Task Manager (Flask + Docker + AWS EC2)

A full-stack Flask Task Manager web application containerized with Docker, deployed on Amazon EC2, and integrated with an auto-creating database using SQLAlchemy.

---

Features

• Flask web app with user authentication & task management
• MySQL / MariaDB backend
• Dockerized for easy deployment
• Auto-database creation on startup
• Nginx reverse proxy configuration
• Compatible with AWS EC2 (Amazon Linux)

---

Deployment Steps on AWS EC2 (Amazon Linux)

1️ Launch EC2 Instance

1. Go to [AWS EC2 Console]
2. Launch an instance with:
   • Amazon Linux
   • t2.micro (Free Tier)
   • Port 22 (SSH), 80 (HTTP), 443 (HTTPS) open in Security Group
3. Connect via SSH:

   ssh -i your-key.pem ec2-user@your-ec2-public-ip

---

2️ Update & Install Dependencies

sudo yum update -y
sudo yum install -y git docker

Install Docker Compose:

sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose version

Enable Docker service:

sudo systemctl start docker
sudo systemctl enable docker

3️ Clone the Project from GitHub

git clone https://github.com/ChetanMuli/Task-manager-Docker-Python-MySQL.git
cd Task-manager-Docker-Python-MySQL

4️ Environment Configuration

Copy .env.example to .env if required:

cd app
cp .env.example .env

Kindly read .env or docker-compose.yml for database details (Password,User,DB Name)

Adjust DB credentials or secret keys as needed.

---

5️ Build and Run Containers

Go back to the main folder where docker-compose.yml exists:

cd ..
docker-compose up -d --build

This will:

• Build all Docker images
• Start containers (Flask app, database, Nginx)
• Automatically create database tables

---

6️ Verify Deployment

Check running containers:

docker ps

View logs:

docker logs <container_name>

Visit in browser:

http://<EC2-Public-IP>

You should see your Task Manager web app

---

7️ Common Commands

Stop containers:

docker-compose down

Rebuild (after code changes):

docker-compose up -d --build

Check database:

docker exec -it <db-container-name or ID> bash
mysql -u <taskuser> -p

---

Automatic Database Creation

It happens automatically when the container runs.
