Exploring k8s with minikube on codespaces

Kubernetes: Managing Containers at Scale

Background

This repo will contain examples to learn:

• Creating shared volume mounts for Databases
• Creating highly available (HA) websites using Deployments
• Deploying basic Services to communicate with HA pods
• Calico Networking for Pod-to-Pod communication
• Common K8s troubleshooting
• Basic K8s DevOps with Tekton
• Role-Based Access Control (RBAC) for cluster/user resource control

We will be using minikube on GitHub Codespaces to explore K8s. To learn how to setup your codespace environment, please reference this document.
