λ S3 to SFTP

Send an S3 file, whenever it is uploaded, to a remote server using SFTP

Warning: This repository is not under development or maintenance anymore, I strongly recommend using the yunojuno's fork instead

Deployment

1. If you are using a private key to connect to SFTP, edit main.py and put its value inside the PRIVATE_KEY var
2. make package
3. Upload package.zip to AWS Lambda (on console or command line)

Configuration in AWS Lambda

• Select Python 2.7 as the runtime environment.
• In AWS Lambda, you can define a trigger. Select S3 and then PUT. you can limit the triggers to a particular folder there.
• Set the handler name to "main.lambda_handler"
• Make sure you give Lambda permission to read from S3

Supported Events

• S3 PUT

Function Environment Vars

Caveats

This function does not replicates the S3 directory structure, it just copies every file uploaded to S3 to the SSH_DIR in the SSH_HOST.
