A short code listing to run spin on DigitalOcean Kubernetes

DigitalOcean-Kubernetes-Spin.sh

doctl kubernetes cluster create kwasm
# Takes some time ...
doctl kubernetes cluster kubeconfig save kwasm
# Install KWasm operator
helm repo add kwasm http://kwasm.sh/kwasm-operator/
helm install -n kwasm --create-namespace kwasm-operator kwasm/kwasm-operator
# Provision Nodes
kubectl annotate node --all kwasm.sh/kwasm-node=true
