Terraform not deploying api gateway stage

问题

I have been trying to create an API Gateway endpoint using terraform. Everything seems to be working except the last part of deploying a stage.

After I run terraform apply I go into the console and I find that the deployment has not happened. I need to manually click on Deploy Api in order to get it working.

Here's the terraform file for the api gateway.

The Graph has other resources which I have not provided in the tf file above. Its only the API GW that has issues. By the way, I am able to test the API from the console and it works fine. I am not able to execute it from my localbox or postman.

Any idea on what I am doing wrong?

回答1:

TF does not deploy the API, this link might help you: https://medium.com/coryodaniel/til-forcing-terraform-to-deploy-a-aws-api-gateway-deployment-ed36a9f60c1a

I've fixed mine by adding the variable deployed_at:

resource "aws_api_gateway_deployment" "api_ingest_deployment" {
  depends_on = ["aws_api_gateway_method.xxx",
                "aws_api_gateway_integration.yyy",
                "aws_api_gateway_integration.zzz",
                "aws_api_gateway_integration.www",
  ]
  rest_api_id = "${aws_api_gateway_rest_api.foo.id}"
  stage_name = "${var.environment}"

  variables {
    deployed_at = "${timestamp()}"
  }
}

the downside is that if done this way it will always deploy, even if there's no change

回答2:

Generally the code change is at lambda level. So you may interpolate lambda code version as a variable and add it in same module where you have api deployment. This way it will deploy only when lambda code changes.
