Deployment

Example Function

module.exports = {
    hello: async function (event, context) {
        console.log("event")
        console.log(event.extensions.request.query)
        return "hello"
    }
}

kubeless function deploy <funcName> --runtime nodejs14 \
                                --dependencies package.json \
                                --handler <fileName>.<function> \
                                --from-file <fileName>.js
                                

HttpTrigger using Traefik (this will create an ingress)

apiVersion: kubeless.io/v1beta1
kind: HTTPTrigger
metadata:
  name: hello
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt-prod
spec:
 function-name: hello
 host-name: kubeless.dfinkbeiner.de
 path: hello
 gateway: traefik
 tls-secret: hello-tls

1. Use Bot Father to create a new bot
2. set webhook via
