Ubuntu系统安装docker

使用一键安装脚本快速部署Docker#

将以下命令复制到一个新建的文本文件，命名为 install-docker.sh

#! /bin/bash

date "+%Y年%m月%d日 周%w %H:%M:%S"
echo '开始安装 Docker'
apt-get update
echo y | apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
apt-get update
echo y | apt-get install docker-ce docker-ce-cli containerd.io
docker run hello-world
echo 'Docker 安装完成，请检查是否出现 Hello from Docker!'

随后将文件复制到Ubuntu系统内你想要上传的路径，这里使用scp传输，方便快捷。

在install.sh存在目录打开终端，输入以下内容，其中

scp install.sh root@IP:[需要保存该文件的绝对路径]

上传完成后使用终端连接到Ubuntu ，在你上传的目录里输入以下命令

sh install.sh

等待脚本运行完成，当出现Hello from Docker字样，即表示安装成功，此时输入：

docker info

若出现以下内容，docker已经安装完成
