alternate install instructions for AWS Lambda

Instead of spinning up an EC2 instances, I used the Amazon Linux docker image locally

docker run -it amazonlinux:latest /bin/bash

Then on the docker image at the bash-4.2# prompt:

curl -sL https://rpm.nodesource.com/setup_6.x | bash -
yum install -y gcc-c++ nodejs-6.10.3
mkdir /var/task && cd /var/task
npm install sharp

Back on the host (in a separate terminal window), I copied node_modules to my project directory. (182008de1f47 is the CONTAINER ID from docker ps):

docker cp 182008de1f47:/var/task/node_modules .

Maybe these could be alternate install instructions in the AWS Lambda section of docs/install.md?

Yes, https://github.com/awslabs/aws-sam-local even uses that docker-lambda image. It is on my list to look at as well.

I am having some issue with this while using typescript and webpack. I do the docker-npm install, and that seems to do it’s thing, but I still get this issue when deploying to AWS lambda.

It says; [684] external "sharp" 42 bytes {0} [built] and Serverless: Packing external modules: sharp@^0.20.5.

Perhaps serverless-webpack is changing the binary somehow?
