[Unbound](https://unbound.net/) is a validating, recursive, and caching DNS resolver.

Note that this image is [distroless](https://github.com/GoogleContainerTools/distroless)!

> "Distroless" images contain only your application and its runtime dependencies. They do not contain package managers, shells or any other programs you would expect to find in a standard Linux distribution.

## Usage/Examples

Run a recursive dns server on host port 53 with the default configuration.

```bash
docker run --name unbound \
  -p 53:53/tcp -p 53:53/udp \
  klutchell/unbound
```

Optionally mount [custom configuration](https://unbound.docs.nlnetlabs.nl/en/latest/manpages/unbound.conf.html) from a host directory.
Files must be readable by user/group `101:102` or world.

```bash
docker run --name unbound \
  -p 53:53/tcp -p 53:53/udp \
  -v /path/to/config:/etc/unbound/custom.conf.d \
  klutchell/unbound
```

Examples of docker-compose usage can be found in [examples](examples).
