LAB 280 - Unable to save file through OC edit command

[Rajbatra]

Hi,

I am doing Lab, there i am trying to save file through OC edit command, but it is showing error.

student@workstation ~]$ oc edit deployment/hello
A copy of your changes has been stored to "/tmp/oc-edit-1fi7k.yaml"
error: Edit cancelled, no valid changes were saved.

Let us know , how to save file through oc edit command?

Thanks

Hi Rakjumar

Seems that the changes you are doing in the deployment are being rejected when sent back to OCP.

This may be caused by many reasons, like invalid values, wrong format, etc.

Can you clarify what exact changes are you applying?

Kind regards

Hello ,

I don't think this was an issue because it went smooth for me. 

Could you please redo the exercise and share here the screenshot  if you face the issue again ?

4.1. Log in to your OpenShift cluster as the developer user.

Login successful.

Using project "schedule-pods".
4.2. Modify the deployment resource for the hello application to select a development

Add the highlighted lines below to the deployment resource, indenting as shown.

Hello ,

I again created lab and have re-executed the lab exercise without any issues.

So, it again confirms there is no issues as such in this part.

I would request you to carefully edit the file with proper indentation and ensure  no other  errors while editing , save the file with :wq! and it will work.

Hello ,

hi ,

i have shared my screenshots above which u can see the nodeSelector entry i edited correctly and when i save and exit got the error . 

i did many times .. only this particular task in the whole D0280 got issue which i am unable to find the issue still . 

Do you want to setup zoom session to see while i am doing the lab ?
