tf-api module

Module for the creating API Gateway by custom swagger API template

Check the interpolation rules

Here is an important note for the Swagger extension like $ref, it should be $$ref Because:

You can escape interpolation with double dollar signs: $${foo} will be rendered as a literal ${foo}.

With TF resource

data "template_file" "swagger" {
  template = "${file("files/swagger.yaml")}"

  vars {
    name              = "${var.name}"
    env               = "${var.env}"
    dns_name          = "${var.domain}"
    client_name       = ${var.client_name}
    application_name  = ${var.application_name}
  }
}

Example of Swagger file:

---
swagger: "2.0"
info:
  version: "2018-10-21T18:37:10Z"
  title: "${client_name}-${application_name}"
host: "${dns_name}"
basePath: "${stage}"
schemes:
- "https"
paths:
  /:
    get:
      consumes:
      - "application/json"
      produces:
