Leverage ngrok for your ingress in your Kubernetes cluster. Instantly add load balancing, authentication, and observability to your services via ngrok Cloud Edge modules using Custom Resource Definitions (CRDs) and Kubernetes-native tooling. This repo contains both our Kubernetes Ingress Controller and the Kubernetes Gateway API

Installation

Helm

Note We recommend using the Helm chart to install the operator for a better upgrade experience.

Add the ngrok Kubernetes Operator Helm chart:

helm repo add ngrok https://charts.ngrok.com

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] (https://dashboard.ngrok.com/get-started/setup). The ngrok Kubernetes Operator uses them to authenticate with ngrok and configure and run your network ingress traffic at the edge.

For a more in-depth installation guide follow our step-by-step Getting Started guide.

Gateway API Preview

To install the developer preview of the gateway api we'll make the following changes to the above instructions.

Install the v1 gateway CRD before the helm installation.

kubectl apply -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.0.0/standard-install.yaml

Then, during the helm install set the experimental gateway flag.

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

YAML Manifests

Apply the sample combined manifest from our repo:

kubectl apply -n ngrok-ingress-controller \
  -f https://raw.githubusercontent.com/ngrok/kubernetes-ingress-controller/main/manifest-bundle.yaml

For a more in-depth installation guide follow our step-by-step Getting Started guide.
