docker

coredns-docker

Name

docker - enables serving zone data based on docker container names

Description

The docker plugin is useful for development environments so you can access containers by their names. This plugin is not intended for production usage.

Syntax

The plugin is activated by using its name without any additional parameters

. {
  docker
}

Example

The configuration bellow will match containers by their names without using any zone:

. {
  docker
  forward . 8.8.8.8
}

For instance, if you have a container named my-nginx, it will return something like this:

my-nginx.   0      IN      A       172.25.0.2

In case you want my-nginx under a particular zone, you could use:

localdomain {
  docker
}

Then you would get:

my-nginx.localdomain.   0      IN      A       172.25.0.2
