variable

Variables are module-level objects that essentially act as parameters for the module. When running Powerpipe, you can pass values on the command line, from a .ppvars file, or from environment variables, and you will be prompted for any variables that have no values.

You can reference variable values as var.<NAME>

Example Usage

variable "instance_state" {
  type    = string
  default = "stopped" 
}

query "instances_in_state" {
  sql = "select instance_id, instance_state from aws_ec2_instance where instance_state = $1;" 

  param "find_state" {
    default = var.instance_state
  } 
}
