# aws-cdk.aws-fsx — The CDK Construct Library for AWS::FSx

License: permissive · Maintenance: active · Downloads: 105.7K/mo

## What it is and what it does

This is an AWS CDK v1 construct library for Amazon FSx, a fully managed file storage service. It provides Python classes to define FSx file systems declaratively as part of your infrastructure-as-code stack, supporting both Lustre (for high-performance computing, machine learning, and video processing workloads) and Windows File Server deployments. The library handles VPC integration, security group configuration, and mount-point management through a higher-level abstraction over CloudFormation primitives.

The package is no longer maintained; AWS CDK v1 reached end-of-support on 2023-06-01. While the library remains functional for existing stacks, new projects should use AWS CDK v2 instead. The package depends on eight runtime modules from the CDK ecosystem (EC2, IAM, KMS, core, constructs, jsii, publication, typeguard) and supports Python 3.7 through 3.11.

Use it for:

- Define a Lustre file system for HPC or machine learning workloads as part of a CDK v1 stack
- Provision FSx storage with automatic VPC and security group configuration using infrastructure-as-code
- Mount FSx file systems on EC2 instances by exposing DNS and mount names through CDK constructs
- Import and reference existing FSx file systems into CDK stacks using file system attributes

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides AWS CDK constructs for defining and managing Amazon FSx file systems (Lustre and Windows File Server) as infrastructure-as-code in Python.

No for new projects—AWS CDK v1 is end-of-support as of 2023-06-01 and this package is no longer updated. Migrate to AWS CDK v2 instead. Only install if maintaining an existing CDK v1 stack that already uses this library and migration is not immediately feasible.

## Install

pip install aws-cdk-aws-fsx
uv add aws-cdk-aws-fsx
poetry add aws-cdk-aws-fsx

## Installing aws-cdk.aws-fsx

Before you install: Low install friction with standard wheel distribution. Package is marked inactive (Development Status 7) and reached end-of-support on 2023-06-01; AWS CDK v1 is no longer updated and users should migrate to AWS CDK v2.

License in practice: Licensed under Apache-2.0 (permissive), allowing commercial and private use with attribution.

Quickstart:

pip install aws-cdk.aws-fsx

import aws_cdk.aws_fsx as fsx

file_system = fsx.LustreFileSystem(self, "FsxLustreFileSystem",
    lustre_configuration=fsx.LustreConfiguration(
        deployment_type=fsx.LustreDeploymentType.SCRATCH_2
    ),
    storage_capacity_gi_b=1200,
    vpc=vpc,
    vpc_subnet=vpc.private_subnets[0]
)

Requires AWS CDK v1 runtime dependencies (aws-cdk.aws-ec2, aws-cdk.aws-iam, aws-cdk.core, constructs). Package is end-of-support; new projects should use AWS CDK v2.

Verify before relying:

- Whether migration tooling or compatibility layer exists for moving existing CDK v1 FSx code to v2
- Current adoption rate and community support status for v1 FSx constructs post-EOL
