serverless-offline-ssm

This Serverless plugin allows you to develop offline while using AWS SSM parameters in your serverless.yml template. The plugin looks for environment variables which are fulfilled by SSM parameters at build time and substitutes them from a .env file when running locally with the serverless-offline plugin.

NOTE!!

Version 6.x only works with Serverless 3+. Version 5.X only works Serverless 1.69+, if you'd like to use this
plugin with Serverless <= 1.59 use version 4.1.2

Installation

First install the plugins using npm or yarn

``bash
npm install serverless-offline serverless-offline-ssm --save-dev

#or

yarn add -D serverless-offline serverless-offline-ssm
`

Then inside of your project's serverless.yml file add the following to the plugins section. Note it is important that serverless-offline-ssm is loaded before serverless-offline. This is important to ensure that we are setting the variables properly for serverless-offline before it needs them.

_NOTE:_ It is imperative that serverless-offline-ssm be the the first plugin listed in the plugins section of your serverless.yml file. Due to the load order of plugins, other plugins may interfere with the loading of your .env file.

`yaml
plugins:
- serverless-offline-ssm
- serverless-offline
`

Configuration

You can choose to use a .env file and/or define your variables in
serverless.yml. Variables within serverless-offline-ssm take precedence.
serverless-offline-ssm will always check if the section custom.serverless-offline-ssm
have any values, if not it will fallback to .env

$3

This plugin executes if the stage defined within the plugin options
or provider sections of your serverless.yaml are includes within the
stages property of the plugin configuration. If this condition has not been
met the plugin has no effect.

The stages property of the plugin configuration can be overridden with a
cli parameter --ssmOfflineStages which takes a comma separated list of
stages.

$3

Your .env file needs to contain only variable names without the ssm: prefix and ~(true|false|split) sulfix.

If you've defined ${ssm:lambda.LAMBDA_NAME.DB_DSN~true} in serverless.yml file your .env need to be like the example bellow:

`
lambda.LAMBDA_NAME.DB_DSN="VAR VALUE"
`

$3

`yaml
provider:
stage: offline
custom:
serverless-offline-ssm:
stages:
- offline
ssm:
'lambda.LAMBDA_NAME.DB_DSN': 'sample-value-goes-here'
'another.sample.value': '99 red baloons'
