i am using gcp and dynamically creating instances. the ip is already known to me and i can set it in a config file during startup script.

can there be an option so the ipsource doesn't lookup rather reads from a static file?

Sure, IP source modules can return the IP from anywhere. Feel free to implement one and register it on the Caddy website.

To clarify, you can write your own IP source plugin:

https://caddyserver.com/docs/json/apps/dynamic_dns/ip_sources/

It just needs to be a Caddy module under the dynamic_dns.ip_sources namespace which implements this interface: https://github.com/mholt/caddy-dynamicdns/blob/master/ipsource.go#L24-L26

See https://caddyserver.com/docs/extending-caddy for an explainer on how to write plugins for Caddy.
