Docker is an open-source platform that allows developers to run applications in containers. Containers are a lightweight alternative to virtual machines and allow developers to develop, test, and deploy applications faster. Docker packages software into standardized units called containers that contain everything needed to run the software, including libraries, system tools, code, and runtime. With Docker, you can quickly deploy and scale applications in any environment and be confident that your code will run. Here are the top 10 Docker commands you should know:

docker run – Starts a new container.
docker build – Creates a new image from a Dockerfile.
docker push – Uploads an image to a repository.
docker pull – Downloads an image from a repository.
docker images – Displays a list of all available images.
docker ps – Displays a list of all running containers.
docker stop – Stops a running container.
docker rm – Removes a container.
docker rmi – Removes an image.
docker-compose – Allows defining and running multi-container applications.
