I had an AppRunner instance with a custom domain that was stuck on "Pending
certificate DNS validation” as it was trying to validate the ACM certificates.
Turns out that the UI to copy and paste the DNS validation entries can lead
you astray.
The record names include the domain name already. So if you copy and paste
from the AppRunner console into Route 53 you will end up with the domain name
in the record twice.
Simply remove the domain before pasting. I chalk this up to a less-than-good
user interface on the AppRunner side.
