Deployment Basics

Deploying Rust applications requires understanding build processes, target platforms, and deployment environments.

Build Types

Development Build


BASH
cargo build
# Creates: target/debug/your_app

Fast compilation: Minimal optimizations
Debug symbols: Easier debugging
Larger binaries: Not optimized

Release Build


BASH
cargo build --release
# Creates: target/release/your_app

Optimized: Maximum performance
Smaller binaries: Stripped symbols
Slower compilation: More optimizations

Cross-Compilation

Rust supports cross-compilation for different platforms:


BASH
# Install target
rustup target add x86_64-unknown-linux-musl

# Build for Linux from Windows/Mac
cargo build --release --target x86_64-unknown-linux-musl

Deployment Targets

Linux Servers

Most common: Linux VPS, cloud instances
Static linking: Use musl target for portability
Systemd: Service management

Docker Containers

Portable: Run anywhere Docker runs
Isolated: Consistent environment
Scalable: Easy to scale horizontally

Cloud Platforms

AWS: EC2, ECS, Lambda
Google Cloud: Cloud Run, GKE
Azure: Container Instances, AKS
DigitalOcean: Droplets, App Platform

Production Checklist

Code Examples

Build Optimization

Optimizing Rust builds for production

RUST

fn main() {
    println!("Production build settings:");
    println!("- opt-level = 3: Maximum performance");
    println!("- lto = true: Better optimization across crates");
    println!("- codegen-units = 1: Slower compile, better optimization");
    println!("- strip = true: Smaller binary size");
}

Explanation:

Release builds with optimization settings produce fast, efficient binaries perfect for production blockchain nodes and backends.

Environment Configuration

Using environment variables for configuration

RUST

fn get_config() -> (String, u16) {
    let db_url = String::from("postgres:
    let port = 8080;
    (db_url, port)
}
fn main() {
    let (db_url, port) = get_config();
    println!("Database: {}", db_url);
    println!("Port: {}", port);
    println!("\nSet environment variables:");
    println!("export DATABASE_URL=postgres:
    println!("export PORT=3000");
}

Explanation:

Environment variables allow configuration without code changes. This is essential for deploying to different environments (dev, staging, production).

Exercises

Build Configuration

Create a Cargo.toml with release optimizations!

Easy

Starter Code:

RUST

# Cargo.toml
# Add [profile.release] section with:
# - opt-level = 3
# - lto = true
[package]
name = "my_blockchain"
version = "0.1.0"
# Add release profile here
