1.更新系統軟件包

#確保您的系統軟件包是最新的。這有助于避免安裝過程中可能遇到的問題
sudo apt update
sudo apt upgrade -y

2.安裝必要的依賴

sudo apt install apt-transport-https ca-certificates curl software-properties-common -y

3.替換軟件源

原來/etc/apt/sources.list中的軟件源

更換/etc/apt/sources.list中的軟件源

echo "deb http://mirrors.aliyun.com/ubuntu/ $(lsb_release -s -c) main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ $(lsb_release -s -c) main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ $(lsb_release -s -c) main restricted universe multiverse
" | sudo tee /etc/apt/sources.list

替換后

#更新軟件包列表
sudo apt-get update

4.確保Docker依賴包安裝成功

sudo apt-get install ca-certificates curl gnupg lsb-release

5.添加Docker的官方GPG密鑰

#為了確保下載的軟件包的安全性
curl -fsSL https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

6.添加Docker的APT源

echo "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

7.更新APT包索引

sudo apt-get update

8.安裝Docker引擎

sudo apt-get install docker-ce docker-ce-cli containerd.io

9.啟動Docker并設置開機自啟

sudo systemctl start docker
sudo systemctl enable docker

10.修改鏡像地址

vim /etc/docker/daemon.json

{

"registry-mirrors" : ["https://docker.registry.cyou",

"https://docker-cf.registry.cyou",

"https://dockercf.jsdelivr.fyi",

"https://docker.jsdelivr.fyi",

"https://dockertest.jsdelivr.fyi",

"https://mirror.aliyuncs.com",

"https://dockerproxy.com",

"https://mirror.baidubce.com",

"https://docker.m.daocloud.io",

"https://docker.nju.edu.cn",

"https://docker.mirrors.sjtug.sjtu.edu.cn",

"https://docker.mirrors.ustc.edu.cn",

"https://mirror.iscas.ac.cn",

"https://docker.rainbond.cc",

"https://do.nark.eu.org",

"https://dc.j8.work",

"https://dockerproxy.com",

"https://gst6rzl9.mirror.aliyuncs.com",

"https://registry.docker-cn.com",

"http://hub-mirror.c.163.com",

"http://mirrors.ustc.edu.cn/",

"https://mirrors.tuna.tsinghua.edu.cn/",

"http://mirrors.sohu.com/"

],

"insecure-registries" : [

"registry.docker-cn.com",

"docker.mirrors.ustc.edu.cn"

],

"debug": true,

"experimental": false

}

systemctl daemon-reload
systemctl restart docker

?11.驗證Docker安裝

sudo docker run hello-world

回顯如下，則表示Docker安裝成功：

Hello from Docker!

This message shows that your installation appears to be working correctly.

12.（可選）非root用戶運行Docker

默認情況下，Docker命令需要以root用戶或sudo權限運行。為了允許非root用戶運行Docker命令，可以將用戶添加到?docker組

sudo usermod -aG docker $USER

然后注銷并重新登錄，或者運行以下命令使組更改立即生效

newgrp docker

13.Docker Compose的安裝

#Docker Compose是一個用于定義和運行多容器Docker應用程序的工具
sudo apt update
# 安裝docker-compose
sudo apt install docker-compose
# 驗證是否安裝成功
sudo docker-compose --version
