The top ten Docker commands that you will use frequently while working with Docker

Docker technology makes it possible to build, distribute, and run applications using containers. A Container is a piece of software that packages the code and all of its dependencies so that the application can execute regardless of the environment. The container encapsulates the program and its dependencies into a self-contained package that can operate anywhere. The absence of physical hardware allows for more efficient use of computing resources. Containers provide virtualization at the operating system level. Furthermore, developers may communicate more quickly without having to worry about which software dependencies they need to install. A container is a runnable image instance. An image is a read-only template containing Docker container creation instructions. The Docker API or CLI can be used to create, start, stop, move, or destroy containers. A single container can be connected to one or more networks, and storage can be attached to it. A new picture can also be produced based on the container's current state. Containers can be shared, guaranteeing that everyone who communicates with it receives the same container and operates in the same manner. The difference between 'docker kill' and 'docker stop' is that 'docker stop' allows the container time to shut down gracefully, whereas 'docker kill' kills the container if it is taking too long to halt.

1. Docker –version

This command is used to get the currently installed version of the docker

2. Docker pull

Usage: docker pull

This command is used to pull images from the docker repository

3. Docker run – This command is used to create a container from an image

Usage: docker run -it -d

4. Docker ps – This command is used to list the running containers
5. Docker ps -a

This command is used to show all the running and exited containers

6. Docker exec

Usage: docker exec -it bash

This command is used to access the running container

7. Docker stop

Usage: docker stop

This command stops a running container

8. Docker kill

Usage: docker kill

This command kills the container by stopping its execution immediately.

9. Docker commit

Usage: docker commit

This command creates a new image of an edited container on the local system.

10. Docker push

Usage: docker push

This command is used to push an image to the docker hub repository

These were the top ten Docker commands that you will use frequently while working with Docker. The Docker container trend is unstoppable, with firms actively seeking people with Docker certification, and a solid understanding of these Docker commands will provide you with the required competence.
