LocalStack Demo: ELB Application Load Balancers

Simple demo application illustrating ELBv2 Application Load Balancers using LocalStack, deployed via the Serverless framework.

Prerequisites

  • LocalStack
  • Docker
  • Node.js / npm
  • make

Installing

To install the dependencies:

make install

Running

Make sure that LocalStack is started:

LOCALSTACK_AUTH_TOKEN=... DEBUG=1 localstack start

Deploy the app locally and run an ELB Lambda test invocation:

make run

You should see some output with the deployment logs of the Serverless application, and finally two successful invocations of the ELB endpoints /hello1 and /hello2:

> sls deploy --stage local
...
Serverless app successfully deployed. Now trying to invoke the Lambda functions via ELB endpoint.

Invoking endpoint 1: http://lb-test-1.elb.localhost.localstack.cloud:4566/hello1
"Hello 1"
Invoking endpoint 2: http://lb-test-1.elb.localhost.localstack.cloud:4566/hello2
