Docker containers are a powerful tool for packaging, distributing, and managing applications. This tutorial will guide you through the basics of working with Docker containers.
Containers are lightweight, standalone executable packages that include everything needed to run a piece of software, such as the code, libraries, system tools, and runtime. They provide a consistent environment across different stages of development and deployment.
Before you can start working with Docker containers, you'll need to install Docker on your system. Follow the instructions for your operating system:
Here are some essential Docker commands to get you started:
docker pull <image>\: Download an image from a registry.docker run <image>\: Create and start a container from an image.docker ps\: List running containers.docker stop <container>\: Stop a running container.Docker images are the building blocks of containers. You can find pre-built images on Docker Hub or create your own.
To download an image, use the `docker pull` command:
docker pull ubuntu
To see all the images on your system, use the `docker images` command:
docker images
You can create a container from an image using the `docker run` command. Here's an example of running a simple Ubuntu container:
docker run -it ubuntu bash
This command starts an interactive shell inside the Ubuntu container.
Docker containers offer a flexible and efficient way to build, ship, and run applications. By following this tutorial, you've learned the basics of working with Docker containers and are ready to explore further.

Happy Dockering!
