Kubernetes task failed wrongly

Kubernetes
#1

Hi,

Today, I have received one task for Sr Devops and it’s related to Kubernetes. I have performed that task and created Persistent Volume, Persistent Volume Claim, Service, Deployment and POD but still task resulted in failure. I think there is something wrong in result checking process for this task.

Please find set-1.jpg and set-2.jpg files. In Set-1. jpg file, you can see that all required Kubernetes objects have been created successfully. As soon as I have clicked on “Check” button, all of these objects disappered and task is marked as failure. Set-2.jpg is the screenshot after task marked as failure.

Hi @GKunal

Can you please try this task again, its marked pending for you.

#5

Hi,

But as I have mentioned that I have already performed this task but because of validation process error it was marked with failure.

Still, Do I need to perform this task again?

Thanks,
Kunal Gandhi

Yes, because it seems to be working fine on our end. Also please save a copy of the final template you are going to apply and in case task fails again share the same with us.

Hi,

As I have already given screenshot proof of task done and I have kept final template copy of task done. I had finished task in less than 15 mins. As you can see in first screenshot that it’s showing all the kubernetes objects created and in second screenshot, it’s not showing objects created so, it got disappeared automatically after clicking on “Check” button. Also, you can check video recording of task done from your end. When I had done review of task then in video recording I was able to see that task was performed all well.

It’s not allowed to attach .yml file here so, I can’t send it to you.

Please let me know that how can I share final template file of task completed with you.

Thanks,
Kunal Gandhi

You can copy/paste the yaml and can DM me.

Please find yaml file of task completed as following. I am not sure that copy/pasting yaml file here will preserve formatting or not.

apiVersion: v1

I can see that formatting is getting changed after copying it here but It’s a valid yaml file content. Also, there is “—” between each of the kubernetes object definition in file which is also getting disappeared here.
