sudo apt update
sudo apt upgrade -y

安装必要工具

sudo apt install apt-transport-https

配置apt下载源

使用阿里源

aliyun_src=”https://mirrors.aliyun.com/docker-ce/linux/ubuntu/”

curl是自带的，没必要安装

curl -fsSL “${aliyun_src}gpg” | sudo gpg –dearmor -o /etc/apt/keyrings/docker.gpg
echo “deb [arch=$(dpkg –print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] ${aliyun_src} $(. /etc/os-release && echo “${VERSION_CODENAME}”) stable” | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

刷新源，这一步很重要

sudo apt update

通过apt安装docker

sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

添加镜像源

创建目录

sudo mkdir -p /etc/docker

写入配置文件

sudo tee /etc/docker/daemon.json <<-‘EOF’
{
“registry-mirrors”: [
“https://hub.crdz.gq”,
“https://hub.littlediary.cn”,
“https://docker.1panel.live”,
“https://hub.xdark.top”,
“https://docker.m.daocloud.io”,
“https://docker.kejilion.pro”,
“https://registry.dockermirror.com”,
“https://docker.unsee.tech”
]
}
EOF

配置不加sudo使用docker

sudo usermod -aG docker “${USER}”

重启docker服务

sudo systemctl daemon-reload && sudo systemctl restart docker
