ViewsTerraform: How to create a api gateway POST method at root?
I am trying to create POST method using terraform at the root api gateway URL such as https://somehash.execute-api.us-east-1.amazonaws.com/dev which would include the stage. Here is part of the terraform plan of concern:
resource "aws_api_gateway_rest_api" "api" {
name = "submit-dev-gateway-api"
}
resource "aws_api_gateway_resource" "resource" {
rest_api_id = "${aws_api_gateway_rest_api.api.id}"
parent_id = "${aws_api_gateway_rest_api.api.root_resource_id}"
path_part = "submit"
}
resource "aws_api_gateway_method" "post_form" {
rest_api_id = "${aws_api_gateway_rest_api.api.id}"
resource_id = "${aws_api_gateway_resource.resource.id}"
http_method = "POST"
authorization = "NONE"
}
...
I tried changing the path_part to "/" but it did not work. I could not create a aws_api_gateway_method resource without aws_api_gateway_resource. I can create a POST at root manually without terraform which looks like this:
When I use the above terraform plan I get this:
How do I create POST at root with terraform?

The "root resource" is created automatically as part of creating an API Gateway REST API. In Terraform, the id of that root resource is exposed as the root_resource_id attribute of the REST API resource instance.
Because that resource is implicitly created as part of the API, we don't need a separate resource for it. Instead, we can just attach methods (and the other necessary downstream objects) directly to that existing root resource:
resource "aws_api_gateway_rest_api" "api" {
name = "submit-dev-gateway-api"
}
resource "aws_api_gateway_method" "post_form" {
rest_api_id = aws_api_gateway_rest_api.api.id
resource_id = aws_api_gateway_rest_api.api.root_resource_id
http_method = "POST"
authorization = "NONE"
}
