Amazon Parameter Store Data Source

The Parameter Store data source provides information about a parameter in SSM.

Note: Data sources is a feature exclusively available to HCL2 templates.

Basic examples of usage:

data "amazon-parameterstore" "basic-example" {
  name = "packer_test_parameter"
  with_decryption = false
}

# usage example of the data source output
locals {
  value   = data.amazon-parameterstore.basic-example.value
  version = data.amazon-parameterstore.basic-example.version
  arn     = data.amazon-parameterstore.basic-example.arn
}

Configuration Reference

Required

name (string) - The name of the parameter you want to query.

Optional

with_decryption (bool) - Return decrypted values for secure string parameters. This flag is ignored for String and StringList parameter types.

Output Data

value (string) - The parameter value.
version (string) - The parameter version.
arn (string) - The Amazon Resource Name (ARN) of the parameter.

Authentication

The Amazon Data Sources authentication works just like for the Amazon Builders. Both have the same authentication options, and you can refer to the Amazon Builders authentication to learn the options to authenticate for data sources.

Note: A data source will start and execute in your own authentication session. The authentication in the data source doesn't relate with the authentication on Amazon Builders.

Basic example of an Amazon data source authentication using assume_role:

data "amazon-parameterstore" "basic-example" {
  name = "packer_test_parameter"
  with_decryption = false

  assume_role {
      role_arn     = "arn:aws:iam::ACCOUNT_ID:role/ROLE_NAME"
      session_name = "SESSION_NAME"
      external_id  = "EXTERNAL_ID"
  }
}
