Usage

During deployment

Add any params you want published to SSM to your serverless.yaml custom section. You can use source to give the name of a Cloud Formation Output value you want published to SSM. Ssm publish compares existing values and will only write if no value exists/ the value has changed.

resources:
  Outputs:
    ExampleStaticValue:
      Value: example-static-value
      Export:
        Name: 'service-staticValue'
      Description: initial description

custom:
  secretToken: ${opt:secretToken}

  someConfiguration:
    foo: bar
    baz: 1
    more:
      - stuff
      - here

  ssmPublish:
    enabled: true                                # Needs to be set to true
    params:
      # simple usage, `value` is a string
      - path: /global/tokens/secretToken
        value: ${self:custom.secretToken}
        description: Super Secret Token          # description is optional
        secure: true                             # defaults to true

      # `value` can be an object; it is serialized to YAML before upload to SSM
      - path: /global/tokens/secretToken
        value: ${self:custom.someConfiguration}

      # `source` can be used as an alternative to `value`. If `source` is given, ssmPublish will retrieve
      # the matching value from the service's CloudFormation Stack Outputs
      - path: /service/config/storageBucket
        source: ExampleStaticValue
        secure: false

From the CLI

You can also call the plugin directly in order to update SSM params without running deployment/packaging.
