NOTE: "Last Update" is the date of the latest DockerHub build.

This container is a super small (~5MB compressed pull, and only ~9MB when extracted) FULL version of ISC BIND9.

It is ideal for an extremely secure and fast master (authoritative server), slave, recursive server/resolver, RPZ "dns firewall", or just about any other purpose you can use bind for.

This container will always be up to date on the latest stable+patched version, usually within 24 hours of it being available in Alpine. In fact, most of the BIND vulnerabilities so far have been reported by me to the Alpine developers.

This container contains everything needed in terms of configuration to run as an authoritative server or a recursive resolver/forwarding cacher.

However, the default config permits queries and recursion only from 127.0.0.1 - which will not be too useful :) But the assumption is that you will override /etc/bind with your configs, and /var/cache/bind with your zones.

This container assumes you have a "/DATA" folder with with your container specific data. (You can change that folder, sub-folders, and file points as needed, but make sure you update the "-v" mounts for the run.)

Specifically, you need to have these directories/paths:

1.) [ *REQUIRED* ]
In your "/DATA/etc/bind" directory, a file "named.conf", which acts as an entry point to your configs
Take a look at the default config, and the example configs provided

2.) [ *REQUIRED* ]
A "/DATA/var/cache/bind" directory for all of the master or slave zones. If it's for slave zones, it will populate automatically and you can leave it blank.

This is just to test it out - by default only allows queries from itself (127.0.0.1) -- pretty useless for real world usage

docker run --name=dns-test
-it -d \
--dns=8.8.8.8 --dns=8.8.4.4 \
-p 53:53/udp -p 53:53 \
ventz/bind

Edit: named.conf.local with your forward zone at least and create the file in /var/cache/bind/$yourdomain.tld

docker run --name=dns-master
-it -d \
--dns=8.8.8.8 --dns=8.8.4.4 \
-p 53:53/udp -p 53:53 \
-v /DATA/etc/bind:/etc/bind \
-v /DATA/var/cache/bind:/var/cache/bind \
ventz/bind

Edit: named.conf.options -> change the "allow-recursion" and "allow-query" with your subnets

docker run --name=dns-resolver
-it -d \
--dns=8.8.8.8 --dns=8.8.4.4 \
-p 53:53/udp -p 53:53 \
-v /DATA/etc/bind:/etc/bind \
-v /DATA/var/cache/bind:/var/cache/bind \
ventz/bind

Additional options may be passed to the bind daemon via the OPTIONS argument, provided as: `docker run --env OPTIONS='...'
