Azure App Service Workaround 500 custom domain Limit

Is there any way to work around the 500 custom domain limit? This is horrible for SAAS companies for obvious reasons.

Is there any way to tell the Azure app service to respond to *.domain.com like you can with IIS?

Is my only other option to put Application gateway infront of it and run it in Azure Container Services or K8s?

Thanks!

Solution

  • The solution to this is to setup a *.domain.com wildcard DNS CName record that points to your App Service address (you can do this with an A record instead if you want) and then add *.domain.com as a Custom Domain into the App Service.

    Then you can bind a wildcard *.domain.com Certificate to it and you're golden. No limit.
