🚀 Docker + Ansible Automation Project

A complete 3-tier application deployed using Docker, Docker Compose, and Ansible.

📦 Architecture

Frontend (React + Vite) → Nginx Reverse Proxy → Backend (.NET 8 API) → MySQL Database
All components run in containers and deployment is automated with Ansible.

🐳 Docker Usage

Build Frontend Image

cd React-Frontend
docker build -t abdosaad0/frontend-react:latest .

Build Backend Image

cd ../DotNet-Backend
docker build -t abdosaad0/backend-dotnet-api:latest .

▶ Run with Docker Compose

docker compose up -d

Open the app:
http://localhost:8080

Check running containers:
docker compose ps

🔐 Vars Files

vars/main.yml

DOCKER_USERNAME: "abdosaad0" images:

• name: "{{ DOCKER_USERNAME }}/frontend-react" tag: "latest" path: "./React-Frontend"
• name: "{{ DOCKER_USERNAME }}/backend-dotnet-api" tag: "latest" path: "./DotNet-Backend"

vars/secrets.yml (before encryption)

DB_PASSWORD: "your-db-password" DOCKER_PASSWORD: "your-dockerhub-password-or-token"

Encrypt with: ansible-vault encrypt vars/secrets.yml

🤖 Ansible Deployment

Install collection: ansible-galaxy collection install community.docker --force

Run playbook: ansible-playbook -i inventory playbook.yml --ask-vault-pass

The playbook will:

• Login to Docker Hub
• Build and push both images
• Create db_password.txt
• Run docker compose
• Delete db_password.txt

📜 playbook Summary

Automates:

• Docker Hub login
• Building images
• Pushing images
• Creating DB password file
• Running docker compose
• Cleaning secrets

✅ Final Result

Frontend → http://localhost:8080
Backend runs internally on port 8080
MySQL initialized automatically
Full deployment using: ansible-playbook -i inventory playbook.yml --ask-vault-pass
