Summarize common Docker commands

This article focuses on "summing up common Docker commands". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn "summing up Docker common commands"!

Scenario 1: download, run and delete COMMANDDESC view by image

Docker images lists all images (images) docker ps lists running containers (containers) docker ps-a lists all containers docker pull centos downloads centos images docker top 'container' view containers running programs inside the container

Docker exec-it container ID sh enters the container docker stop 'container' to stop a running container 'container' can be container ID or name docker start' container' start a stopped container docker restart 'container' restart container docker rm' container' delete container docker run-I-t-p: 80 LAMP / bin/bash run container and do http port forward docker exec-it 'container' / bin/bash into bashdocker exec-it / bin/sh of ubuntu container enter shdocker rm docker ps-a-Q of alpine container delete all The stopped container docker kill $(docker ps-a-Q) kills all running containers The function of $() is the same as ``image

Docker build-t wp-api. Build 1 image,-t (name and label of the image) wp-api (image name). (built directory) docker run-Imurt wp-api-t-I runs in interactive pseudo-terminal mode, you can view the output information docker run-d-p 80:80 wp-api image port-d background mode run image docker rmi [image-id] delete image docker rmi $(docker images-Q) delete all images docker rmi $(sudo docker images-- filter "dangling=true"-Q-no-trunc) delete useless image ocker run-- help help

Scenario 2: download the image and run docker run directly-- name ubuntu-it ubuntu bash docker cp dd ubuntu:tmp/ # copy the file dd to the container's / tmp directory Ctrl-p Ctrl-q # exit scenario 3: modify the image and save it to the private repository

Expected result: add apache to the ubuntu image and save the new image to the private repository

Docker exec-it ubuntu bash apt-get updateapt-get install apache2Ctrl-p Ctrl-q # exit docker commit-a "mir355"-m "ubuntu add apache2" {ID} private/ubuntu_apache:v1 # Save the image docker stop ubuntudocker rm ubuntudocker run-I-t-- name apache2-p 8080 private/ubuntu_apache:v1 / bin/bash/etc/init.d/apache2 startCtrl-p Ctrl-q # exit # rename the image via docker tag Make it match registry docker tag private/ubuntu_apache:v1 127.0.0.1:5000/private/ubuntu_apache:v1# save to private warehouse docker push 127.0.0.1:5000/private/ubuntu_apache:v1curl http://127.0.0.1:5000/v2/_catalog# download image docker pull 127.0.0.1:5000/private/ubuntu_apache:v1 here, I believe you have a better understanding of "summarizing common Docker commands" You might as well do it in practice.
