ubuntu 安装docker环境

Ubuntu安装Docker环境的步骤如下：

1. 更新系统和添加Docker GPG密钥：

sudo apt update && sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

2. 添加Docker的apt repository到系统：

echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

3. 更新软件包列表并安装Docker：

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

4. 启动和启用Docker服务：

sudo systemctl start docker
sudo systemctl enable docker

5. 验证Docker是否安装成功：

sudo docker run hello-world
