🐳 Optimize Dockerfile with Multi-Stage Build

[arcane-engine]

This pull request optimizes the Dockerfile by implementing a multi-stage build process. This change significantly reduces the final image size and enhances deployment speed, making the application more efficient and faster to deploy.

---

Dockerfile Optimization

• Update the Dockerfile to use a multi-stage build.
• Reduce the final image size by separating the build and runtime environments.
• Improve deployment speed by minimizing the image size.

Environment Setup

• Set environment variables PYTHONDONTWRITEBYTECODE and PYTHONUNBUFFERED for both build and final stages.

File Management

• Copy only necessary files from the builder stage to the final stage to ensure a lean runtime environment.

You can view the changes in the Dockerfile.

Multi-Stage Builds
Multi-stage builds in Docker allow you to use multiple FROM statements in your Dockerfile. Each FROM instruction starts a new stage of the build. You can selectively copy artifacts from one stage to another, which helps in creating smaller and more efficient Docker images. This is particularly useful for separating build-time dependencies from runtime dependencies, thus reducing the final image size and improving deployment efficiency. 🚀✨
