Dockerizing Python Code for Tic-Tac-Toe Game

This project demonstrates how to Dockerize a simple Python-based Tic-Tac-Toe game. By the end of this guide, you'll have a containerized Python application that you can run anywhere using Docker.

Clone Repo

To get started, clone the repository and navigate into the project folder:

git clone https://github.com/YogitaBadhe/Dockerizing_python_Code.git
cd Dockerizing_python_Code

Prerequisites

Before you begin, ensure that you have the following installed:

1. Docker

Ensure that Docker is installed on your system. If not, you can install Docker using the following command:

sudo yum install docker -y

2. Git

You need Git to clone the repository. If you don't have Git installed, use:

sudo yum install git -y

3. Python

You will need Python installed to test the Tic-Tac-Toe game. Install Python if it's not already on your system:

sudo yum install python -y

Steps to Dockerize Python Code

1. Setup Docker

Start the Docker service and enable it to start on boot:

sudo systemctl start docker
sudo systemctl enable docker

Verify your Docker installation:

docker --version

2. Configure Git

Configure your Git user details (optional but recommended):

git config --global user.name "YogitaBadhe"
git config --global user.email "[email protected]"

3. Create and Test Python Script

Create the Python script for your Tic-Tac-Toe game:

sudo touch tic-tac-toe.py
sudo nano tic-tac-toe.py

Paste your Python code into the file, then test it locally:

python3 tic-tac-toe.py

4. Create Dockerfile

Create a Dockerfile in the root of your project directory:

touch Dockerfile
sudo nano Dockerfile

Add the following content to the Dockerfile:

# Use the official Python image from the Docker Hub
FROM python:3.8-slim

# Set the working directory in the container
WORKDIR /app

# Copy the current directory contents into the container at /app
COPY . /app

# Run tic-tac-toe.py when the container launches
CMD ["python", "tic-tac-toe.py"]

5. Build and Push Docker Image

1. Log in to Docker Hub (if you haven’t already):

   sudo docker login

2. Build the Docker image:

   sudo docker build -t ybadhe/pythonproject .

3. Verify the Docker image is built:

   sudo docker images

4. Push the Docker image to Docker Hub:

   sudo docker push ybadhe/pythonproject

6. Run Docker Container

1. Run your Docker container:

   sudo docker run ybadhe/pythonproject

2. List all running Docker containers:

   sudo docker ps -a

---

Interacting with the Game

Once the container is running, you'll interact with the Tic-Tac-Toe game through the terminal. The game will prompt you to enter row and column numbers for player moves (e.g., 0 1 for row 0, column 1).

Sample Gameplay:

Tic-Tac-Toe Game
| X |   |   |
---------
|   | O |   |
---------
|   |   | X |
Player X, enter row and column (0-2): 1 1
Player O, enter row and column (0-2): 0 0
...

7. Stopping the Docker Container

To stop the container, use the following command:

sudo docker stop <container_id>

You can get the <container_id> by running:

sudo docker ps -a

---

Conclusion

By following these steps, you have successfully Dockerized a Python Tic-Tac-Toe game. You can now run the game as a Docker container on any machine that supports Docker.

If you encounter any issues, please open an issue on the repository, and I'll assist you as soon as possible.
