    $ terraform-docs variables.tf outputs.tf

    # Generate a JSON of inputs and outputs
    $ terraform-docs json ./my-module

    # Generate markdown tables of inputs and outputs

Given a simple module at ./_example:

/**
 * This module has a variable and an output.  This text here will be output before any inputs or outputs!
 */

variable "subnet_ids" {
  description = "a comma-separated list of subnet IDs"
}

// The VPC ID.
output "vpc_id" {
  value = "vpc-5c1f55fd"
}

To view docs:

$ terraform-docs _example

To output JSON docs:

$ terraform-docs json _example
{
  "Comment": "This module has a variable and an output.  This text here will be output before any inputs or outputs!\n",
  "Inputs": [
    {
      "Name": "subnet_ids",
      "Description": "a comma-separated list of subnet IDs",
      "Default": ""
    }
  ],
  "Outputs": [
    {
      "Name": "vpc_id",
      "Description": "The VPC ID.\n"
    }
  ]
}

To output markdown docs:

$ terraform-docs md _example
