# Add-on dns

**Compatibility**:
**Source**: [CoreDNS](https://coredns.io/)

This deploys CoreDNS to supply address resolution services to
Kubernetes.

This service is commonly required by other addons, so it is
recommended that you enable it.

```
microk8s enable dns
```

By default it forwards requests to the system-defined servers in `/etc/resolv.conf` for resolving
addresses. This can be changed when you enable the addon, for example:

```
microk8s enable dns:1.1.1.1
```

(for multiple DNS addresses, a comma-separated list should be used)

The forward dns servers can also be altered after enabling the addon
by running the command:

```
microk8s kubectl -n kube-system edit configmap/coredns
```

This will invoke the `vim` editor so that you can alter the configuration.

> Note: You can set a different default editor by setting the `KUBE_EDITOR` environment variable. E.g. `export KUBE_EDITOR="/usr/bin/nano"`

The addon can be disabled at any time:

```
microk8s disable dns
```

…but bear in mind this could have implications for services and pods which
may be relying on it.
