Game of pod #1 - Issue with command - argument

Kubernetes
#1

Hello,

In the game of pod #1, I Don’t manage to validate the command and argument for the creation of the Drupal pod (the web server)

I have put this :

image713×48 4.86 KB

But it still does not validate it…

And after many test it does not validate it. I came to the point that I suspect that the validation would be in error.

Can you please help ?

Anyway thanks for this great lab !! I enjoy it a lot…

  -c
Args:
  cp -r /var/www/html/sites/ /data/ && chown -R www-data:www-data /data/
State:          Terminated
  Reason:       Completed
  Exit Code:    0

Thanks for your help,

Cyril

Can you post the status of the pod , specifically the init Container, did it complete successfully?
