+## 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"
+```
