k3s: use images without a registry (docker save → k3s ctr images import) and clean up the leftovers
docker save -o app.tar app:v1; k3s ctr images import app.tar on every node; imagePullPolicy: Never. For several nodes, /var/lib/rancher/k3s/agent/images/ or –embedded-registry. Cleanup: k3s crictl rmi –prune.
