weather-rust

A simple, containerized Rust web server for fetching weather information, designed for deployment on Google Cloud Run.

Overview

This project provides a basic "Hello, World!" style web application written in Rust. It serves as a template and example for building and deploying a minimal, secure, and efficient Rust application on Google Cloud Run using Docker and Google Cloud Build.

Technologies Used

• Language: Rust
• Web Framework: Hyper
• Containerization: Docker
• Deployment: Google Cloud Run
• CI/CD: Google Cloud Build

Getting Started

A Makefile is included to simplify common development tasks.

Prerequisites

Before you begin, ensure you have the following installed:

• Rust Toolchain
• Docker
• Google Cloud SDK

Initial Setup

Clone the repository and install the necessary dependencies:

cargo build

Development Workflow

The following commands are available through the Makefile.

Building the Project

• Development Build:

  make build
  

• Release Build (optimized for production):

  make release
  

Running Locally

To start the server on http://localhost:8080:

make run

Code Quality

• Format the code:

  make format
  

• Lint the code with Clippy:

  make clippy
  

Testing

Run the test suite:

make test

Deployment

Deployment is automated via Google Cloud Build, as defined in cloudbuild.yaml. The process uses a multi-stage Dockerfile to build a minimal, secure production image based on gcr.io/distroless/cc-debian12.

To manually trigger a deployment, run:

make deploy

This command will:

1. Submit a build to Google Cloud Build.
2. Build and push the Docker image to Google Container Registry (GCR).
3. Deploy the new image to the cloudrun-rust service in the us-central1 region.
