# Use Manifests to install NGINX Gateway Fabric with NGINX Open Source Type of document: How-to guide Product: NGINX Gateway Fabric --- This page describes how to use Manifests to install NGINX Gateway Fabric with NGINX Open Source. It explains how to install the Gateway API resources and add authentication certificates, then deploy NGINX Gateway Fabric and its custom resource definitions. By following these instructions, you will finish with a functional NGINX Gateway Fabric instance for your Kubernetes cluster. **Note:** To learn which Gateway API resources NGINX Gateway Fabric currently supports, view the [Gateway API Compatibility](/ngf/overview/gateway-api-compatibility.md) topic. To install an experimental NGINX Gateway Fabric version view the [Use Manifests to install NGINX Gateway Fabric (experimental) with NGINX Open Source](/ngf/install/manifests/open-source-experimental.md) topic. ## Before you begin To complete this guide, you will need the following pre-requisites: - [A supported Kubernetes version](/ngf/overview/technical-specifications.md) - A functional Kubernetes cluster ## Install the Gateway API resources **Note:** If you have already installed Gateway API resources in your cluster, ensure they are a version [supported by NGINX Gateway Fabric](/ngf/overview/technical-specifications.md) To install the Gateway API resources, use `kubectl kustomize`: ```shell kubectl kustomize "https://github.com/nginx/nginx-gateway-fabric/config/crd/gateway-api/standard?ref=v" | kubectl apply -f - ``` #### Example output ```text customresourcedefinition.apiextensions.k8s.io/gatewayclasses.gateway.networking.k8s.io created customresourcedefinition.apiextensions.k8s.io/gateways.gateway.networking.k8s.io created customresourcedefinition.apiextensions.k8s.io/grpcroutes.gateway.networking.k8s.io created customresourcedefinition.apiextensions.k8s.io/httproutes.gateway.networking.k8s.io created customresourcedefinition.apiextensions.k8s.io/referencegrants.gateway.networking.k8s.io created ``` You should also create the _nginx-gateway_ namespace, which is used by the Manifest files by default: ```shell kubectl create namespace nginx-gateway ``` ## Install cert-manager Install cert-manager onto the cluster using Helm with Gateway API features enabled. - Add the Helm repository. ```shell helm repo add jetstack https://charts.jetstack.io helm repo update ``` - Install cert-manager, and enable the GatewayAPI feature gate: ```shell helm install \ cert-manager jetstack/cert-manager \ --namespace cert-manager \ --create-namespace \ --set config.apiVersion="controller.config.cert-manager.io/v1alpha1" \ --set config.kind="ControllerConfiguration" \ --set config.enableGatewayAPI=true \ --set crds.enabled=true ``` ## Add certificates for secure authentication **Note:** These steps use a self-signed issuer, which should not be used in production environments. For production environments, you should use a real [CA issuer](https://cert-manager.io/docs/configuration/ca/). First, create a CA (certificate authority) issuer: ```yaml kubectl apply -f - <= v1.18.0, the default value changed from `Never` to `Always`. certificate.cert-manager.io/nginx-gateway-ca created issuer.cert-manager.io/nginx-gateway-issuer created ``` You will then need to create a server certificate for the NGINX Gateway Fabric control plane (server): **Note:** The default service name is _nginx-gateway_, and the namespace is _nginx-gateway_, so the `dnsNames` value should be `nginx-gateway.nginx-gateway.svc`. This value becomes the name of the NGINX Gateway Fabric control plane service. ```yaml {hl_lines=[13]} kubectl apply -f - <
