ci: build, push and deploy to personal cluster on push to master

- Gitea Actions workflow: build, push sha-tagged image, apply kustomize, wait for rollout with auto-rollback
- Deploy to personal-site namespace, served at jesseinit.dev with TLS
- Run container as non-root and bind to 0.0.0.0

-# Kubernetes Deployment Guide
+# Kubernetes deployment
 
-This directory contains all the necessary Kubernetes manifests to deploy the jesseinit portfolio application.
+The site runs on the personal k3s cluster in the `personal-site` namespace and is served at
+https://jesseinit.dev (`www.` redirects to the apex). TLS comes from cert-manager (`letsencrypt-prod`).
 
-## Prerequisites
+## How deploys work
 
-- Kubernetes cluster (local or cloud)
+`.github/workflows/deploy.yml` (run by Gitea Actions) on every push to `master`:
-- kubectl CLI installed and configured
-- Docker for building the image
-- (Optional) kustomize for managing configurations
 
-## Files Overview
+1. **Build site**: `npm ci && npm run build`, and renders the kustomization to catch manifest errors.
+2. **Build and push image**: `tea.jesseinit.dev/jesseinit/personal-site:sha-<commit>` and `:latest`.
+3. **Deploy**: pins `newTag` in `kustomization.yaml` to `sha-<commit>`, runs `kubectl apply -k k8s/`,
+   waits for the rollout, and rolls back automatically if it fails.
 
-- `deployment.yaml` - Kubernetes Deployment with 2 replicas, health checks, and resource limits
+Pull requests run step 1 only. Old images are cleaned up by the nightly `gitea-package-prune` cronjob.
-- `service.yaml` - ClusterIP Service exposing the application on port 80
-- `ingress.yaml` - Ingress resource for external access (requires ingress controller)
-- `configmap.yaml` - ConfigMap for environment variables
-- `kustomization.yaml` - Kustomize configuration for easy deployment management
 
-## Quick Start
+### Required secrets (repo or `production` environment in Gitea)
 
