ch8 : ErrImagePull when create pod with curl.yaml

[周磊]

when i create pod with curl.yaml, I got an error

controlplane $ k get pod
NAME   READY   STATUS         RESTARTS   AGE
curl   0/1     ErrImagePull   0          5s

here is the events:

  Warning  Failed     2s (x2 over 16s)  kubelet, controlplane  Error: ErrImagePull

looks like image tutum/curl not exists, what can I do to handle this error?
