Description

This docker image provides a bind service based on Alpine Linux.

If you like to use this image, please use a specific version tag like v1.0.0 or the branches latest, stable. The other branches are only temporary and will be deleted after the merge into the other branches.

There are two options to start your Bind container.

Docker Run

Use this docker command to run the bind container.

docker run -d --name bind --publish 53:53/udp \
-v /bindconfig:/etc/bind -v /bindlog:/var/log/named \
--restart=always pstauffer/bind:stable

Docker Compose

Check out the docker-compose file in the git repo.

docker-compse up -d

Docker Environment Variables

It's possible to change some variables like the uid/gid of the technical bind user/group or the executed named command. Just pass the variables via docker command to the container or define them in the docker-compose file.

User-ID / GroupID

Example of overwrite of the uid/gid.

NAMED_UID=666
NAMED_GID=666

or via docker-compose file:

    environment:
    - NAMED_UID=666
    - NAMED_GID=666

The default ids in the alpine bind package are:

UID=1000
GID=101

Named Command

It's also possible to add some additional named command options. Just overwrite the following variable:

COMMAND_OPTIONS=<option>

For example if you like to write all logs to the stoud, then change the variable COMMAND like this:

COMMAND_OPTIONS=-g
