Kubernetes Workshops

This repository contains both complete workshops, as well as segmented workshop modules that can be combined to create Kubernetes workshops of various lengths and focus.

Modules contain a README.md that walks through the module. If code, configuration, or scrips are needed, it is included and tested.

This is not an official Google product.

Individual Modules

Status: Not Started --> In Progress --> Draft --> Ready

Overview of Modules

This is incomplete. These are just brainstorming / rough notes.

Quickstart

• Quick
• Not complex, uses kubectl run, kubectl expose.
• Demonstrates the ease of using Kubernetes without learning all the concepts and config files up front.

Cluster Bring Up

• Uses the open source kubernetes release with cluster/kube-up.sh for cloud bringup
• Option for local docker

Core Kubernetes Concepts

• Introduce one concept at a time, and then use that concept
  • Order: pod, service, rc, deployment
• go over a declarative pod representation of quickstart app
  • contains 1 pod
• logs, exec, port forwarding
• introduce service
• overview pods, labels, selectors, and services
• change pod to RC
• discuss RC
• scale pod up
• introduce deployments
• move everything under a deployment
• update to new versions of our app, quick rolling update
  • lightweight here - more detail in "Advanced" module

Storing State

• Deploy an app with MySQL
• multiple iterations where to store the data, how it goes away
  • start with host volume, end at persistent disk
• More of a lecture module, slides discuss state in greater length

Dockerize an App

• Start with an app
• Write the Dockerfile
• build
• push to registry

Advanced Concepts

• Lecture

  • App/container patterns http://blog.kubernetes.io/2015/06/the-distributed-system-toolkit-patterns.html
  • mapping non-containerized apps

• Hands on:

  • A/B deployment
  • Canary patterns
  • Rolling Deployments
  • Autoscaling

Networking

• More of a lecture module, slides discuss networking in greater length

• Types of external services VIP/nodeport, run service with each and see how we get into the cluster

• discuss subnets, explore on running nodes

• How K8s networking works

• Setting up an external load balancer - Nginx

• Ideas on how to plug into your environment

Troubleshooting

• Logging & monitoring
• Troubleshooting / Debugging

Putting it all together

• deploy a production ready app

• Use all the above

• Build up a significant realistic app

• ( not so much lecture, just deploy all this stuff: )

• web frontends, caching, backend jobs, datastore, load testing

• Logging & monitoring

• Troubleshooting

• Autoscaling
