class aws_cdk.aws_lambda.FileSystem(*, arn, local_mount_path, connections=None, dependency=None, policies=None)

Bases: object

Represents the filesystem for the Lambda function.

ExampleMetadata:

infused

Example:

import aws_cdk.aws_ec2 as ec2 import aws_cdk.aws_efs as efs

create a new VPC

vpc = ec2.Vpc(self, "VPC")

create a new Amazon EFS filesystem

file_system = efs.FileSystem(self, "Efs", vpc=vpc)

create a new access point from the filesystem

access_point = file_system.add_access_point("AccessPoint", # set /export/lambda as the root of the access point path="/export/lambda", # as /export/lambda does not exist in a new efs filesystem, the efs will create the directory with the following createAcl create_acl=efs.Acl( owner_uid="1001", owner_gid="1001", permissions="750" ), # enforce the POSIX identity so lambda function will access with this identity posix_user=efs.PosixUser( uid="1001", gid="1001" ) )

fn = lambda_.Function(self, "MyLambda", # mount the access point to /mnt/msg in the lambda runtime environment filesystem=lambda_.FileSystem.from_efs_access_point(access_point, "/mnt/msg"), runtime=lambda_.Runtime.NODEJS_16_X, handler="index.handler", code=lambda_.Code.from_asset(path.join(__dirname, "lambda-handler")), vpc=vpc )

Parameters:

• arn (str) – ARN of the access point.
• local_mount_path (str) – mount path in the lambda runtime environment.
• connections (Optional[Connections]) – connections object used to allow ingress traffic from lambda function. Default: - no connections required to add extra ingress rules for Lambda function
• dependency (Optional[Sequence[IDependable]]) – array of IDependable that lambda function depends on. Default: - no dependency
• policies (Optional[Sequence[PolicyStatement]]) – additional IAM policies required for the lambda function. Default: - no additional policies required

Attributes

config

the FileSystem configurations for the Lambda function.

Static Methods

classmethod from_efs_access_point(ap, mount_path)

mount the filesystem from Amazon EFS.

Parameters:

• ap (IAccessPoint) – the Amazon EFS access point.
• mount_path (str) – the target path in the lambda runtime environment.

Return type:

FileSystem
