This is a quick recipe for deploying cert-manager and nginx-ingress on GKE to obtain SSL certificates from Lets Encrypt. Whilst this recipe is designed for Google Cloud Platform, it can easily be adapted for other cloud platforms.

We'll begin with a Kubernetes cluster, and we'll obtain authentication credentials.

gcloud container clusters get-credentials my-test-app
kubectl config current-context
kubectl get nodes

This example shows how you can use your data structure as a basis for 
your Firebase security rules to implement role-based security. We store
each user by their Twitter uid, and use the following simplistic approach
for user roles:

0 - GUEST
10 - USER
20 - MODERATOR
