncertain whether or not a file system was actually created. An example might be that a transport level timeout occurred or your connection was reset. As long as you use the same creation token, if the initial call had succeeded in creating a file system, the client can learn of its existence from the FileSystemAlreadyExists error.
Note
The CreateFileSystem call returns while the file system's lifecycle state is still creating . You can check the file system creation status by calling the DescribeFileSystems operation, which among other things returns the file system state.
This operation also takes an optional PerformanceMode parameter that you choose for your file system. We recommend generalPurpose performance mode for most file systems. File systems using the maxIO performance mode can scale to higher levels of aggregate throughput and operations per second with a tradeoff of slightly higher latencies for most file operations. The performance mode can't be changed after the file system has been created. For more information, see Amazon EFS: Performance Modes .
After the file system is fully created, Amazon EFS sets its lifecycle state to available , at which point you can create one or more mount targets for the file system in your VPC. For more information, see CreateMountTarget . You mount your Amazon EFS file system on an EC2 instances in your VPC by using the mount target. For more information, see Amazon EFS: How it Works .
This operation requires permissions for the elasticfilesystem:CreateFileSystem action.

Creates a mount target for a file system. You can then mount the file system on EC2 instances by using the mount target.
You can create one mount target in each Availability Zone in your VPC. All EC2 instances in a VPC within a given Availability Zone share a single mount target for a given file system. If you have multiple subnets in an Availability Zone, you create a mount target in one of the subnets. EC2 instances do not need to be in the same subnet as the mount target in order to access their file system. For more information, see Amazon EFS: How it Works .
In the request, you also specify a file system ID for which you are creating the mount target and the file system's lifecycle state must be available . For more information, see DescribeFileSystems .
In the request, you also provide a subnet ID, which determines the following:
After creating the mount target, Amazon EFS returns a response that includes, a MountTargetId and an IpAddress . You use this IP address when mounting the file system in an EC2 instance. You can also use the mount target's DNS name when mounting the file system. The EC2 instance on which you mount the file system by using the mount target can resolve the mount target's DNS name to its IP address. For more information, see How it Works: Implementation Overview .
Note that you can create mount targets for a file system in only one VPC, and there can be only one mount target per Availability Zone. That is, if the file system already has one or more mount targets created for it, the subnet specified in the request to add another mount target must meet the following requirements:
If the request satisfies the requirements, Amazon EFS does the following:
Each Amazon EFS mount target has one corresponding requester-managed EC2 network interface. After the network interface is created, Amazon EFS sets the NetworkInterfaceId field in the mount target's description to the network interface ID, and the IpAddress field to its address. If network interface creation fails, the entire CreateMountTarget operation fails.
Note
The CreateMountTarget call returns only after creating the network interface, but while the mount target state is still creating , you can check the mount target creation status by calling the DescribeMountTargets operation, which among other things returns the mount target state.
We recommend that you create a mount target in each of the Availability Zones. There are cost considerations for using a file system in an Availability Zone through a mount target created in another Availability Zone. For more information, see Amazon EFS . In addition, by always using a mount target local to the instance's Availability Zone, you eliminate a partial failure scenario. If the Availability Zone in which your mount target is created goes down, then you can't access your file system through that mount target.
This operation requires permissions for the following action on the file system:

Deletes a file system, permanently severing access to its contents. Upon return, the file system no longer exists and you can't access any contents of the deleted file system.
You can't delete a file system that is in use. That is, if the file system has any mount targets, you must first delete them. For more information, see DescribeMountTargets and DeleteMountTarget .
Note
The DeleteFileSystem call returns while the file system state is still deleting . You can check the file system deletion status by calling the DescribeFileSystems operation, which returns a list of file systems in your account. If you pass file system ID or creation token for the deleted file system, the DescribeFileSystems returns a 404 FileSystemNotFound error.
This operation requires permissions for the elasticfilesystem:DeleteFileSystem action.

Deletes the specified mount target.
This operation forcibly breaks any mounts of the file system by using the mount target that is being deleted, which might disrupt instances or applications using those mounts. To avoid applications getting cut off abruptly, you might consider unmounting any mounts of the mount target, if feasible. The operation also deletes the associated network interface. Uncommitted writes might be lost, but breaking a mount target using this operation does not corrupt the file system itself. The file system you created remains. You can mount an EC2 instance in your VPC by using another mount target.
This operation requires permissions for the following action on the file system:
Note
The DeleteMountTarget call returns while the mount target state is still deleting . You can check the mount target deletion by calling the DescribeMountTargets operation, which returns a list of mount target descriptions for the given file system.

Returns the description of a specific Amazon EFS file system if either the file system CreationToken or the FileSystemId is provided. Otherwise, it returns descriptions of all file systems owned by the caller's AWS account in the AWS Region of the endpoint that you're calling.
When retrieving all file system descriptions, you can optionally specify the MaxItems parameter to limit the number of descriptions in a response. Currently, this number is automatically set to 10. If more file system descriptions remain, Amazon EFS returns a NextMarker , an opaque token, in the response. In this case, you should send a subsequent request with the Marker request parameter set to the value of NextMarker .
To retrieve a list of your file system descriptions, this operation is used in an iterative process, where DescribeFileSystems is called first without the Marker and then the operation continues to call it with the Marker parameter set to the value of the NextMarker from the previous response until the response has no NextMarker .
The order of file systems returned in the response of one DescribeFileSystems call and the order of file systems returned across the responses of a multi-call iteration is unspecified.
This operation requires permissions for the elasticfilesystem:DescribeFileSystems action.

Returns an object that can wait for some condition.
Modifies the set of security groups in effect for a mount target.
When you create a mount target, Amazon EFS also creates a new network interface. For more information, see CreateMountTarget . This operation replaces the security groups in effect for the network interface associated with a mount target, with the SecurityGroups provided in the request. This operation requires that the network interface of the mount target has been created and the lifecycle state of the mount target is not deleted .
The operation requires permissions for the following actions:

Enables lifecycle management by creating a new LifecycleConfiguration object. A LifecycleConfiguration object defines when files in an Amazon EFS file system are automatically transitioned to the lower-cost EFS Infrequent Access (IA) storage class. A LifecycleConfiguration applies to all files in a file system.
Each Amazon EFS file system supports one lifecycle configuration, which applies to all files in the file system. If a LifecycleConfiguration object already exists for the specified file system, a PutLifecycleConfiguration call modifies the existing configuration. A PutLifecycleConfiguration call with an empty LifecyclePolicies array in the request body deletes any existing LifecycleConfiguration and disables lifecycle management.
In the request, specify the following:
This operation requires permissions for the elasticfilesystem:PutLifecycleConfiguration operation.
To apply a LifecycleConfiguration object to an encrypted file system, you need the same AWS Key Management Service (AWS KMS) permissions as when you created the encrypted file system.
