I have one load balancer on the GCP. my project uses multi-domain and it is possible that add domains on after. when I create a certificate with the google-managed certificate, I can't edit the certificate and add a domain. I know I can remove the certificate and create a new certificate. but not good because domains will not be certified for a while.
Do I have to get a certificate from somewhere else? Is it possible to get a certificate that I can add to that domain later without changing the public key and private key? What is your suggestion?
