I want to deploy the starter image on my kubernetes cluster.
I have three raspberries in a cluster with
> kubectl version -o json ~

Docker version 19.03.8, build afacb8b

node1-pi4 Ready <none> 17h v1.18.2

To try it out I want to deploy the simple image but I get the error CrashLoopBackOff
> kubectl create deployment hello-node --image=k8s.gcr.io/echoserver:1.4
> kubectl get pods ~

The describe is also cryptic to me
