### Prepare phone-home pod
[Remember](/kubernetes/loadbalancer/) how our load balancer design ties a phone-home container to another container using a pod, so that the phone-home container can tell our external load balancer (_using a webhook_) where to send our traffic?

Since we deployed Traefik using helm, we need to take a slightly different approach, so we'll create a pod with an affinity which ensures it runs on the same host which runs the Traefik container (_more precisely, containers with the label app=traefik_).

We're doneburgers! 🍔 We now have all the pieces to safely deploy recipes into our Kubernetes cluster, knowing:
1. Our HTTPS traffic will be secured with LetsEncrypt (thanks Traefik!)
2. Our non-HTTPS ports (like UniFi adoption) will be load-balanced using an free-to-scale [external load balancer](/kubernetes/loadbalancer/)
3. Our persistent data will be [automatically backed up](/kubernetes/snapshots/)

Here's a recap:
* [Start](/kubernetes/start/) - Why Kubernetes?
* [Design](/kubernetes/design/) - How does it fit together?
* [Cluster](/kubernetes/cluster/) - Setup a basic cluster
* [Load Balancer](/kubernetes/loadbalancer/) Setup inbound access
* [Snapshots](/kubernetes/snapshots/) - Automatically backup your persistent data

## Where to next?
I'll be adding more Kubernetes versions of existing recipes soon. Check out the [MQTT](/recipes/mqtt/) recipe for a start!

## Chef's Notes
1. It's kinda lame to be able to bring up Traefik but not to use it. I'll be adding the oauth_proxy element shortly, which will make this last step a little more conclusive and exciting!
### Tip your waiter (support me) 👏
Did you receive excellent service? Want to make your waiter happy? (_..and support development of current and future recipes!_) See the [support](/support/) page for (_free or paid)_ ways to say thank you! 👏
