Deploy a Data Plane

To attach a Kong Gateway Operator data plane to Konnect the data plane needs to know which endpoint to connect to, and how to authenticate the requests.

To get the endpoint and the authentication details of the data plane:

1. Log in to Konnect.
2. Navigate to Gateway Manager, choose the control plane, and click New DataPlane Node.
3. In the Create a Data Plane Node page select Kubernetes as the Platform.
4. Click Generate Certificate in step 3.
5. Save the contents of Cluster Certificate in a file named tls.crt. Save the contents of Cluster Key in a file named tls.key.

6. Create a namespace named kong in the Kubernetes cluster:

   kubectl create namespace kong
   

7. Create a Kubernetes secret containing the cluster certificate:

    kubectl create secret tls konnect-client-tls -n kong --cert=./tls.crt --key=./tls.key
   

8. In the Configuration parameters step 4, find the value of cluster_server_name. The first segment of that value is the control plane ID for your cluster. For example, if the value of cluster_server_name is 36fc5d01be.us.cp0.konghq.com, then the control plane ID of the cluster is 36fc5d01be.

9. Replace YOUR_CP_ID with your control plane ID in the following manifest and deploy the data plane with kubectl apply:

                  defaultMode: 420
    ' | kubectl apply -f -
   

   The result should look like this:
