Shortly Cloud

URL shortener platform with a Rust redirect/API service, a Next.js web console, and production-grade Kubernetes manifests. It is tuned for high concurrency with Redis caching and PgBouncer pooling.

Repository layout

• backend: Rust API service (Axum + SQLx + Redis)
• frontend: Next.js marketing site + shortener console
• k8s: Kubernetes manifests for Postgres, PgBouncer, Redis, API, web, and ingress

Backend configuration

Set environment variables for the API service:

• DATABASE_URL: PgBouncer connection string
• REDIS_URL: Redis connection string
• BASE_URL: public base URL used for short links
• CACHE_TTL_SECONDS: cache TTL for redirects (default: 86400)
• CODE_LENGTH: short code length (default: 7)
• DB_MAX_CONNECTIONS: API pool size (default: 30)
• SERVICE_MODE: all | shorten | redirect (default: all)
• CLICK_FLUSH_INTERVAL_SECONDS: Redis click flush interval (default: 10)
• CLICK_FLUSH_BATCH_SIZE: batch size per DB flush (default: 1000)

Frontend configuration

• NEXT_PUBLIC_API_URL: API base URL exposed to the browser

Kubernetes quick start

1. Build and push images:

# Example tags
# shortly-api:latest
# shortly-web:latest

2. Apply manifests:

kubectl apply -f k8s/namespace.yaml
kubectl apply -f k8s/db-secret.yaml
kubectl apply -f k8s/app-config.yaml
kubectl apply -f k8s/postgres.yaml
kubectl apply -f k8s/pgbouncer.yaml
kubectl apply -f k8s/redis.yaml
kubectl apply -f k8s/api.yaml
kubectl apply -f k8s/redirect.yaml
kubectl apply -f k8s/web.yaml
kubectl apply -f k8s/ingress.yaml
kubectl apply -f k8s/networkpolicy.yaml

Notes

• Update k8s/db-secret.yaml and k8s/pgbouncer.yaml with your production credentials.
• Set k8s/app-config.yaml hostnames to match your DNS and TLS.
