# Installation Notes Valheim app does not support having different port numbers for `port` and `targetPort`. Setting `port` will set the same port number to `targetPort` and it's Environmental Variable. e.g `STATUS_HTTP_PORT`, `SUPERVISOR_HTTP_PORT`, `SERVER_PORT` Also, services named `valheim1`, `valheim2`, `valheim3`, should be continuous port numbers. eg 2456, 2457, 2458. You can't skip a number!
