Docker is a powerful tool for containerization that enables developers to package applications along with their dependencies into a standardized unit called a container. Whether you're just starting with Docker or need a quick reference, this cheat sheet covers essential Docker commands and concepts to help you navigate through your containerization journey.

Here's a detailed Docker cheat sheet for your reference:

docker --version - Show Docker version.

docker run [OPTIONS] IMAGE [COMMAND]- Run a command in a new container.

docker ps -List running containers.

docker ps -a - List all containers, including stopped ones.

docker images - List all Docker images.

docker pull IMAGE - Pull an image from a registry.

docker build -t NAME:TAG - Build an image from a Dockerfile.

docker push NAME:TAG - Push an image to a registry.

docker exec -it CONTAINER COMMAND - Execute a command in a running container.

docker stop CONTAINER - Stop a running container.

docker start CONTAINER - Start a stopped container.

docker restart CONTAINER - Restart a running container.
