I'm launching master components from static pods with kubelet. kubelet won't launch my pods. Gives this error:

Aug 13 23:33:27 k8s-any-217-deb3a12-master docker[6943]: I0813 23:33:27.519134    6964 docker.go:187]
Inspected image ("sha256:8ac6572ec6b92710085d6181de1d17650e129ef34d0229e4ca7613859a3b5a4d") does not match docker.io/colemickens/hyperkube-amd64:217.9beff63

I suspect this very recent change: 875fd16

Can you advise anything @dims?

$ sudo docker inspect docker.io/colemickens/hyperkube-amd64:217.9beff63
