#How to Deploy an Application

A Salvo project compiles into an executable file. To deploy, simply upload this executable along with its dependent static resources to your server.

For Rust-based projects, there is also a very simple deployment platform: shuttle.rs. Shuttle provides support for Salvo projects. For details, please refer to the official documentation.

#Docker Deployment

You can also deploy Salvo applications using Docker. Below is a basic Dockerfile example that you can adjust according to your project's requirements:

# Build stage
FROM rust:slim AS build
WORKDIR /app

# Copy dependency files first to build dependencies (utilizing cache layers)
COPY Cargo.toml Cargo.lock ./
RUN mkdir src && \
    echo 'fn main() { println!("Placeholder"); }' > src/main.rs && \
    cargo build --release

# Copy actual source code and build the application
COPY src ./src/
RUN touch src/main.rs && \
    cargo build --release

# Runtime stage using a minimal base image
FROM debian:bookworm-slim
RUN apt-get update && \
    apt-get install -y --no-install-recommends ca-certificates && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/*

# Create a non-root user to run the application
RUN useradd -ms /bin/bash appuser
USER appuser
WORKDIR /app

# Copy the binary from the build stage
COPY --from=build /app/target/release/your_app_name ./app

# Set the container startup command
CMD ["./app"]

#Usage Instructions

1. Save the above Dockerfile in your project's root directory
2. Adjust your_app_name to match your actual binary filename
3. If your application requires static files (such as templates, CSS, JS, etc.), add the corresponding COPY commands
4. If your application needs environment variable configuration, use the ENV directive
5. Build the Docker image:

   docker build -t your-app-name .
6. Run the container:

   docker run -p 5800:5800 your-app-name

Please adjust the port number and other configurations according to your application's actual requirements.
