Note

The ngrok-operator is production-ready and supported for use in production environments. However, it is currently pre-1.0.0, and as such, the public API (including helm values and CRDs) should be considered unstable.

While we aim to minimize disruption, breaking changes may be introduced in minor or patch releases prior to the 1.0.0 release. Users are encouraged to pin versions and review release notes when upgrading.

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-operator ngrok/ngrok-operator \
  --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

To enable using the ngrok-operator with the Kubernetes Gateway API, you need to install the Gateway CRDs if you haven't already, and then include gateway.enabled in your helm --set or values.yaml.

See the Kubernetes Gateway API Quickstart for setup and installation steps.

YAML Manifests

Apply the sample combined manifest from our repo:

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