yaml for pihole container on QNAP

I am trying to make the following docker-compose.yaml to run on my QNAP container station.

The following part is working, but after the "restart: unless-stopped" the mess begins.

version: '3'

services:
  pihole:
    container_name: pihole
    image: pihole/pihole:latest
    ports:
      - "65003:53/tcp"
      - "65002:53/udp"
      - "65001:67/udp"
      - "65000:80/tcp"
    environment:
      TZ: 'Berlin'
      WEBPASSWORD: 'password'
    # Volumes store your data between container upgrades
    volumes:
      - './etc-pihole/:/etc/pihole/'
      - './etc-dnsmasq.d/:/etc/dnsmasq.d/'
    # Recommended but not required (DHCP needs NET_ADMIN)
    #   https://github.com/pi-hole/docker-pi-hole#note-on-capabilities
    cap_add:
      - NET_ADMIN
    restart: unless-stopped
      qnet_dhcp:
    image: alpine
    command: ifconfig eth0
    networks:
      - qnet-dhcp
  qnet_static:
    image: alpine
    command: ifconfig eth0
    networks:
      qnet-static:
        ipv4_address: 192.168.178.2
networks:
  qnet-dhcp:
    driver: qnet
    ipam:
      driver: qnet
      options:
        iface: "eth0"
  qnet-static:
    driver: qnet
    ipam:
      driver: qnet
      options:
        iface: "eth0"
      config:
        - subnet: 192.168.178.0/24
          gateway: 192.168.178.1

I got the network information directly from QNAP https://qnap-dev.github.io/container-station-api/qnet.html and tried to verify it with http://www.yamllint.com/, but it does not work together. error line 24

notvalid

One of your service names is not correctly indented.

Additionally, you have provided an invalid configuration for ipam for the version 3 file. You can only provide options in version 2 according to the docs.

I will truncate the file for brevity.

# you need file version 2 in order to use options in ipam
# the file you copied it from is also using version 2
version: '2'

services:
  pihole:
    ...
  # this one (qnet_dhcp) is the name of another service. 
  # In your original code the indention is incorrect.
  # It should be aligned with the other services.
  qnet_dhcp:
    ...
  qnet_static:
    ...

networks:
  qnet-dhcp:
    ...
    ipam:
      ...
      # as mentioned above,
      # this is only valid in version 2
      options:
        ...
