Hi everyone,

I own a homeserver running multiple services set up in individual docker compose projects. One of them is dnsmasq + pi-hole. Pi-hole is exposed on the host’s 53 port and uses dnsmasq as upstream. The host’s /etc/resolv.conf points to 127.0.0.1 to use pi-hole. Other containers from other compose projects on the same machine indirectly use pi-hole as well, as they use docker’s embedded DNS which forwards to the host.

Everything had worked fine for weeks before I ran into an issue after unattended-upgrades updated docker. After the upgrade, systemd attempted to restart the docker service. From the logs, it seems that the containers had a hard time honoring the SIGTERM. They started to complain about failing to reach the DNS server. At least that’s my understanding from journalctl -u docker. Here’s a (long) excerpt that shows:

  • containers failing to stop gracefully
  • stale processes after docker forcibly shut them down
  • repeated errors “stream copy error: reading from a closed fifo” afterwards that I am wondering what they mean

I ssh’ed into the server and noticed that the pi-hole & dnsmasq containers were not running. I ran docker compose up -d in all projects, starting with the DNS one and it went back to normal.

My question is: how bad of an idea is this to run a DNS in docker and use it for the host and other containers? Maybe I just had back luck but I can’t help thinking this setup creates some sort of circular dependency between the host, docker and the containers.

If anyone has experience with a similar setup, I’d be curious to hear their opinion on the issue I ran into.

Thanks!
