TLDR; This project simplifies exposing Kubernetes services to the internet easily and securely using Cloudflare Tunnel.

To use the Cloudflare Tunnel Ingress Controller, you need to have a Cloudflare account and a domain configured on Cloudflare. You also need to create a Cloudflare API token with the following permissions: Zone:Zone:Read, Zone:DNS:Edit, and Account:Cloudflare Tunnel:Edit.

Additionally, you need to fetch the Account ID from the Cloudflare dashboard.

Finally, you need to have a Kubernetes cluster with public Internet access.

Take a look on this video to see how smoothly and easily it works:

Want to DIY? The following instructions would help your bootstrap a minikube Kubernetes Cluster, then expose the Kubernetes Dashboard to the internet via Cloudflare Tunnel Ingress Controller.

• You should have a Cloudflare account and a domain configured on Cloudflare.
• Create a Cloudflare API token with the following:
  • Zone:Zone:Read
  • Zone:DNS:Edit
  • Account:Cloudflare Tunnel:Edit
• Fetch the Account ID from the Cloudflare dashboard, follow the instructions here.
• Bootstrap a minikube cluster

minikube start

• Add Helm Repository;

helm repo add strrl.dev https://helm.strrl.dev
helm repo update

• Install with Helm:

helm upgrade --install --wait \
  -n cloudflare-tunnel-ingress-controller --create-namespace \
  cloudflare-tunnel-ingress-controller \
  strrl.dev/cloudflare-tunnel-ingress-controller \
  --set=cloudflare.apiToken="<cloudflare-api-token>",cloudflare.accountId="<cloudflare-account-id>",cloudflare.tunnelName="<your-favorite-tunnel-name>" 

if the tunnel does not exist, controller will create it for you.

• Then enable some awesome features in minikube, like kubernetes-dashboard:

minikube addons enable dashboard
minikube addons enable metrics-server

• Then expose the dashboard to the internet by creating an Ingress:

kubectl -n kubernetes-dashboard \
  create ingress dashboard-via-cf-tunnel \
  --rule="<your-favorite-domain>/*=kubernetes-dashboard:80"\
  --class cloudflare-tunnel

for example, I would use dash.strrl.cloud as my favorite domain here.

• At last, access the dashboard via the domain you just created:

• Done! Enjoy! 🎉

There is also an awesome project which could integrate with Cloudflare Tunnel as CRD, check it out adyanth/cloudflare-operator!
