さくらのVPSで動かしてたイメージを自宅サーバへ移動したので，宅内からでも名前で引けるようにDNSサーバを立てる．
こちらのイメージでdnsmasqをコンテナで動かす．

docker-compose.yml

version: '2'
services:
  dnsmasq:
    restart: always
    image: andyshinn/dnsmasq
    container_name: dnsmasq
    ports:
      - "53:53/udp"
      - "53:53/tcp"
    extra_hosts:
      - "hoge.tac42.net:192.168.11.200"
      - "test.tac42.net:192.168.11.200"
    cap_add:
      - NET_ADMIN

extra_hosts に名前解決したいホスト名とIPアドレスを書くだけ．

$ sudo systemctl stop systemd-resolved.service
$ sudo systemctl disable systemd-resolved.service
$ sudo docker-compose up -d
