The document discusses the integration of serverless computing with Kubernetes using Kubeless on Google Container Engine. It outlines the advantages of Kubernetes, the role of Bitnami in providing pre-packaged applications, and details how to deploy serverless functions using Kubeless. Additionally, it includes a roadmap for future features and provides contact information for further assistance.
Going Serverless with Kubeless In Google Container Engine (GKE)
- 1. Going Serverless with Kubeless In Google Container Engine
- 2. Host Mavian Ruiz Partner Marketing Manager, Bitnami
- 3. Speaker Sebastien Goasguen Sr. Director of Cloud Technologies, Bitnami
- 4. Agenda • Who is Bitnami? • What is Kubernetes? • Benefits of Kubernetes and Google Container Engine • What is Serverless? • Introduction to Kubeless • Bitnami Demo: How to go serverless in Google Container Engine with Kubeless • Live Q&A: Live Q&A with Sebastien– Ask your questions via the WebEx chat window & We’ll get to them at the end. ☺
- 5. Who is Bitnami? 150+ Apps Server-side, Mainly Open Source, Commercial Titles Growing 1MM+ New Deployments Each Month 42+ Categories For Dev, Ops & Business Users Loved by Devs, Trusted by Ops • Ready-to-Run – Fully-configured and ready to run • Up to date – Latest versions of apps are always available • Integrated – Target platform readied; including monitoring • Tuned – Consistently configured for best performance • Trusted – Optimized for security and performance
- 6. e.g Google Cloud Launcher
- 7. About Bitnami Containers 25 Turnkey Application & Infrastructure Containers 7 Development Containers Loved by Devs, Trusted by Ops 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give you the latest stable versions of your application stacks, focus on coding rather than updating dependencies or outdated libraries.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! * For detailed guide: https://cloud.google.com/container-engine/docs/quickstart 1 2 3 4 5

- 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 s

- 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
