I am in the process of trying to map custom domains to my app engine app. Basically what we are trying to do is white label our current service and allow external domains such as www.myexternaldomain.com to point to mydomain.com and serve the same content as mydomain.com. I recently learned that app engine has a 20 domain limit but since I am not actually creating sub domains for external domains and I will always be serving content from mydomain.com will this be a problem? If not how would I do this?
So just to make this a little clearer, I want to do something like this:
external-domain-1.com (Serves) -> mydomain.com
external-domain-2.com (Serves) -> mydomain.com
We should be able to figure out the domain thats calling our website and change things such as logo, images etc. Am I correct? If not does anyone have any ideas on how we can still do this within the GCP environment without having to do a major shift, given we already have this set up on App Engine? I was also thinking that we may be able to use a wildcard subdomain to handle the external domains such as
external-domain-1.com (Serves) -> *.mydomain.com
