briandenicola/kubernetes

A repository of various K8S setups and configurations

Overview

A set of example Kubernetes clusters with a focus on Azure AKS and CNCF projects. Most of these examples require Terraform so requires a working knowledge of that tooling and how it is used with Azure/GCP. This repository also contains a few applications that can be used to demostrate various capabilities

Tooling

• Terraform
• Azure Cli
• Task
