I have followed all the steps in this guide
and verified that they all completed successfully.
But when I get to the last part where I preview the application on port 8080 I get the error:
Error: Could not connect to Cloud Shell on port 8080.
Ensure your server is listening on port 8080 and try again.I have also tried to change the port to 8084 but same result.
Any suggestions on how to debug/fix this?
Below the result of some of the last commands that I executed on my local machine using the locally installed gcloud client:
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
cd-jenkins-7c786475dd-bz7kj 1/1 Running 0 2m
$ printf $(kubectl get secret cd-jenkins -o jsonpath="{.data.jenkins-admin-password}" | base64 --decode);echo
********
$ export POD_NAME=$(kubectl get pods -l "component=cd-jenkins-master" -o jsonpath="{.items[0].metadata.name}")
$ kubectl port-forward $POD_NAME 8080:8080 >> /dev/null &
[1] 24685
$ echo $POD_NAME
cd-jenkins-7c786475dd-bz7kj
Accessing Jenkins through your local machine:
You can run all kubectl commands within your local machine, but if you run kubectl port-forwarding in your local machine you will have to access the Jenkins page through this address http://localhost:8080/.
Accessing Jenkins through Google Cloud Console:
In the Google Cloud Console, on the top right menu just click on the following icon >_ (Activate Cloud Shell) then run the port-forwarding command:
export POD_NAME=$(kubectl get pods --namespace default -l "app.kubernetes.io/component=jenkins-master" -l "app.kubernetes.io/instance=cd" -o jsonpath="{.items[0].metadata.name}")
kubectl port-forward $POD_NAME 8080:8080 >> /dev/null &Now if you click on the icon Web preview -> Preview on port 8080 you should see the login page.
Just remember that the port is only forwarded while the kubectl process is running.
