I’ve just installed chef-server on an EC2 instance, and downloaded the starter-kit from chef-manage. Unfortunately, I can’t connect. The chef_server_url value contains the server’s private dns instead of the public one. I can manually update my knife.rb file with the public dns, but then I run into a certificate error because the server presents certificates for the private dns instead of the public one. How can I tell chef-server to use its public address?
