Setup

A guide on how to build Python Packages for AWS Lambda Layers using Docker containers.

Limitations of Lambda Layers

There are a few limitations that you need to be aware of and this includes:

You can only use up to 5 layers per Lambda.
The size of all your layers unzipped cannot exceed 250mb.
Layers are mounted to the /opt directory in the function’s execution environment so be sure to Layer your functions properly if you are going to have more than one.

FWIW: I'm not the author of the content presented here (which is an outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.

Basic Git workflow

The Git workflow you will be using is as follows:

Fork the repository to your GitHub account.
Clone the project on your machine.

	#!/bin/bash

	[email protected]
	DOMAINS=example.com,www.example.com,foo.example.com,example.org.example.net,www.example.org,www.example.net

	git clone https://github.com/letsencrypt/letsencrypt
	cd letsencrypt/
	mkdir -p /var/lib/letsencrypt/global-webroot

	# Setup the global alias

	#!/usr/bin/env python

	import sys
	import boto3


	def get_paginated_results(product, action, key, credentials=None, args=None):
	args = {} if args is None else args
	return [y for sublist in [x[key] for x in boto3.client(product, ({} if credentials is None else credentials)).get_paginator(action).paginate(args)] for y in sublist]

	#!/bin/bash
	#
	# A script to create a daily mysqldump for crashplan

	# Defaults
	# Override them in /etc/default/mysqlbackupforcrashplan
	OUTPUTFILE=/var/local/full-backup.sql
	STATEFILE=/var/local/full-backup.sql.state
	CRONFILE=/etc/cron.d/mysqlbackupforcrashplan
	MYSQLDUMPBIN=/usr/bin/mysqldump

	for bucket in `cat list-of-s3-buckets.txt`; do
	aws s3api put-bucket-lifecycle \
	--bucket $bucket \
	--lifecycle-configuration '{"Rules":[{"ID":"cleanup","Status":"Enabled","Prefix":"","Expiration":{"Days":1}}]}';
	done

	for region in `aws ec2 describe-regions --query 'Regions[].RegionName' --output text`; do
	aws sns list-subscriptions --query "Subscriptions[?starts_with(Endpoint, 'arn:aws:sqs:')].[TopicArn, Endpoint]" --output text --region $region
	done
