I'm trying to use OpenWRT as a Docker host to run pihole attached the LAN network of OpenWRT. I have done this before with an Ubuntu host where OpenWRT was a virtualbox vm and pihole is a docker container, both were running on the Ubuntu host connected to bridged Ethernet network. I had to do the macvlan workaround so that the Ubuntu Host and the OpenWRT VM could ping the pihole LAN IP.
With the new awesome release 21.02 (thanks to everyone!), I thought of moving the pihole container into OpenWRT as it supports Docker. However when I'm trying the basic macvlan setup like below, I'm getting an error when starting the container.
... networks: internal: lan: name: lan driver: macvlan driver_opts: parent: eth2 #LAN interface which is currently not a bridged LAN in OpenWRT ipam: config: - subnet: 192.168.1.0/24 gateway: 192.168.1.1
root@OpenWrt:~/docker-data# docker-compose -f docker-compose.yml up pihole Building with native build. Learn about native build in Compose here: https://docs.docker.com/go/compose-native-build/ Starting pihole ... error ERROR: for pihole Cannot start service pihole: failed to create the macvlan port: operation not supported ERROR: for pihole Cannot start service pihole: failed to create the macvlan port: operation not supported ERROR: Encountered errors while bringing up the project.
I'm looking for a way for making that work, running pihole inside of OpenWRT. Is it maybe possible with lxc or ujail instead?
