## Usage
### Production
### Kubernetes
#### Docker
#### Requirements
- Local or remote Kubernetes cluster, i.e. [`minikube`](https://kubernetes.io/docs/tasks/tools/install-minikube/)
- [`kubectl`](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
- [`skaffold`](https://skaffold.dev/)
#### Production
```bash
# Deploy the Traefik Ingress
kubectl apply -f https://raw.githubusercontent.com/containous/traefik/v1.7/examples/k8s/traefik-rbac.yaml
kubectl apply -f https://raw.githubusercontent.com/containous/traefik/v1.7/examples/k8s/traefik-ds.yaml
# Replace ${IP} with your Ingress' IP
echo "${IP} dev.lemmy.local" >> /etc/hosts
```
```bash
skaffold run -p lemmy--prod
```
Now go to http://dev.lemmy.local.
#### Development
```bash
skaffold dev -p lemmy--dev
```
Now go to http://localhost:4444. It automatically proxies to localhost, both if the cluster is local or remote; it also hot-reloads the UI and automatically recompiles and restarts the server.
### Docker
Make sure you have both docker and docker-compose installed.
