```auto
kubernetes: ls

```

Not sure why the image for kubernetes is set to `ls` but it makes sense that RKE is trying to pull the image `ls` if you configure that. In general, I would step away from using `system_images` and remove it from `cluster.yml` and configure `kubernetes_version` based on versions that are listed when you use `rke config -l -a`.
