This page describes the lifecycle of a Pod. Pods follow a defined lifecycle, starting in the Pending phase, moving through Running if at least one of its primary containers starts OK, and then through either the Succeeded or Failed phases depending on whether any container in the Pod terminated in failure. Like individual application containers, Pods are considered to be relatively ephemeral (rather than durable) entities. Pods are created, assigned a unique ID (UID), and scheduled to run on nodes where they remain until termination (according to restart policy) or deletion.

SkyPilot uses the venerable SQLite for state management. SQLite can handle millions of QPS, and terabytes of data. However, our efforts to scale our Managed Jobs feature ran up against the one downfall of SQLite: many concurrent writers. Since SkyPilot typically runs as a CLI on your laptop, we wanted to stick with SQLite, so we decided to figure out how we can make it work. We were very surprised with some of our findings.
