    // "http" and "state" seems to uniquely identify an interesting HTTP port on each service
    PortInfo port = service.getPorts().stream().filter(portInfo -> portInfo.getTags().stream().collect(Collectors.toSet()).containsAll(Stream.of("http", "state").collect(Collectors.toSet()))).findFirst().orElseThrow(() -> new NotFoundException("Failed to find HTTP state port"));
