The following are the commands being covered:

docker -version docker pull docker run docker ps docker

• ps -a

docker exec docker stop docker kill docker

• commit

docker

• login
• docker push
• Images

of Docker Docker RM Docker

• RMI
• Building

Docker So, let’s get started:Docker commands 1. docker -version This command is used to get the currently installed version of Docker

Usage: docker run -it -d

<image name>

This command is used to create a container from an image

This command is used to enumerate

running containers 5 commands. Docker PS-A

This command is used to display all

running and exited containers <img src=”https://d1jnx9ba8s6j9r.cloudfront.net/blog/wp-content/uploads/2017/11/docker_ps-Docker-Commands-Edureka-e1510653881541.png” alt=”docker_ps – Docker – Edureka” />6 commands.

docker exec

Usage: docker exec -it <container id> bash

This command is used to access the running container

Usage: docker stop

<container id>

This command stops a running container

Usage: docker kill <container id>

This command kills the container by stopping its execution immediately. The difference between ‘docker kill’ and ‘docker stop’ is that ‘docker stop’ gives the container time to shut down properly, in situations where it takes too long to stop the container, you can choose to kill it

9. Docker Confirmation

Usage: docker commit <conatainer id> <username/imagename>

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