Forward traffic from a non-default port to the platform admin console in Continuous Delivery for Puppet Enterprise 4.2.3

My network infrastructure only allows web browsers to connect to standard web ports like 80, 443, and 8080. I can’t use the default port (8800). I need to forward traffic from port 8080 to the platform admin console.

Version and installation information

Product: Continuous Delivery for Puppet Enterprise
Version: 4.2.3
Installation type: Any

Solution

Use these steps to create a service to forward traffic from the desired port to the platform admin console.

1. Set the nodePort to the desired port. On the Continuous Delivery for PE host system, create a file named kotsadm-nodeport.yaml with the following contents. In this example, connections to port 8080 are forwarded to the platform admin console.

   apiVersion: v1 kind: Service metadata: name: kotsadm-nodeport namespace: default spec: ports: - name: http port: 3000 protocol: TCP targetPort: http nodePort: 8080 selector: app: kotsadm type: NodePort

2. Apply the change to the kotsadm service. On the command line, run kubectl apply -f kotsadm-nodeport.yaml

3. Confirm the change took effect. Run kubectl get svc kotsadm-nodeport

   The new nodePort will be displayed in the output in the PORT(S) column. When you connect to the Continuous Delivery for PE host on port 8080, the browser should redirect to the platform admin console.

   # kubectl get svc kotsadm-nodeport
   NAME               TYPE       CLUSTER-IP   EXTERNAL-IP   PORT(S)         AGE
   kotsadm-nodeport   NodePort   10.96.2.90   <none>        3000:8080/TCP   47m

To stop forwarding

If port forwarding is no longer required, remove the kotsadm-nodeport service. On the command line, run kubectl delete svc kotsadm-nodeport
