⚙️ CI/CD Pipeline

• GitHub Actions runs on push or PR:

  • ✅ Lint & test Go code
  • 🐳 Build Docker image
  • 🚢 Push to DockerHub

• Example: .github/workflows/cicd.yaml

---

💻 Local Setup (Docker)

# Clone the repo
git clone https://github.com/nsahil992/googly-login
cd googly-login

# Copy .env.example and set values (never commit .env!)
cp .env.example .env

# Start app
docker compose up --build

---

☸️ Kubernetes Setup

# Apply Postgres manifests first
kubectl apply -f postgres-pvc.yaml -f postgres-secret.yaml -f postgres-service.yaml -f postgres-deployment.yaml -f postgres-pv.yaml -n googly-login

# Apply Googly manifests
kubectl apply -f googly-deployment.yaml -f googly-service.yaml -n googly-login

---

⛵ Helm Setup

# Install all components via Helm chart
helm install googly-login ./helm/ -n googly-login

---

🧱 Network Policies with Calico

kubectl apply -f calico-network-policy.yaml -n googly-login

---

🔐 Secrets Management

✅ .env is used for local development only and is never committed to GitHub ✅ Kubernetes Secrets are defined in postgres-secret.yaml (base64-encoded) 🔒 You must create secrets locally
