## Notes

### Linode

ProxyProtocol needs to be enabled for ingress-nginx to see the clients IP in ingress log.

Add the ProxyProtocol annotation to the ingress-nginx service:
```
annotations:
	service.beta.kubernetes.io/linode-loadbalancer-proxy-protocol: v2
```

Update the ingress-nginx ConfigMap to make nginx expect ProxyProtocol data:
```
data:
  use-proxy-protocol: "true"
```
