I have been using the "Custom domains" integration in Cloud Run to set up the load balancer with custom domains. This has worked well, up until I tried to deploy my 16th app to Cloud Run. I then received an error stating "At most 15 SSL certificates" (see attached).
Why at most 15 SSL certificates?
Why did I not receive any warnings when I approached the limit (e.g., at 13 SSL certificates, receive a warning when adding the 14th)?
It appears that I cannot just use a managed certificate for a wildcard domain:
ERROR: (gcloud.compute.ssl-certificates.create) Could not fetch resource:
- Invalid value for field 'resource.managed.domains[0]': '*.my_custom_domain.org'. Wildcard domains not supported.
...so do I now have to create managed ssl certificates for each individual app's custom domain?
