服务器部署docker

1.服务器部署docker

sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
printf "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable\n" | sudo dd of=/etc/apt/sources.list.d/docker.list bs=1 status=none
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

2.验证Docker安装

sudo docker run hello-world

运行这个命令，如果能看到 Hello from Docker! 的消息，就说明Docker已经成功安装并运行了
