# See: https://github.com/wireapp/wire-server/blob/develop/charts/coturn/values.yaml
# And: https://github.com/wireapp/wire-server/blob/develop/charts/coturn/README.md

# use nodeSelector only if you are planning on using less than 3 pods in your installation and wish to pin coturn to specific nodes
nodeSelector:
wire.com/role: coturn

coturnTurnListenIP: '192.168.122.23'

replicaCount: 3
coturnTurnListenIP: "__COTURN_POD_IP__"
coturnTurnExternalIP: "__COTURN_EXT_IP__"
coturnTurnRelayIP: "__COTURN_POD_IP__"
```

Where `192.168.122.23` is the IP address of the machine where you want to run Coturn (in our example, the third kubernetes node, `kubenode3`).
Annotate nodes with the wire.com/external-ip annotation if you are behind 1:1 NAT to make coturn aware of its external IP address.

an example of how to annotate would be good here.


ie.
```
d kubectl annotate node kubenode1 wire.com/external-ip=IP.ADDRESS
```

## Create a `secret.yaml` file for the Coturn secrets.

d kubectl logs coturn-0
```

Check if the pod has the correct IP configuration in place.

```bash
d kubectl exec -it coturn-0 -- bash
grep ip= coturn-config/turnserver.conf

# output will look something like this

listening-ip=xxx.xxx.xxx.xxx
relay-ip=xxx.xxx.xxx.xxx.xxx
external-ip=xxx.xxx.xxx.xxx
```

## Appendix: Note on migration.

The current guide is written with the assumption that you are setting up Coturn for the first time, on a fresh Wire-Server installation.
