your setup is the closes i want to get for not wanting to touch my router as my dhcp server. but i get this error from running this. Any tips?

root@ubuntu:/home/ubuntu# docker run --net=host --cap-add=NET_ADMIN -e DHCP_RANGE_START=192.168.1.1 samdbmg/dhcp-netboot.xyz

Are you running this on a Raspberry Pi or something? That'll be because I haven't built this for the ARM architecture I'm afraid.

For now, if you clone the repo and do docker build -t local/dhcp-netboot.xyz ., then change your command above to docker run --net=host --cap-add=NET_ADMIN -e DHCP_RANGE_START=192.168.1.1 local/dhcp-netboot.xyz that should work, although I don't actually have an ARM system I can test that on.

I better go off and learn about Docker multi-arch manifests to see if I can make CI do that, but it might be a while before I get to it

yes i am trying to run on a raspberry pi 4. But i thought i address that via --platform linux/amd64 command. but im not the good with docker and i will try your suggestion after i get some free time. I will let you know if it works. Thanks Sam for the reply.
