# Deploy with K8s
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.
## Development requirements for this repo
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.
1. [Docker](https://docs.docker.com/engine/install/)
2. [Minikube](https://minikube.sigs.k8s.io/docs/start/?arch=%2Fmacos%2Fx86-64%2Fstable%2Fbinary+download)
3. [kubectl](https://kubernetes.io/docs/tasks/tools/)
4. [Helm](https://helm.sh/docs/intro/install/)
5. [Krane](https://github.com/Shopify/krane)
6. `golang / python / nodejs / etc... (see ./src/*/README.md)`
## Building and deploying
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.
## Example build and deploy
