Cloud Run suggests to map “claraom.io” to via A and AAAA records to 8 different IPs. That works absolutely fine so long as the records are “DNS only” and I use full SSL/TLS encryption mode.
The problem is with the subdomains ([email protected] and [email protected]). Cloud run suggests to map those via CNAME to “ghs.googlehosted.com.”. Setting that up doesn’t work, the subdomains set up that way don’t seem to resolve. But when I set up the subdomains using A and AAAA records by pointing them to the root domains IPs it all works fine, but that needs setting up 8 records for each subdomain!
Can someone help me understand how to correctly configure the DNS using CNAME to point to Cloud Run for my subdomains?
