How to customize rancher dns' answers.yml

I want to add one A Record to the internal rancher dns.

How can I achieve this?

Thanks in advance.

You can use an alias or external alias to do that however if your alias has the name ‘myrecordname’ and is deployed in a stack ‘mystack’ the service will have a A record internally available in the Rancher environment of ‘myrecordname.mystack’ or simply ‘myrecordname’ in its own stack. If you need the same simple ‘myrecordname’ to be available in all stacks I think you will have to deploy an alias in each one.
