Tried git commit --amend --no-edit && git push -f to trigger a re-run of the cla-signed bot, but it's still red. I've signed a CLA, as noted above. I don't particularly need this exact PR to land, but it would be nice to get an image with up-to-date alpine. Please let me know if I can be of assistance. Thanks!
