### ISC BIND9 Container (Stable: 9.11.2_xx) built on top of Alpine
|
|
### Last update: 2-12-18 (major new update!)
|
|
|
|
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.
|
|
|
|
# Security - always on the latest stable BIND release!
|
|
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.

# How to deploy a Bind (DNS) server?
|
|
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/bind``` with your zones.
|
|
|
|
# Required "DATA" directory - for configs and zone data:
|
|
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/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.
|
|
```

# How to run a BIND ("named") Docker Container?
|
|
|
|
```
|
|
# Default Example
|
|
# 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
|
|
```
|
|
|
|
```
|
|
# Customer Override Example for Authoritative Master
|
|
# Edit: named.conf.local with your forward zone at least
|
|
# and create the file in /var/named/$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/bind:/var/bind \
|
|
ventz/bind
|
|
```
|
|
|
|
```
|
|
# Custom Override Example for Recursive Resolver/Cacher:
|
|
# 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 \
