Issue #, if available:
Description of changes:
follow up for #1810. when there are no images to cache during worker installation, the blank variable
img
will be passed to thepull-image.sh
script.the reason for the issue is the fallback
"${VAR[@]:-}"
still results in a single loop iteration over the empty string""
, but would not do so with${VAR[@]:-}
this PR short circuits when the loop variable is blank, which fixes this case and other cases where the image is actually blank, and also adds logging to help diagnose issues with the images in the future.
