ubuntu安装docker环境

一、卸载旧版本

sudo apt-get remove docker docker-engine docker.io containerd runc

二、使用存储库安装

1、安装依赖工具

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

2、添加docker官方GPG key

sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

3、配置软件包源

 echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

4、安装Docker Engine

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

三、配置阿里云容器镜像

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors":["https://xxxxxxxx.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

    使用您的阿里云容器镜像加速器地址替换

四、非root用户身份管理Docker

1、创建用户组

 sudo groupadd docker

2、添加当前用户到docker用户组

sudo usermod -aG docker $USER

3、注销登录或者重启使更改生效；或执行下面的命令在当前会话立即生效

newgrp docker
