After working for many years, I’ve encountered numerous users, and some content is not applicable

Installation can refer to the manual from Tsinghua University: https://mirrors.tuna.tsinghua.edu.cn/help/docker-ce/

Install

Due to an unknown mysterious force, it is recommended to use cloud vendor-provided repository addresses for Docker installations within China; here, we recommend 阿里云

Set repository source address

yum install yum-utils device-mapper-persistent-data lvm2 && \
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

Deploy the latest version

Docker, as a commonly used background service, is recommended to be set up for startup on boot. This command applies to CentOS 7.

sudo yum install -y docker-ce docker-ce-cli containerd.io && systemctl enable --now docker

Deploy specified version

Please provide the Chinese text you want me to translate. I am ready when you are.

yum list docker-ce --showduplicates | sort -r
sudo yum install -y docker-ce-18.09.2-3.el7 docker-ce-cli-18.09.2-3.el7 containerd.io-18.09.2-3.el7 && systemctl enable --now docker

Add Docker permissions for regular users

sudo usermod -aG docker ${USER}

Uninstall

sudo yum erase -y docker-ce docker-ce-cli containerd.io

Everyday use

Mirror Acceleration

There are still unknown mysterious forces causing slow image pulls. Domestic cloud providers have stepped up, offering many acceleration services; I still recommend them.

To obtain the accelerated access addresses, please register for an Alibaba Cloud account. This service is free, and Alibaba Cloud also provides a free image building service.

Highly recommended control panel

docker volume create portainer_data && \
docker run -d --name=portainer --restart=always -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:2.20.3-alpine

Common Command Combinations

https://docs.docker.com/engine/reference/commandline/docker/

Check container runtime status, add the __INLINE_CODE_0 parameter, view detailed container information; ignore image information at this time

docker ps --format "{{.Names}}: {{.Ports}}: {{.Size}}"
#portainer: 0.0.0.0:8000->8000/tcp, 0.0.0.0:9000->9000/tcp: 0B (virtual 172MB)
#influxdb: 0.0.0.0:8086->8086/tcp: 183B (virtual 311MB)

Stop all containers

docker stop $(docker ps -a -q)

Delete all images

dokcer rmi $(docker images -a -q)

Export image

docker save <IMAGE NAME>:<IMAGE TAG> > -o XXX.tar

Export image and compress

docker save <IMAGE NAME>:<IMAGE TAG> | gzip > XXX.tar

Import image

docker load -i XXX.tar
