I hope it will be helpful for you to answer the doubts of "what are the common commands of Docker?" Next, please follow the editor to study!

1. What is Docker?

Docker is the world's leading software container platform. Docker is a kind of encapsulation of Linux container, which provides an easy-to-use interface to the container. It is currently the most popular Linux container solution. Generally speaking, the interface of Docker is quite simple, and users can easily create and use containers and put their own applications into containers. Containers can also be versioned, copied, shared, and modified, just like managing ordinary code.

After the rise of the concept of cloud services, the usage scenario and scope of Docker have further developed. now, with the increasing popularity of micro-service architecture, the perfect combination of micro-service and Docker makes it more convenient for operation and maintenance of micro-service architecture to deploy. So that's why so many friends now need to get started with Docker.

2. What are the advantages of using Docker?

The advantages of Docker boil down to four things: faster delivery and deployment; more efficient virtualization; easier migration and expansion; and easier management.

3. Share common commands:

Pull docker image

Docker pull image_name

View the image on the host. The Docker image is stored in the / var/lib/docker directory:

Docker images

Delete Mirror

Docker rmi docker.io/tomcat:7.0.77-jre7 or docker rmi b39c68b7af30

See which containers are currently running

Docker ps

View all containers

Docker ps-a

Start, stop, restart container commands:

Docker start container_name/container_id

Docker stop container_name/container_id

Docker restart container_name/container_id

After launching a container in the background, if you want to enter the container, you can use the attach command:

Docker attach container_name/container_id

Command to delete a container:

Docker rm container_name/container_id

View current system Docker information

Docker info

Download an image from Docker hub:

Docker pull centos:latest

Docker pull centos:latest
