# From my webinar for Sysdig - Exploring Kubernetes 1.18

# Create A KinD or k3s cluster with no IngressController
# Run `arkade install ingress-nginx` to add IngressNginx to the cluster as your IngressController

# Save and apply all the Kubernetes YAML files below

# Forward the IngressController
# kubectl port-forward ingress-nginx-controller 8080:80

# Access our service via Ingress:
# curl localhost:8080 -d Sysdig -H "Host: openfaas-figlet.local"
