serverless-localstack

Serverless Plugin to support running against Atlassian Labs 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)

If you'd like to install serverless-localstack via source:

Clone the repository

  git clone https://github.com/temyers/serverless-localstack

Install the plugin

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

cd project-path/
mkdir .serverless_plugins
ln -s /absolute/path/to/plugin .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.

Configuring endpoints via serverless.yml

service: myService

plugins:
  - serverless-plugin-localstack

custom:
  localstack:
    host: http://localhost
    endpoints:

      SQS: http://localhost:4576
      Lambda: http://localhost:4574
      Kinesis: http://localhost:4568

Configuring endpoints via JSON

service: myService

plugins:
  - serverless-plugin-localstack

custom:
