Install

npm install serverless-ssm-parameters

Usage

Add the plugin to your serverless yml:

plugins
  - serverless-ssm-parameters

Create a new parameter

sls param_add

In the AWS Systems Manager Console:

Usage in your serverless.yml

As an example, serverless lets you prefix with ssm: to pull values from your SSM parameters. Here is an example with the ~true suffix. this means a SecureString.

~split is a comma separated StringList

environment:
  SECRET_TOKEN: ${ssm:/${self:service}/TEST_SECURE_STRING~true}

Push local ssmparameters.json parameters to SSM

sls params_push

Pull SSM parameters to local ssmparameters.json

sls params_pull

Security Suggestion

Use the ssmparameters.json to stage your params, sls params_push them, and then delete the ssmparameters.json, or move it out of the repo folder.

Upgrading params from String to SecureString

After you sls params_pull, open your ssmparameters.json and append the ~true suffix to all the param names.

{
  "TEST_SECURE_STRING~true": "349uy78rt345uy789rt45ey89rt3459y80hr345t"
}

Now sls params_push to upgrade all your parameters to SecureString.

Don't forget to append ~true for any references to your newly secured parameters in any serverless yml files you have, like this:

environment:
  SECRET_TOKEN: ${ssm:/${self:service}/TEST_SECURE_STRING~true}
