Functions

func AutoUpdate

func AutoUpdate(ctx context.Context, runtime *libpod.Runtime, options entities.AutoUpdateOptions) ([]*entities.AutoUpdateReport, []error)

/ AutoUpdate looks up containers with a specified auto-update policy and acts accordingly.

If the policy is set to PolicyRegistryImage, it checks if the image on the remote registry is different than the local one. If the image digests differ, it pulls the remote image and restarts the systemd unit running the container.

If the policy is set to PolicyLocalImage, it checks if the image of a running container is different than the local one. If the image digests differ, it restarts the systemd unit with the new image.

It returns a slice of successfully restarted systemd units and a slice of errors encountered during auto update.
