I have a compute engine with a simple page builder, on this server I can have several domains pointed to, currently I create a new SSL certificate with the domains I want, ex: example1.com, example2.com and etc... Then I access the load balancer and edit the frontend settings and add the new certificate that I generated. :

existing domains: example 1.com, example2.com new domain: example3.com

What I have to add when generating the ssl are the three example1.com, example2.com,example3.com

Is there another way to do this?

page for create certificate

current certificated

where I add new certificates or update

  • Google free certificates are mapped to only one domain so the answer is no. The other option is that you own a wildcard certificate but only will apply to subdomains of a single root domain. – Puteri Mar 04 '23 at 03:07
  • Add multiple certificates to the load balancer. Google HTTP Load Balancers support more than one certificate (purchased and Google managed). – John Hanley Mar 23 '23 at 22:05
  • @JohnHanley that's what I do, but it's very costly, and every time I add a new domain, I have to change the load balancer to use the new certificate, and that generates a minute of offline application, I don't know what I'm doing wrong. In the question there are the prints... – Alessandro Prudencio Mar 24 '23 at 18:24
  • What problem are you trying to solve? Do you mean that you want "instant" certificate deployment? I am not aware of a Google-managed service that can instantly deploy a certificate. There will be some downtime while the frontend reconfigures. You could use multiple load balancers pointing to the same backend. New domain/certificate, add a new load balancer. – John Hanley Mar 24 '23 at 19:00
  • @JohnHanley I can't add a new load balancer targeted to the same ip. Error: Invalid value for field 'resource.IPAddress': 'projects/teste-375613/global/addresses/ulink-load-balancer'. Specified IP address is in-use and would result in a conflict. – Alessandro Prudencio Jul 02 '23 at 02:33
  • @AlessandroPrudencio not enough details so that I understand what you are doing. Create a new question and let me know the link. – John Hanley Jul 02 '23 at 02:38
  • @JohnHanley I created it, follow the link https://stackoverflow.com/questions/76597250/how-to-have-multiple-certificates-for-a-loadbalancer – Alessandro Prudencio Jul 02 '23 at 03:01
