Docker - DNS Server

I propose to create a Docker Bind9 Image using base Docker Alpine Linux images, with S6 init system.

Work in progress

The main router must be set to forward packets! The ability to forward packets must be set / allowed, edit or add the following parameters in sudo vim /etc/sysctl.conf:

• net.ipv4.ip_forward = 1
• net.ipv4.conf.all.proxy_arp = 1
• sudo sysctl net.ipv6.conf.all.forwarding=1 similar for ipv6

After applying these changes reboot or apply setting using sudo sysctl -p /etc/sysctl.conf

• /usr/sbin/named -f -4 to start the isc-bind9 application called named,
  • -f to run in foreground
  • -4 to run ipv4 only
• rndc stop to stop named - need to implement this in S6
• rndc reload to reload the named configuration files
• named-checkconf /etc/bind/named.conf
• named-checkzone kptree.net /etc/bind/db.kptree.net
• named-checkzone 1.168.192.in-addr.arpa /etc/bind/db.1.168.192
