Ubuntu18.0.4 安装 Docker

安装步骤：

1. 更新Ubuntu的apt源索引

sudo apt-get update

2. 安装包允许apt通过HTTPS使用仓库

sudo dpkg --configure -a

sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

3. 添加Docker官方GPG key

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null 

4. 更新apt源索引

sudo apt-get update

5. 安装

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

6. 启动

sudo systemctl enable docker
sudo systemctl start docker

7. 添加国内下载源，进入docker目录，没有的话创建一个

cd /etc/docker/

创建 daemon.json 文件，配置镜像加速器

{
	"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.ustc.edu.cn",
		"https://mirror.iscas.ac.cn",
		"https://docker.rainbond.cc"
	]
}

docker --version
