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dependencies or outdated libraries.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.

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

Benefits of Using Kubernetes on GKEIf 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

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!

kube is the perfect platform to build

systems on. All the core primitives are

available and the system is extendable

Kubernetes Native Serverless

Solution

Via Twitter from Serverless Austin...

Knitting services together through

functions

Or Gluing legos ...

Lambda Examples:

https://aws.amazon.com/lambda/

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

…”

Solutions

Kubeless: Kubernetes-Native Serverless

ComputingKubeless 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

Deploy a Function

$ kubeless function deploy tweet \

--trigger-http \

--runtime python27 \

--handler send-tweet.tweet \

--from-file send-tweet.py \

--dependencies requirements.txt

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

Serverless Framework

● Leading Serverless tool/framework

● Kubeless plugin as first class provided

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

DEMO: Kubeless

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

• Support for packaging function (e.g .zip files)

• Functions repository (https://github.com/kubeless/functions)
