# Kubernetes Development
These configs and scripts attempt to simplify spinning up a kubernetes cluster
for development and testing purposes. It leverages [k3d](https://k3d.io) to create
a [k3s](https://k3s.io) cluster in Docker. Homepage can then be deployed either via
the `k3d-deploy.sh` script, or [tilt](https://tilt.dev) can be used to spin up a
local CI loop that will automatically update the deployment.
All the commands in the document should be run from the `k3d` directory.
## Requisite Tools
| Tool | Description |
|-------------------------------------------------------------|----------------------------------------------------------|
| [docker](https://docker.io) | Docker container runtime |
| [kubectl](https://kubernetes.io/releases/download/#kubectl) | Kubernetes CLI |
| [helm](https://helm.sh) | Kubernetes package manager |
| [k3d](https://k3d.io) | Kubernetes on Docker - used to create the cluster |
| [k9s](https://k9scli.io) | (Optional) Command line view for kubernetes cluster |
| [tilt](https://tilt.dev) | (Optional) Local CI loop for kubernetes deployment |
| [direnv](https://direnv.net/) | (Optional) Automatically loads `kubeconfig` via `.envrc` |
## One-off Test Deployments
Create a cluster:
```sh
./k3d-up.sh
```
Build and deploy:
```sh
./k3d-deploy.sh
```
Open the Homepage deployment:
```sh
xdg-open http://homepage.k3d.localhost:8080/
```
## Continuous Deployment
Create a cluster:
```sh
./k3d-up.sh
```
Kick off tilt:
```sh
tilt up
```
Press space bar to open the tilt web UI, which is quite informative.
Open the Homepage deployment:
```sh
xdg-open http://homepage.k3d.localhost:8080/
```
