Fix docker DNS not working on Linux hosts
View fix-docker-dns.md

Docker DNS issues on systemd distros

(Hopefully) fix Docker DNS issues with systemd distros, e.g. ping: bad address 'google.com', Temporary failure resolving ..., EAI_AGAIN (tested on Arch).

Checklist

  1. Host DNS is correct (/etc/resolv.conf) and does not contain any invalid nameservers
  2. Ensure DNS resolves correctly (dig google.com @ipaddress.from.resolvconf.here)
  3. Ensure Docker container has same config as host docker run -it <your-image> cat /etc/resolv.conf
