yaml for pihole container on QNAP - docker-compose

Question

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.

Answer 1

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:
...
