# 🚀 Optimized Dockerfiles Collection
2+
3+
This repository contains a curated set of **production-ready**, **DevOps-focused**, and **highly optimized Dockerfiles** for different kinds of applications and stacks.
4+
The purpose is to provide learning resources and ready-to-use examples that demonstrate **best practices for containerization**, **image optimization**, and **production deployment**.
5+
6+
## 🎯 Repository Goals
7+
8+
- Provide **real-world Dockerfile examples** for multiple technologies.
9+
- Demonstrate **multi-stage builds**, **image minimization**, and **secure production setups**.
10+
- Compare **optimized** vs **non-optimized** Dockerfiles.
11+
- Offer **DevOps patterns** for CI/CD, caching, static serving, and deployment.
12+
- Serve as a reference for building your own production-grade Docker images.

## 🐳 Docker Philosophy Used in This Repo
55+
56+
This repository follows production-grade principles:
57+
58+
### ✔ Multi-Stage Builds
59+
Reduce final image size by separating build and runtime stages.
60+
61+
### ✔ Minimal Base Images
62+
Using `alpine`, `scratch`, or distroless where applicable.
63+
64+
### ✔ Static Asset Serving
65+
Frontend projects use **Nginx** instead of `vite preview`.
66+
67+
### ✔ Security Hardening
68+
- Non-root users where possible
69+
- Read-only filesystem
70+
- Minimal OS footprint
71+
72+
### ✔ CI/CD Friendly
73+
All examples are built to:
74+
75+
- Be cache efficient
76+
- Work well with GitHub Actions
77+
- Push easily to Docker Hub
78+
79+
---
80+
81+
## 🔄 CI/CD Integration
82+
83+
Soon you'll find:
84+
85+
- GitHub Actions templates for:
86+
- Building Docker images
87+
- Tagging releases
88+
- Pushing to Docker Hub
89+
- Multi-platform builds (`amd64`, `arm64`)
90+
91+

92+
93+

96+
97+
- Additional optimized Dockerfiles
98+
- Example microservices
99+

# ⚛️ React + Vite — Production Docker Setup
22

3-
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
3+
This project demonstrates how to containerize a **Vite + React** application using a **fully optimized production-grade Dockerfile**.
4+
It also includes a **non-optimized version** for comparison to help understand the DevOps improvements and performance benefits.

5-
Currently, two official plugins are available:

7-
- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
8-
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh

## 🎯 Purpose of This Example
99

10-
## React Compiler
10+
- Show best practices for building production-ready frontend images.
11+
- Compare optimized vs non-optimized Docker builds.
12+
- Teach static asset serving with **Nginx**, Brotli, and Gzip.
13+
- Provide DevOps-friendly build patterns for CI/CD pipelines.

The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).

If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the [TS template](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-react-ts) for information on how to integrate TypeScript and [`typescript-eslint`](https://typescript-eslint.io) in your project.

## 🚀 Build the optimized image
31+

docker build -t react-vite-app:prod .

## 🏗️ Optimized Production Docker Architecture
39+
40+
The optimized Dockerfile uses:
41+
42+
- ✔ Multi-stage build
43+
44+
- Stage 1: Node (build React app)
45+
46+
- Stage 2: Nginx (serve static files)
47+
48+
- ✔ Alpine-based images
49+
50+
- Small and secure.
51+
52+
- ✔ Static file serving via Nginx
53+
54+
- Extremely fast
55+
56+
- Brotli & gzip
57+
58+
-Aggressive caching for /assets
59+
60+
- ✔ Minimal final image
61+
62+
- Only contains the built static files + Nginx.
63+
64+
- ✔ DevOps advantages
65+
66+
- Smaller images → faster CI/CD
67+
68+
- Deterministic builds
69+
70+
- CDN-friendly caching
71+
72+
- Better security posture
