If you'd like to watch along with the recording of the webinar, visit: http://bitn.am/2u5bOnA Serverless computing has given back loads of time and money to developers whose focus is to create new, popular and disruptive applications. Without serverless computing, developers would still be spending most of their time on infrastructure rather than building new features to improve their users' experience. With the move to containers and increased market share for Kubernetes, Bitnami has wanted to stay one step ahead by providing a serverless tool that is also Kubernetes-native, ... Kubeless! Kubeless tackles the challenge of integrating cloud services through small logical units. When creating your new project or application on Kubernetes, Kubeless will allow you to focus on creating a great application with a lightweight and flexible infrastructure. In this video, you will watch and learn: -The benefits of serverless computing on Kubernetes - How to link several cloud services together with small, lightweight pieces of code - How to install Kubeless into your GKE cluster - How to deploy Python and Node.js functions with a straightforward CLI call - An introduction to the Kubeless UI and how to write, update, delete, and deploy functions through it

Containers

Containers are the new application
packaging format.
Bitnami containers give you the latest
stable versions of your application stacks,
focus on coding rather than updating
dependencies or outdated libraries.
And just like Bitnami cloud and VM images,
Bitnami containers are secure, optimized,
consistent, and kept up-to-date.

10. What is Kubernetes?
Kubernetes is an open-source
system for automating
deployment, scaling, and
management of containerized
applications.
More about Kubernetes...
• Open-source, based on 15 years of
container expertise at Google.
• Rich core API for all key primitives
• Cluster Federation, RBAC, Quotas,
Network policies, etc.
• Fastest growing project on GitHub

14. How to get your Hands on k8s ?
• minikube
minikube start
• kubeadm
kubeadm init
kubadm join
• GKE
gcloud container clusters create foobar

15. Benefits of Using Kubernetes on GKE
If you do not want to manage your Kubernetes
cluster, GKE will.
• Don’t have to worry about K8s
master going down
• Don’t have to learn etcd
• Don’t have to worry about container
networking
• Don’t have to worry about upgrading
your Kubernetes master upon new
K8s releases
• One-command to autoscale your
GCE instances
• Has built in authentication and
authorization.
• Built in support for Google Cloud
Monitoring via Heapster
• Built in support for logging cluster
via Google Cloud Logging

16. Setting up Kubernetes in GKE in 5 steps
Enable Google Container Engine API
Activate Google Cloud Shell (or not … )
Create GKE Cluster
Set defaults for gcloud command-line tool
Run a container image!

22. Lambda Examples:

23. FaaS / Serverless
Somewhere in the PaaS spectrum. “ServiceFull”
• Not pushing code ala git push
• Not running fully baked containers
• Transparent infrastructure, scaling and networking
• Fine grained cost management
• source to prod
“Reduce MTTP : Mean Time To Production or MTTD
…”

25. Kubeless: Kubernetes-Native Serverless
Computing
Kubeless Features
• Kubernetes-native serverless
implementation
• Python and Node.js support
• HTTP and Even triggers out of the box
• Prometheus integration
• Serverless framework plugin
• Open Source and non-affiliated
• https://github.com/kubeless/kubeles

26. Deploy a Function
$ kubeless function deploy tweet
--trigger-http
--runtime python27
--handler send-tweet.tweet
--from-file send-tweet.py
--dependencies requirements.txt

27. The Magic Beneath
• Third Party Resource extension (move to Custom
Resource Definition under way)
• A controller written in Golang
• Functions are injected into Pod
• Functions stored in ConfigMaps
• Scaling via Deployment
• Routing via Ingress rules (coming up)
• A CLI that talks to the k8s API server

28. Serverless Framework
● Leading Serverless tool/framework
● Kubeless plugin as first class provided

29. $ serverless create --template kubeless-nodejs --path webinar

31. Roadmap
• Event triggers for Node.js
• Ingress support via CLI
• Additional runtimes (e.g Java, Golang)
• Build pipeline for improved dependency handling
• Support for different types of event systems (e.g nats.io)
• Scheduled function (via k8s cron jobs)
• VScode plugin
• Improved UI
• Additional metadata handling in serverless plugin
