pub fn image_refresh_plan(config: &Config) -> Vec<ImageRefresh>Expand description
Every container image the daemon downloads in the background, once per (host, image, platform).
Every container target is covered, including Apple’s container engine.
A never policy is the one opt-out. The rest differ only in when they
download: always and newer pull on every refresh, while the others
pull only when the host has no copy of the image.
Several targets often share one image on one host, and that needs one download. When two such targets disagree about when to pull, the merged entry takes the more eager of the two.
