Docker is a powerful platform for developing, shipping, and running applications in containers. Containers are lightweight, portable, and can run on any system that supports Docker. In this tutorial, we will guide you through running a Python script inside a Docker container using the docker run command.
Before you begin, make sure you have Docker installed on your system. You can download Docker from the official website.
Docker images are pre-packaged environments that include all the necessary dependencies for running an application. In this case, we'll use the official Python image from Docker Hub.
Open a terminal and run the following command to pull the Python 3 image:
This command downloads the latest Python 3 image from Docker Hub to your local machine.
Now, let's create a simple Python script that we'll run inside the Docker container. Create a file named app.py with the following content:
Now that we have our Python script and the Python Docker image, we can run the script inside a Docker container. Use the following command in the terminal:
Replace /path/to/your/app.py with the actual path to your Python script. If the script is in the current directory, you can use the following command:
This command mounts the current directory ($(pwd)) into the /usr/src/app directory inside the container and runs the Python script.
Congratulations! You've successfully run a Python script inside a Docker container. Docker provides a consistent environment for your applications, making it easier to manage dependencies and deploy your code across different environments.
