ngrok Kubernetes Ingress Controller

Leverage ngrok for your Kubernetes Ingress. Instantly add load balancing, authentication, and observability to your services via ngrok Cloud Edge modules using Custom Resource Definitions (CRDs) and Kubernetes-native tooling.

Installation

Helm

Note We recommend using the Helm chart to install the controller for a better experience for upgrades.

Add the ngrok Ingress Controller Helm chart:

helm repo add ngrok https://ngrok.github.io/kubernetes-ingress-controller

Then, install the latest version (setting the appropriate values for your environment):

export NAMESPACE=[YOUR_K8S_NAMESPACE]
export NGROK_AUTHTOKEN=[AUTHTOKEN]
export NGROK_API_KEY=[API_KEY]

helm install ngrok-ingress-controller ngrok/kubernetes-ingress-controller \
  --namespace $NAMESPACE \
  --create-namespace \
  --set credentials.apiKey=$NGROK_API_KEY \
  --set credentials.authtoken=$NGROK_AUTHTOKEN

Note The values for NGROK_API_KEY and NGROK_AUTHTOKEN can be found in your ngrok dashboard and are used by your ingress controller to authenticate with ngrok for configuring and running your network ingress traffic at the edge.

Known Issues

Note

This project is currently in beta as we continue testing and receiving feedback. The functionality and CRD contracts may change. It is currently used internally at ngrok for providing ingress to some of our production workloads.

Current issues of concern for production workloads are being tracked here and here.
