Cloudflare Kubernetes Gateway

Manage Kubernetes ingress traffic with Cloudflare Tunnels via the Gateway API.

Getting Started

1. Install v1 or later of the Gateway API CRDs: kubectl apply -k github.com/kubernetes-sigs/gateway-api//config/crd?ref=v1.0.0
2. Install cloudflare-kubernetes-gateway: kubectl apply -k github.com/pl4nty/cloudflare-kubernetes-gateway//config/default
3. Find your Cloudflare account ID
4. Create a Cloudflare API token with the Account.Cloudflare Tunnel and DNS.Zone permissions
5. Use them to create a Secret: kubectl create secret -n cloudflare-gateway generic cloudflare --from-literal=ACCOUNT_ID=your-account-id --from-literal=TOKEN=your-token
6. Create a file containing your GatewayClass, then apply it with kubectl apply -f file.yaml:

apiVersion: gateway.networking.k8s.io/v1
kind: GatewayClass
metadata:
  name: cloudflare
spec:
  controllerName: github.com/pl4nty/cloudflare-kubernetes-gateway
  parametersRef:
    group: ""
    kind: Secret
    namespace: cloudflare-gateway
    name: cloudflare

1. Create Gateways and HTTPRoutes to start managing traffic!

Features

The v1 Core spec is not yet supported, as some features (eg header-based routing) aren't available with Tunnels. The following features are supported:

• HTTPRoute hostname and path matching
• HTTPRoute Service backendRefs without filtering or weighting
• Gateway gatewayClassName and listeners only
• GatewayClass Core fields
