Workshop: [SOLD OUT] Kubernetes Intensive Course

Location: Westminster, 4th flr.

Duration: 9:00am - 4:00pm

Day of week: Friday

Level: Intermediate

Key Takeaways

  • First contact with a Kubernetes cluster
  • Running containers, pods, deployments
  • Connecting apps with services
  • Understanding and using YAML manifests
  • Managing workloads with labels and selectors
  • Safe rollouts and rollbacks
  • App configuration

Prerequisites

To make the most out of this workshop, you should be comfortable with the UNIX command line (be able to SSH into a remote machine, navigate directories, edit files with `vi` or a similar editor), and have basic knowledge of containers. It's not necessary to be a Docker expert, but ideally, you'll have already built and run a container image (for instance with `docker build` and `docker run`).

If you have zero knowledge of containers, the "Docker Intensive Course" workshop will teach you everything you need (and some more).

You do not need to install Kubernetes on your local machine: we will execute all the exercises on remote Kubernetes clusters, provided for the duration of the workshop.

More talks on:

You've started to "containerize" your applications by writing a Dockerfile or two, and now you want to run your containers in a cluster. But Kubernetes is quite different from Docker: the smallest unit of deployment is not a container, but a *pod*; pods are accessed through specialized load balancers called *services*; there are *labels* and *selectors* everywhere; and everything is created by expressing desired state with YAML, lots of YAML.

In this hands-on workshop, we will learn about Kubernetes and its key concepts, both in theory (we will become familiar with all the things evoked in the previous paragraph) and in practice (we will know how to use them to deploy and scale our applications).

Kubernetes has the reputation of being a complex system with a steep learning curve. We will see that it is, indeed, a complex system, but that it is possible to tame its most essential features in just a few hours.

This is what we will cover:

Kubernetes overview

  • Orchestration concepts
  • The API and control plane
  • Nodes, Pods, Services
  • Declarative vs imperative

First contact

  • Using kubectl
  • Running containers on k8s
  • From Pods to Deployments
  • Cronjobs and other resources
  • Accessing logs

Connecting containers

  • Kubernetes network model
  • The different Service types
  • Exposing containers

Running applications

  • Shipping images
  • Deploying with YAML
  • Scaling our demo app

Managing containers

  • Labels and selectors
  • Rolling updates
  • Namespaces  

...And some more 

  • Ingress and HTTP services
  • Volumes
  • Configuration management

This workshop is for developers, system administrators, and architects alike: anyone who needs to interact with a Kubernetes cluster, or who wants to understand practical Kubernetes concepts in order to design scalable applications.

Speaker: Jérôme Petazzoni

Staff Container & Infrastructure Engineer @enixsas

Jérôme was part of the team that built, scaled, and operated the dotCloud PAAS, before that company became Docker. He worked seven years at the container startup, where he wore countless hats and ran containers in production before it was cool. He loves to share what he knows, which led him to give hundreds of talks and demos on containers, Docker, and Kubernetes. He trained thousands of people to deploy their apps in confidence on these platforms, and continues to do so as an independent consultant. He values diversity, and strives to be a good ally, or at least a decent social justice sidekick. He also collects musical instruments and can arguably play the theme of Zelda on a dozen of them.
