AWS Lambda Layer Docker image

Docker image which allows user to create a zip file with all Python dependencies for a custom AWS Lambda function (by default with influxdb-client). This should be within the limit of 10MB per single browser upload (~3,5MB with just the influxdb-client-python library). If the zip archive is uploaded to a custom Lambda Layer then user is able to keep using the Console IDE for editing main Lambda function.

Build image:

docker build -t lambdalayer:latest .

Create container:

docker create --name lambdalayer lambdalayer:latest

Copy zip from container:

docker cp lambdalayer:/install/python.zip .

Upload zip to AWS Lambda

Use AWS CLI or AWS Console to create and upload archive to a custom Lambda Layer. Then import those dependencies in lambda function as usual.
