Learning Kubernetes

A guide to administering and using Kubernetes clusters declaratively

⚠️ This is a work in progress.

Examples of clusters and Helm charts / releases have been moved to https://github.com/ilyasotkov/exekube.

⚗️ Labs

Lab 0: Background information

• What is Kubernetes? What are the benefits of using Kubernetes?
• Compare Kubernetes to deploying software directly onto bare metal or virtual machines
• Goals and principles of this Kubernetes guide

Lab 1: Create and upgrade a Kubernetes cluster

📋 Lab Overview: How do I create a Kubernetes cluster and how do I maintain it?

• Create a Kubernetes cluster
• Upgrade a Kubernetes cluster
• Destroy a Kubernetes cluster

Lab 2: Get your cluster ready for production

📋 Lab Overview: How do I turn a bare Kubernetes installation into a production-ready cluster?

• Authentication: allow access to cluster resources
• Authorization: limit access to cluster resources
• Persistent storage
• Networking, load balancing, and ingress management
• Monitoring and alerting
• Continous Integration (CI) tools

Lab 3: Deploy software onto your cluster

📋 Lab Overview: What's the best way to consume Kubernetes cluster resources?

• Create a Helm chart
• Install a Helm chart
• Manage Helm releases

📌 Goals

• Learn to set up and administer Kubernetes clusters of any scale
• Establish a smooth declarative workflow for deploying containerized applications and services to Kubernetes clusters
• Get familiar with the Kubernetes Docs at https://kubernetes.io/docs
• Read real-world case studies
