ubuntu 安装 docker

ubuntu 22.04

1、更新升级apt

sudo apt update

sudo apt upgrade

2、安装必备的软件包以允许apt通过 HTTPS 使用存储库（repository）

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

3、添加Docker官方版本库的GPG密钥

先创建目录

sudo mkdir -p /etc/apt/keyrings

再添加密钥

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

4、设置存储库

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

5、安装docker

安装最新版本的Docker Engine、containerd 和 Docker Compose

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

6、验证docker是否安装成功

查看docker版本

docker version

7、查看docker运行状态

systemctl status docker

8、启动docker服务

sudo systemctl start docker

9、设置docker开机自动启动

sudo systemctl enable docker
