Running python program on docker

Docker is a powerful platform for developing, shipping, and running applications in containers. Containers provide a consistent and isolated environment for your applications, making it easier to manage dependencies and ensure consistency across different environments. In this tutorial, we'll walk you through running a Python program inside a Docker container.
Before you begin, make sure you have the following installed on your system:
Let's start by creating a simple Python program that we will run inside the Docker container. For this example, we will create a Python script that prints "Hello, Docker!" to the console.
Create a file named hello.py with the following content:
A Dockerfile is a script that contains instructions for building a Docker image. It defines the base image, adds files, sets environment variables, and specifies how the container should run. Create a file named Dockerfile (no file extension) in the same directory as your Python script with the following content:
In this Dockerfile:
Open your terminal and navigate to the directory containing your Python script and Dockerfile. Run the following command to build the Docker image:
Docker will now create an image based on your Dockerfile.
After the image is built, you can run a Docker container using the following command:
You should see the output "Hello, Docker!" printed to the console.
In this tutorial, you learned how to run a Python program inside a Docker container. Docker allows you to package your application and its dependencies into a consistent and portable container, making it easy to deploy your Python applications across different environments.
Feel free to modify the Python program or the Dockerfile to suit your specific needs. This is just the beginning of what you can do with Docker, and it's a powerful tool for managing and scaling your applications.
