» aws_ssm_parameter

Provides an SSM Parameter resource.

» Example Usage

To store a basic string parameter:

resource "aws_ssm_parameter" "foo" {
  name  = "foo"
  type  = "String"
  value = "bar"
}

To store an encrypted string using the default SSM KMS key:

resource "aws_db_instance" "default" {
  allocated_storage    = 10
  storage_type         = "gp2"
  engine               = "mysql"
  engine_version       = "5.7.16"
  instance_class       = "db.t2.micro"
  name                 = "mydb"
  username             = "foo"
  password             = "${var.database_master_password}"
  db_subnet_group_name = "my_database_subnet_group"
  parameter_group_name = "default.mysql5.7"
}

resource "aws_ssm_parameter" "secret" {
  name        = "${var.environment}/database/password/master"
  description = "The parameter description"
  type        = "SecureString"
  value       = "${var.database_master_password}"

  tags {
    environment = "${var.environment}"
  }
}

» Argument Reference

The following arguments are supported:

  • name - (Required) The name of the parameter.

  • value - (Required) The value of the parameter.
  • description - (Optional) The description of the parameter.
  • key_id - (Optional) The KMS key id or arn for encrypting a SecureString.
  • overwrite - (Optional) Overwrite an existing parameter. If not specified, will default to false if the resource has not been created by terraform to avoid overwrite of existing resource and will default to true otherwise (terraform lifecycle rules should then be used to manage the update behavior).
  • allowed_pattern - (Optional) A regular expression used to validate the parameter value.
  • tags - (Optional) A mapping of tags to assign to the object.
