CI Pipeline

GitHub Actions automatically:

1. installs dependencies
2. builds the Next.js application
3. builds the Docker image
4. pushes the image to GitHub Container Registry

Example image:

ghcr.io/intscription/gravity-log-web:latest

---

Kubernetes Deployment

The application is deployed using Kubernetes with:

• Deployment
• Service
• Secrets

Example deployment:

kubectl apply -f infra/kubernetes/

---

Local Deployment

Deploy the latest container image with one command:

./infra/scripts/release.sh

This script:

1. pushes code to GitHub
2. waits for CI to build the Docker image
3. deploys the new container to Kubernetes

---

Running Locally

Start the web app

cd web
npm install
npm run dev

---

Run with Docker

docker compose up --build

---

Kubernetes Deployment

minikube start
kubectl apply -f infra/kubernetes/

---

Environment Variables

Create .env.local inside web/:

NEXT_PUBLIC_SUPABASE_URL=
NEXT_PUBLIC_SUPABASE_ANON_KEY=

---

Future Improvements

• Kubernetes Ingress
• Health probes
• GitOps deployment
• Monitoring (Prometheus + Grafana)
