helm repo add incubator https://kubernetes-charts-incubator.storage.googleapis.com/

helm install --name my-kubeless --set ui.enabled=true --set ui.service.type=LoadBalancer --namespace kubeless incubator/kubeless

Serverless Application on top of Kubernetes with Kubeless

# deploy your serverless application
kubeless function deploy awesomeserverless \
                    --runtime nodejs8 \
                    --handler awesomeserverless.handler \
                    --from-file awesomeserverless.js

# expose your serverless application with ingress rule
kubeless trigger http create myawesomeserverless --function-name awesomeserverless --path myawesomeserverless --hostname ildev.io
