Google Cloud Pubsub Rust Client Example

This project is an example of how to use the Google Cloud Pub/Sub client in a Rust application.

Project Overview

pubsub-client-rust is a sample application that demonstrates how to interact with Google Cloud Pub/Sub from a Rust application. It is designed to be deployed as a containerized application on Google Cloud Run.

Key Technologies

Language: Rust
Google Cloud Pub/Sub Client: google-cloud-pubsub
Web Framework: Hyper
Containerization: Docker
Deployment: Google Cloud Run
CI/CD: Google Cloud Build

Getting Started

This project uses a Makefile to simplify common development tasks.

Prerequisites

Initial Setup

Install Dependencies:
```
cargo build
```
Run the application locally:
```
make run
```
The server will start on port 8080.

Development Workflow

The Makefile provides targets for common development tasks.

Building the Project

Development Build:
```
make build
```
Release Build:
```
make release
```

Running Locally

make run

Code Quality

Formatting:
```
make format
```
Linting:
```
make clippy
```

Testing

make test

Deployment

Deployment is handled by Google Cloud Build and defined in cloudbuild.yaml.

Manual Deployment

To manually trigger a deployment, run:

make deploy

This command submits a build to Google Cloud Build, which will:

Build the Docker image (as defined in Dockerfile).
Push the image to Google Container Registry (GCR).
Deploy the new image to the cloudrun-rust service in the us-central1 region.

Deployment Process

Dockerfile: A multi-stage Dockerfile is used to create a minimal, secure production image.
1. Builder Stage: The Rust code is compiled in a rust builder image.
2. Final Stage: The compiled binary is copied to a minimal gcr.io/distroless/cc-debian12 image.
cloudbuild.yaml: This file defines the Cloud Build pipeline. It takes care of building, pushing, and deploying the container image.
