Look inside

In this liveProject, you’ll properly configure a Kubernetes app so that it’s secure and resilient in production. Working with a previously deployed application, you’ll set up the app to read configuration settings from the cluster so you can use the same Docker images in test and production. Extend your app’s specifications to activate Kubernetes’s self-healing, defend against attackers with security controls, and run a replicated database in containers. Once you’re finished, you’ll have a securely deployed demo app that’s resilient against whatever production throws at it.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.

project author

Elton Stoneman
Elton is a freelance consultant and trainer. He spent most of his career designing and building large enterprise applications, until he discovered the container revolution, joined Docker, and worked with the team for three fast and furious years. Now he helps people break up those old enterprise apps and build new cloud-native apps - and run them all in Docker and Kubernetes. He speaks at conferences and runs training courses all around the world, writes books and video courses, and helps organizations at every stage in their container and cloud journey. Elton’s a 12-time Microsoft MVP and a Docker Captain.

prerequisites

This liveProject is for improving Kubernetes users at the start of their journeys. You should know a few core Kubernetes concepts like the Kubectl command line, and the most common API resources. To begin this liveProject, you will need to be familiar with the following:

TOOLS
  • Basics of Docker
  • Basics of Kubernetes
  • A text editor with support for YAML files
  • Basics of a CLI such as PowerShell or Linux shells
TECHNIQUES
  • Discovering application configuration requirements
  • Debugging failing containers and Pods
  • Securing Linux applications

you will learn

In this liveProject, you’ll learn important configuration techniques to ensure that your Kubernetes apps are reliable and secure enough to take into production.

  • Adding container probes to your Pods to test application health and repair failures
  • Testing the health of different application types, with HTTP, TCP, and command probes
  • Securing applications by restricting access to the Kubernetes API from within Pod containers
  • Applying security controls to Pods to limit the capabilities of attackers
  • Using storage volumes to persist data outside of the Pod lifecycle and keep data safe
  • Modeling stateful apps which replicate data across primary and secondary servers
