AWS Lambda integration with Amazon EFS

Overview

This repository implements an AWS Lambda function that connects to an Amazon EFS access point.

Initialize

Copy the etc/environment.template file to etc/environment.sh and initialize the following variables: PROFILE, S3BUCKET, P_VPCID as specified. Copy etc/params_efs.template to etc/params_efs.json and initialize the ParameterValue fields.

Deploy EFS

Run make efs.create initially or make efs.update if updating to deploy an EFS filesystem, mounts, and access points. Copy outputs from the stack to the following variables: O_SECURITY_GROUP_LAMBDA, O_EFS_FILESYSTEM_ARN, O_EFS_ACCESS_POINT_ARN.

Deploy the Lambda function

Run make lambda to deploy the Lambda function.

Test the Lambda function

Run make lambda.local to test the function locally using SAM local. Run make lambda.invoke.sync to invoke the function within your AWS account.

When executing locally, you will see something like the following:

{
  "envvar1": "tbd",
  "envvar2": "tbd",
  "filesystem_location": "/tmp",
  "ip_address": "1.2.3.4",
  "region": "us-east-1",
  "execution_env": "AWS_Lambda_java11"
}

When executing in your AWS account, you will see something like the following:

{
  "initialization_type": "on-demand",
  "envvar1": "tbd",
  "envvar2": "tbd",
  "filesystem_location": "/mnt/efs",
  "ip_address": "1.2.3.4",
  "region": "us-east-1",
  "execution_env": "AWS_Lambda_java11"
}
