Rust Development Environment

Rust Development Environment

A full Rust development stack without the setup tax. cargo-watch monitors your source for changes and triggers recompiles automatically, while Postgres and Redis are ready to connect from your first line of code.

What's Included

• Rust (stable, latest) with cargo-watch for live reloading on file changes
• Postgres 16 for persistent storage
• Redis 7 for caching and session state
• Volume-mounted ./src — edit on your host, recompile in the container
• Cargo registry cache volume to avoid re-downloading crates on restart

Developer Experience

• cargo-watch -x run starts on container up — no extra command needed
• Source directory mounted at /app inside the container for accurate error paths
• Cargo home cached in a named volume — dependencies survive docker compose down
• Environment variables for DATABASE_URL and REDIS_URL pre-set for sqlx and deadpool-redis

What You Get

• docker-compose.yml — all three services with dependency ordering
• Dockerfile — multi-stage: dev stage for fast iteration, release stage for production builds
• src/main.rs — minimal starter that connects to Postgres and Redis on startup
• Cargo.toml — pre-seeded with tokio, sqlx, redis, and dotenvy
• .env.example, .gitignore, README.md

Service URLs

• App: http://localhost:8080
• Postgres: localhost:5432
• Redis: localhost:6379
