  4. Configure AWS CLI aws configure (enter access/secret key, region and 'json' as output format)
  5. Pull local lambda java docker environment. docker pull lambci/lambda:java8 github

local Nodejs

Run a docker container and mount the code through as a volume:

docker run --rm -v "$PWD"/task:/var/task lambci/lambda:nodejs6.10

local Java

Simple String-length count handler

Make package

mvn package

Run a docker container with parameters:

Testing with SAM (nodejs)

Use SAM to test locally.

In the correct directory, start SAM

cd products && sam local start-api

Execute various requests

curl http://localhost:3000/products
curl -XPOST http://localhost:3000/products
curl -XDELETE http://localhost:3000/products/1
curl -XPUT http://localhost:3000/products/1
curl -XPATCH http://localhost:3000/products

Java - with S3 Event

Requires the protobuf-test artifact to be installed locally.

Uses ./template.yaml to define function / behaviour (the SAM spec)

mvn package
sam local generate-event s3 --bucket testbucket  --key testkey > s3event.json
sam local invoke  S3Handler -e s3event.json
