pub fn image_refresh_plan(config: &Config) -> Vec<ImageRefresh>Expand description
Every container image a background refresh keeps current, once per (host, image, platform).
Targets the host can already satisfy are left out: digest pins, versioned
tags, and the explicit missing and never policies. Apple’s container
engine is left out too; it still refreshes its image during provisioning.
Several targets often share one image on one host, and that needs one pull.
