Lab 3.3 Configure Probes - Liveness Probe - goproxy image not loading

I have followed directions to add the goproxy container with the LivenessProbe. However when I create the deployment the goproxy container is not able to start. It has STATUS ImagePullBackoff. I am able to run the simpleApp with and without its own Readiness Probe per the lab. But goproxy is not working.

$ kubectl get pod
