This repo will contain a collection small apps with docker configurations kubernetes manifests to be used as templates and example. The goal of this project is to make it easier for anyone to understand deployments with kubernetes.
Note that the below requirements are only required to run the examples defined in this repository in your own local environment. The example are not meant for production environments and should be used in development / testing / homelab environments.
All examples will use docker for containerization. Most application templating will be done using helm and deployments will use krane for easy to understand live results.
