Ubuntu22安装Docker

Docker, Linux / 2023年12月7日 / hamster

docker官网下载地址https://docs.docker.com/engine/install/ubuntu/

其实根据官网安装步骤安装即可，但安装后发现docker下载速度极慢，所以需要修改其中几处，将下载地址改为国内镜像

sudo apt-get update

sudo apt-get install ca-certificates curl gnupg

sudo install -m 0755 -d /etc/apt/keyrings

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

###修改后
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

sudo chmod a+r /etc/apt/keyrings/docker.gpg


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

###修改后
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update

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

###若无意外，到这里便安装成功了

###测试
sudo docker run hello-world

#启动docker 
sudo service docker start

#停止docker 
sudo service docker stop

#重启docker 
sudo service docker restart

如何让非 root 用户管理 Docker

#创建docker群组
sudo groupadd docker

#将用户添加到docker组中
sudo usermod -aG docker $USER

#注销并重新登录
sudo reboot now
#或者如下命令来激活对组的更改
newgrp docker

#验证用户是否不再需要sudo
docker run hello-world

若是docker下载镜像速度慢，可以配置镜像加速器，链接地址https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors
