Not allowed to configure Weight parameter for CNAME created by CloudMap

[fcappi]

Describe the bug

1. Create CloudMap namespace, service and service instances. Make sure you choose option to allow service discovery via DNS queries and to register instances as CNAME
2. Go to route53 and try to update weight property of CNAME records, so you can control how much traffic goes to each instance.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

You should be able to update weight property for CNAMEs created by cloud map

Current Behavior

Update fails with message:

Error occurred
Please try again later.
(The resource hostedzone/**** can only be managed through AWS Cloud Map (arn:aws:servicediscovery:eu-west-2::namespace/ns-))

And there is no option to configure weight on cloud map

Reproduction Steps

1. Create CloudMap namespace, service and service instances. Make sure you choose option to allow service discovery via DNS queries and to register instances as CNAME
2. Go to route53 and try to update weight property of CNAME records, so you can control how much traffic goes to each instance.

Possible Solution

Add new attribute on service instance to configure weight for CNAME (Example: AWS_CNAME_WEIGHT)

Hi @fcappi

Route 53 blocking direct modification of records in a CloudMap-managed hosted zone appears to be an expected service behavior.

This feature request needs to be implemented by the CloudMap service team. I will submit an internal request to track this with the service team on your behalf.

That said, if you have access to AWS Support, I would encourage you to also submit a case there.
