The document discusses building a Raspberry Pi Kubernetes cluster to run OpenFaas serverless functions. Some key points are: 1. A Raspberry Pi cluster can provide cloud-like capabilities at home by pooling hardware resources and allowing elastic scaling. 2. Kubernetes provides declarative deployments, configuration, service discovery, high availability, and elastic capacity for containers. 3. OpenFaas is a serverless framework that uses Docker containers and Kubernetes to build and run functions as a service.

2. Agenda
Why build a RPi Cluster?
What Counts as Cloud?
Top community Cluster
Why do we need Kubernetes?
Intro to Kubernetes & and serverless functions with OpenFaas

3. Why build a Rpi Cluster?
1. It is the CLOUD in your HOME!
2. Be your own boss - you are the Root
3. Direct access to hardware - you can see what is
happening on your tiny Cloud

4. What is the Cloud and what does it look like?
Pooled computing resources available to any subscribing users
Virtualized computing resources to maximize hardware utilization
Elastic scaling up or down according to need
Automated creation of new virtual machines or deletion of existing ones
Resource usage billed only as used

6. Private Cloud

9. Who needs a orchestrator anyway?

11. Docker Container
Nginx Container
Docker run -d -p 80:80
--restart=always
--name=nginx-deployment
nginx :latest

12. Orchestration add:
Declarative deployments
Configuration - YAML
Programmable API
Service discovery
High availability (HA)
Elastic capacity
Security & extensibility

13. Demo

15. Kubernetes components

17. OpenFaas
It is a community project, lead by Alex Ellis who is a Docker Captain. OpenFaas is a
serverless framework to build functions as a service using Docker containers and
kubernetes.
