The kubekins image got updated from containerd 1.7 to 2.2, which broke local-up-cluster.sh in the CI because more recent containerd uses single quotation marks around strings instead of double quotation marks as before. The search/replaced with sed no longer matched, causing containerd to fail mounting overlayfs on the default /var/lib/containerd. We have to use the emptyDir host mount under /docker-graph. The fix is to relax the search term slightly so that it accepts both kinds of quotation marks.
