run a task in only ONE pod (of multiple pods)

问题

I am trying to run a process in only ONE docker pod (and not the other n pods),

can I know (from inside a pod/instance)

• am I the first pod?
• how many pods are running?

thanks.

Don't do this. Put that thing in its own deployment (or statefulset more likely) that is unrelated to the others.
