Creating a Provider

All providers follow the same pattern:

1. Create a Secret

$ kubectl create secret generic my-provider-credentials \
--from-literal=key=VALUE

2. Create TunnelProvider

apiVersion: ktube.dev/v1alpha1
kind: TunnelProvider
metadata:
  name: my-provider
spec:
  type: cloudflare  # or ngrok, devtunnels
  credentialsRef:
    name: my-provider-credentials

3. Reference in TunnelBinding

apiVersion: ktube.dev/v1alpha1
kind: TunnelBinding
metadata:
  name: my-binding
spec:
  tunnelRef:
    name: my-tunnel
  service:
    name: my-service
    port: 8080
