Updating my APIGW deployment with Terraform?

Question

I understand the title looks weird, but I'll do my best to explain it. Right now, my APIGW deployment looks like this:

resource "aws_api_gateway_rest_api" "apig" {
  body = "${file("../json-resolved/swagger.json")}"
  name = "apig"
}

resource "aws_api_gateway_deployment" "apig_deployment" {
  rest_api_id = aws_api_gateway_rest_api.apig.id

  triggers = {
    redeployment = sha1(jsonencode(aws_api_gateway_rest_api.apig.body))
  }

  lifecycle {
    create_before_destroy = true
  }
}

Now, the API itself has some variables, for example, the AWS Function URI: region, account_id and stage variable (environment). The way I did that before was by using:

aws apigateway put-rest-api --rest-api-id $Gateway_ID --mode overwrite --body fileb://$Build_SourcesDirectory/json-resolved/swagger.json

aws apigateway create-deployment --rest-api-id $Gateway_ID --stage-name $ENV --variables environment=$ENV

How do I do the same with Terraform?

Answer 1

Create an aws_api_gateway_stage in Terraform. Define the environment variables in the aws_api_gateway_stage. See the first example in the aws_api_gateway_deployment documentation, which includes an aws_api_gateway_stage.
