Serverless Plugin: Random Gateway deploymentId

1. Overview
2. Installation & Setup
3. Example

Serverless

Now supports Serverless 3.x

Overview

When using serverless framework only to deploy your aws resources without having any lambda functions or triggers, the AWS Gateway deploymemt does not behave as expected. Any deployment to an existing stage will be ignored, since CloudFormation does not redeploy a stage if the DeploymentIdentifier has not changed.

The plugin parses the custom Cloudformation resources and adds a random id to the deployment-name and all references to it

See the examples folder for a full working example

Installation & Setup

Run npm install in your Serverless project.

$ npm install --save-dev serverless-random-gateway-deployment-id

Add the plugin to your serverless.yml file

plugins:
  - serverless-random-gateway-deployment-id

Example

The following example demonstrates a simple gateway deployment configuration. On every deploy the plugin will attach a random identifier to ApiGatewayDeployment

service:
  name: user-registration

provider:
  name: aws
  stage: dev
  region: eu-central-1
