如何为 AWS 负载均衡器配置 Google Cloud DNS

Question

I have an AWS load balancer. AWS assigns a DNA name like: data-vm-190.eu-west-1.elb.amazonaws.com

When I try to create a DNS CNAME record in Google Cloud, I get this error: "Record data must be in the format server-1.example.com"

How can I get past this?

Answer 1

The solution is to append a dot ( . ) to the record name.

Adding a dot (period or . ) at the end of a domain name declares a fully qualified domain name. Without the trailing dot, some DNS servers will treat the name as relative to the zone name.

In the hierarchy of the domain name system, the root servers are named . . The domain com is a child of the root servers. The fully qualified name for com is com. . Popular usage dropped the trailing root servers (dropped the . ) but DNS still treats that character as important.
