serverless-localstack

Serverless Plugin to support running against Localstack.

This plugin allows any requests to AWS to be redirected to a running Localstack instance.

WARNING: This plugin is very much WIP

Pre-requisites:

• Localstack

Installation

The easiest way to get started is to install via npm.

npm install -g serverless
npm install -g serverless-localstack

Installation (without npm)

In order for the plugin to be recognized it must first be enabled via the .serverless_plugins directory.

cd project-path/
npm install --save bluebird
npm install --save aws-sdk
mkdir .serverless_plugins
ln -s /<PATH TO THE PLUGIN DIRECTORY>/src/index.js .serverless_plugins/serverless-plugin-localstack

Configuring

There are two ways to configure the plugin, via a JSON file or via serverless.yml. There are two supported methods for configuring the endpoints, globally via the "host" property, or individually. These properties may be mixed, allowing for global override support while also override specific endpoints.

A "host" or individual endpoints must be configured or this plugin will be deactivated.
