What is the difference between an ephemeral volume and a persistent volume?

Question

Accepted Answer

Ephemeral volumes are tied to a Pod's lifetime, persistent volumes exist beyond it — Ephemeral volumes (like emptyDir) are created and destroyed with the Pod. Persistent volumes (PVs) have a lifecycle independent of any Pod, preserving data across Pod restarts and rescheduling.

Answer

Ephemeral volumes are faster because they use in-memory storage, persistent volumes use slower disk

Answer

Ephemeral volumes use RAM exclusively, while persistent volumes are always backed by physical disk

Answer

There is no difference — both types persist data independently of the Pod's lifecycle
