dind-port-forward.sh -> invalid resource name ?

[stock99]

if i execute the script, I will get error look similar below:
root@ffdl2018:~/FfDL/bin# kubectl port-forward pod/$ui_pod $ui_port:8080
error: invalid resource name "pod/": [may not contain '/']

So I tried to remove the pod/ thinking maybe newer version of kubeadmin-dind look like the pod/ , but i get different error below. Can someone help me with the error message below?

Hi @stock99, it looks like the script didn't find the right pod name from your Kubernetes cluster. Can you echo your pod name with the below commands? Thanks.

ui_pod=$(kubectl get pods | grep ffdl-ui | awk '{print $1}')
restapi_pod=$(kubectl get pods | grep ffdl-restapi | awk '{print $1}')
grafana_pod=$(kubectl get pods | grep prometheus | awk '{print $1}')

echo $ui_pod
echo $restapi_pod
echo $grafana_pod

Also, the pod/ format was introduce from kubectl client v1.10.0 and above, so I would recommend to update your kubectl client to a version after v1.10.0.

Hi Tomcli,
It looks like the kubectl come with kubeadm-dind installation script isn't the latest one (1.8.x). If i installed the latest version via snap, the installation script there seem to enforce the use of 1.8.15 still. Should I adjust any environment variable?

echo $ui_pod
ffdl-ui-b6cbb98f-c4zpm
echo $restapi_pod
ffdl-restapi-84bcb74478-t8df6
echo $grafana_pod

Hi @stock99, I updated the script at #150 to make it able to run with K8S 1.8.x. Let me know if you encounter any new issue.

[stock99]

seem to be ok now after removing 'pod/' in the script. The connection error in the opening post was because I fat-fingered on one of the export statement in dind installation.

But then I got an error message for the test routine make test-push-data-s3 && make test-job-submit :

Anyone can help? I got this error messages when running the make test-job-submit
