Introduction to Kubernetes

Published by O'Reilly Media, Inc.

Managing distributed applications

April 11 & 13, 2017

Noon - 3 p.m. Coordinated Universal Time

This event has ended.

What you’ll learn and how you can apply it

By the end of this live, hands-on, online course, you’ll understand:

  • The Kubernetes cluster architecture
  • Basics of Kubernetes installation
  • The API resources and endpoints
  • How to interact with a Kubernetes cluster using kubectl
  • How to use the Kubernetes primitives to build a scalable containerized application

And you’ll be able to:

  • Interact with a Kubernetes cluster using the API and the kubectl CLI
  • Build distributed applications using the core API resources
  • Explore all the Kubernetes primitives and understand how they will integrate with their enterprise workflow and processes.
  • Perform rolling-updates and rollbacks of your applications
  • Expose your applications using Kubernetes services
  • Monitor your cluster using Prometheus

This live event is for you because…

  • You’re an application developer and want to understand how to prepare your containerized application for Kubernetes.
  • You’re an application developer who is building Docker images and want to learn how to use those images in Kubernetes.
  • You’re an application developer and want to understand the Kubernetes core API objects to configure your application
  • You’re a system administrator and want to understand how to manage containerized applications in a cluster.
  • You’re a system administrator and want to run system daemons in your cluster like the same way you manage end-user application.
  • You’re a system administrator and want to understand how to monitor and collect logs in a Kubernetes cluster.

Prerequisites

  • Install minikube
  • Install kubectl
  • Create a deployment with kubectl run ghost --image=ghost
  • Scale that deployment, check the Pods
  • Check kubectl --help what can you do ?

Schedule

The timeframes are only estimates and may vary according to how the class is progressing.

DAY 1

Part I

  • Kubernetes intro (history, lineage, web resources)
  • Minikube (installation, basic usage, relation to other k8s deployment)

Part II

  • Using kubectl (interact with your Kubernetes cluster, introduce basic primitives: pods, deployments, replica set, services)
  • API resources and specification (json/yaml manifests)

Part III

  • Labels (the why and how about labels)
  • Services (how to expose applications to internet, service types, DNS)

DAY 2

Part I

  • Scaling, rolling updates and rollbacks
  • Ingress controllers (another way to expose apps using Ingress resources)

Part II

  • Volumes (define volumes in Pods)
  • DaemonSets (for admins who want to run system daemons via k8s)

Part III

  • Third-party resources (and why they're important)
  • Python client (custom controller 101, write a basic controller in Python)
