Summary of common commands in docker

Docker search centos:7.2.1511 # with a specified version number

Docker search centos # default latest without version number

Docker pull warehouse server: Port / project name / image name: tag (version) number

View local image: docker images

Name of the repository to which the REPOSITORY # image belongs

TAG # image version number (identifier), default is latest

IMAGE ID # Image unique ID tag

CREATED # Image creation time

Size of the VIRTUAL SIZE # image

Command summary:

Docker load-I centos-latest.tar.xz # Import local image docker save centos > / opt/centos.tar # centos # Export image docker rmi image ID/ image name # delete the image of the specified ID, when starting the container through the image

The waiting mirror cannot be deleted unless all the containers are closed

Docker rm Container ID/ Container name # Delete Container docker rm Container ID/ Container name-f # Force deletion of a running container

Delete Container Operation

Docker stop $(docker ps-a-Q) # closes all running containers normally

Docker kill $(docker ps-a-Q) # forcibly closes all running containers

Docker rm-f docker ps-aq-f status=exited batch delete exited containers

Docker rm-f $(docker ps-a-Q) batch delete all containers

Will go directly to the container and randomly generate the container ID and name

[root@docker-server1 ~] # docker run-it docker.io/centos bash

[root@11445b3a84d3 /] #

# exit the container without logging out of ctrl+p+q

Docker ps-a # shows all containers

Specify port mapping:

Method 1: local port 81 is mapped to container port 80:

Docker run-p 81:80-name nginx-test-port1 nginx

Method 2: local IP: local port: container port

Docker run-p 192.168.10.205 docker run 82bureau 80-- name nginx-test-port2 docker.io/nginx

Method 3: local IP: local random port: container port

Docker run-p 192.168.10.205-name nginx-test-port3 docker.io/nginx

Method 4: native ip: local port: container port / protocol. Default is tcp protocol.

Docker run-p 192.168.10.205:83:80/udp-- name nginx-test-port4

Docker.io/nginx

Method 5: map multiple ports + protocols at one time:

Docker run-p 86:80/tcp-p 443:443/tcp-p 53:53/udp-- name nginx-test-port5

Docker.io/nginx

# View the Nginx container access log:

[root@docker-server1 ~] # docker logs nginx-test-port3 # View at once

[root@docker-server1 ~] # docker logs-f nginx-test-port3 # continuously view

Docker port nginx-test-port5

Docker run-it-- name nginx-test nginx

Docker run-d-P-- name nginx-test1 docker.io/nginx # background launch container

Create and enter the container:

[root@docker-server1] # docker run-t-I-name test-centos2 docker.io/centos / bin/bash

[root@a8fb69e71c73 /] # # enter the container directly after creating the container

Docker run-d-name centos-test1 docker.io/centos running in the background

Docker run-it-rm-name nginx-delete-test docker.io/nginx

Use the attach command:

# the docker attach container name is used. Attach is similar to vnc, and the operation will be performed in each container interface.

Shows that all operations that enter the container in this way are displayed synchronously and the container will be closed after exit

Closed, and the container is closed after exiting with exit. It is not recommended. You need to enter the capacity with shell environment.

Devices, such as centos, for example:

[root@s1 ~] # docker run-it centos bash

[root@63fbc2d5a3ec /] #

[root@s1 ~] # docker attach 63fbc2d5a3ec

[root@63fbc2d5a3ec /] #

Enter the running container

Docker exec-it 8b32ccf52307 bash
