us-east-1和us-east-2中的AWS API网关高可用性设置

Question

I want to setup API gateway services in two regions for HA. The primary is in east1. On health check failure it sould route to east 2.

Followed this article (below) to setup the same.

https://aws.amazon.com/blogs/compute/building-a-multi-region-serverless-application-with-amazon-api-gateway-and-aws-lambda/

What we did

1) setup my api services in both east 1 & east 2 2) both apis are created as regional(not cloud front) 3) created two certificates in each region with single custom domain name say api-ha-example.com. Mapped to with each of its reginal certificate(ACM) 4) The custom domains are created in each region 5) two cname records exsits now in R53 with same name "api-ha-example.com" and, value of each regional API end point. Show here.

  1)api-ha-example.com --->  https://xxxxx.execute-api.us-east-1.amazonaws.com/initdev ----> Primary
   2)api-ha-example.com --->  https://xxxxx.execute-api.us-east-2.amazonaws.com/initdev ----> secondary

Health check is set to 200 status for primary for now

The problem ----------- I am able to hit the indivisual API enpoints directly. But when i hit with the domain name https://api-ha-example.com/ I dont get anything. site cant be reached. ping test says, cant reolve the domain to server.Anything missing in my settings? Followed the steps as per blog

Anyone faced this issue?

Answer 1

You have configured this in DNS:

api-ha-example.com CNAME https://xxxxx.execute-api.us-east-1.amazonaws.com/initdev ;; primary
api-ha-example.com CNAME https://xxxxx.execute-api.us-east-2.amazonaws.com/initdev ;; secondary

DNS CNAME records are hostnames, only -- they have no support for either schemes or paths, so the https:// at the beginning and /initdev at the end of the CNAME records need to be removed.