-### 1. Build the Docker Image
+| Secret           | Value                                                 |
+| ---------------- | ----------------------------------------------------- |
+| `REGISTRY_TOKEN` | Gitea token with `write:package` for `jesseinit`      |
+| `KUBE_CONFIG`    | base64-encoded kubeconfig for the personal cluster    |
+
+## Files
+
+- `namespace.yaml`: `personal-site` namespace
+- `deployment.yaml`: 2 replicas, zero-downtime rolling updates, non-root, health checks
+- `service.yaml`: ClusterIP on port 80 → container port 3000
+- `ingress.yaml`: nginx ingress + TLS for `jesseinit.dev` / `www.jesseinit.dev`
+- `configmap.yaml`: optional environment variables
+- `kustomization.yaml`: ties it together and sets the image
+
+## Manual operations
 
 ```bash
-# Build the image
+kubectl --context personal-cluster -n personal-site get pods,ingress,certificate
-docker build -t jesseinit-portfolio:latest .
+kubectl --context personal-cluster -n personal-site logs -l app=jesseinit-portfolio -f
+kubectl --context personal-cluster -n personal-site rollout undo deployment/jesseinit-portfolio
 
-# If using a registry, tag and push
+# Deploy by hand (uses :latest)
-docker tag jesseinit-portfolio:latest <your-registry>/jesseinit-portfolio:latest
+kubectl --context personal-cluster apply -k k8s/
-docker push <your-registry>/jesseinit-portfolio:latest
 ```
-
-### 2. Update Image Reference (if using a registry)
-
-Edit `k8s/kustomization.yaml` and update the image reference:
-
-```yaml
-images:
-  - name: jesseinit-portfolio
-    newName: <your-registry>/jesseinit-portfolio
-    newTag: latest
-```
-
-### 3. Deploy to Kubernetes
-
-#### Option A: Using kubectl
-
-```bash
-# Apply all manifests
-kubectl apply -f k8s/
-
-# Verify deployment
-kubectl get pods -l app=jesseinit-portfolio
-kubectl get svc jesseinit-portfolio
-kubectl get ingress jesseinit-portfolio
-```
-
-#### Option B: Using Kustomize
-
-```bash
-# Deploy using kustomize
-kubectl apply -k k8s/
-
-# Or build and preview first
-kubectl kustomize k8s/ | kubectl apply -f -
-```
-
-### 4. Configure Ingress (Optional)
-
-Edit `k8s/ingress.yaml` to match your setup:
-
-1. Update the `host` field with your domain
-2. Set the correct `ingressClassName` (nginx, traefik, etc.)
-3. Uncomment TLS section if using HTTPS
-4. Add appropriate annotations for your ingress controller
-
-Example for NGINX with cert-manager:
-
-```yaml
-annotations:
-  nginx.ingress.kubernetes.io/ssl-redirect: "true"
-  cert-manager.io/cluster-issuer: "letsencrypt-prod"
-```
-
-### 5. Add Environment Variables (Optional)
-
-Edit `k8s/configmap.yaml` to add any required environment variables:
-
-```yaml
-data:
-  API_URL: "https://api.example.com"
-  NEXT_PUBLIC_SITE_URL: "https://jesseinit.com"
-```
-
-## Local Development with Minikube
-
-```bash
-# Start minikube
-minikube start
-
-# Build image in minikube's Docker daemon
-eval $(minikube docker-env)
-docker build -t jesseinit-portfolio:latest .
-
-# Deploy
-kubectl apply -k k8s/
-
-# Access the application
-minikube service jesseinit-portfolio
-```
-
-## Monitoring
-
-### Check Pod Status
-
-```bash
-kubectl get pods -l app=jesseinit-portfolio
-kubectl logs -l app=jesseinit-portfolio -f
-kubectl describe pod <pod-name>
-```
-
-### Check Service
-
-```bash
-kubectl get svc jesseinit-portfolio
-kubectl describe svc jesseinit-portfolio
-```
-
-### Port Forward for Local Testing
-
-```bash
-kubectl port-forward svc/jesseinit-portfolio 8080:80
-# Access at http://localhost:8080
-```
-
-## Scaling
-
-```bash
-# Scale to 3 replicas
-kubectl scale deployment jesseinit-portfolio --replicas=3
-
-# Or edit deployment.yaml and reapply
-```
-
-## Updating the Application
-
-```bash
-# Build new image with new tag
-docker build -t jesseinit-portfolio:v2 .
-docker push <your-registry>/jesseinit-portfolio:v2
-
-# Update the image
-kubectl set image deployment/jesseinit-portfolio portfolio=<your-registry>/jesseinit-portfolio:v2
-
-# Or update kustomization.yaml and reapply
-kubectl apply -k k8s/
-```
-
-## Troubleshooting
-
-### Pods not starting
-
-```bash
-kubectl describe pod <pod-name>
-kubectl logs <pod-name>
-```
-
-### Service not accessible
-
-```bash
-kubectl get endpoints jesseinit-portfolio
-kubectl describe svc jesseinit-portfolio
-```
-
-### Image pull errors
-
-If using a private registry, create an image pull secret:
-
-```bash
-kubectl create secret docker-registry regcred \
-  --docker-server=<your-registry> \
-  --docker-username=<username> \
-  --docker-password=<password> \
-  --docker-email=<email>
-```
-
-Then add to `deployment.yaml`:
-
-```yaml
-spec:
-  imagePullSecrets:
-  - name: regcred
-```
-
-## Resource Management
-
-The deployment includes default resource requests and limits:
-
-- Requests: 128Mi memory, 100m CPU
-- Limits: 512Mi memory, 500m CPU
-
-Adjust these in `deployment.yaml` based on your application's needs.
-
-## Cleanup
-
-```bash
-# Delete all resources
-kubectl delete -k k8s/
-
-# Or delete individually
-kubectl delete -f k8s/
-```
-
-## Production Considerations
-
-1. **Use a specific image tag** instead of `latest` for better version control
-2. **Set up HorizontalPodAutoscaler** for automatic scaling
-3. **Configure persistent storage** if needed (for logs, cache, etc.)
-4. **Add network policies** for security
-5. **Set up monitoring** with Prometheus/Grafana
-6. **Configure TLS/SSL** certificates for HTTPS
-7. **Use secrets** for sensitive data instead of ConfigMaps
-8. **Implement resource quotas** and limit ranges
-9. **Set up backup and disaster recovery** procedures
-10. **Use namespace isolation** for multi-environment deployments
