Introduction

Dockerfile to create a Docker container image for ARM running the BIND DNS server.

BIND is open source software that implements the Domain Name System (DNS) protocols for the Internet. It is a reference implementation of those protocols, but it is also production-grade software, suitable for use in high-volume and high-reliability applications.

Issues

Before reporting your issue please try updating Docker to the latest version and check if it resolves the issue. Refer to the Docker installation guide for instructions.

SELinux users may need to update the security context of the host mountpoint so that it plays nicely with Docker:

mkdir -p /srv/docker/bind
chcon -Rt svirt_sandbox_file_t /srv/docker/bind

If SELinux still gets in the way, you can try disabling it using the command setenforce 0 to see if it resolves the issue.

If the above recommendations do not help then report your issue along with the following information:

• Output of the docker version and docker info commands
• The docker run command or docker-compose.yml used to start the image. Mask out the sensitive bits.
• Please state if you are using Boot2Docker, VirtualBox, etc.

Getting started

Installation

Automated builds of the image are available on Dockerhub and is the recommended method of installation.

docker pull benpiper/docker-bind:latest

Alternatively you can build the image yourself.

docker build -t benpiper/docker-bind github.com/benpiper/docker-bind

Quickstart

Start BIND using:

docker run --name dns1 -d --restart=always \
  --publish 53:53/tcp --publish 53:53/udp \
  benpiper/docker-bind:latest

This will load BIND with a sample configuration and zone (siliconharbor.io). If you want to start with a clean slate, see the following Persistence section.

Persistence

For BIND to preserve its state across container deletion you can mount a volume at /data by adding the following flags to the docker run command:

--volume /srv/docker/bind:/data

Alternatively, you can use the sample docker-compose.yml file to start the container using Docker Compose

Maintenance

Shell Access

For debugging and maintenance purposes you may want access the containers shell. If you are using Docker version 1.3.0 or higher you can access a running containers shell by starting bash using docker exec:

docker exec -it benpiper/docker-bind bash
