Server Alias¶ Allows the definition of one or more aliases in the server definition of the NGINX configuration using the annotation nginx.ingress.kubernetes.io/server-alias: "<alias 1>,<alias 2>". This will create a server with the same configuration, but adding new values to the server_name directive.

Note

A server-alias name cannot conflict with the hostname of an existing server. If it does, the server-alias annotation will be ignored. If a server-alias is created and later a new server with the same hostname is created, the new server configuration will take place over the alias configuration.

For more information please see the server_name documentation.
