Hey,

did you map the port([1] or [2]) in your docker container correctly? From what network do you want it to be reachable? The docker network 172.17.0.1 you mentioned is usually docker internal, and mostly used for communication between containers. If docker port exposure is setup correctly, the apache service is reachable on the IP of your VM/CT(the debian machine on 192.168.x.x you mention). So, if you now want it to be reachable from the internet you have to setup port forwarding, something like [3], on your static IP that PVE is on(to the VM/CT apache is running on).
