daaru/devdns repository overview

Run a local DNS container with auto-restart (--restart always) named "dns" (--name dns). It automatically load itself into /etc/resolv.conf host system machine (-v /etc/resolv.conf:/tmp/resolv.conf) and resolve Docker (-v /var/run/docker.sock:/var/run/docker.sock:ro) container's IPs with its name on .docker (-e DNS_DOMAIN=docker) domain name. Any container inside any network (-e NETWORK=auto) can be reached from your system using your browser, MySQL clients, FTP clients, SSH and any other kind of network protocol.

Run this on-liner command to execute DNS container:

docker run -d -v /var/run/docker.sock:/var/run/docker.sock:ro \ 
  -v /etc/resolv.conf:/tmp/resolv.conf \
  -e NETWORK=auto \
  -e DNS_DOMAIN=docker \
  --name dns --restart always \
  daaru/devdns:latest

NOTE: When you go offline or change WiFi network file are rewritten by system and you'll lose connection to DNS. Simply reload this container to fix this issue.
