1. 安装所需要环境

    sudo apt update
sudo apt install  ca-certificates  curl gnupg  lsb-release lsb-core apt-transport-https

  2. 添加 Docker 的官方 GPG 密钥

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

  3. 使用以下命令设置存储库

    echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
# 修改公钥权限
sudo chmod a+r /etc/apt/keyrings/docker.gpg

  4. 安装 Docker 引擎

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

  5. WSL需要使用以下命令启动docker

    sudo service start docker

  6. 通过运行映像来验证 Docker 引擎是否已正确安装。hello-world

    sudo docker run hello-world

  7. 出现类似于以下信息即为成功

    Unable to find image 'hello-world:latest' locally

Hello from Docker!
This message shows that your installation appears to be 		working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
 3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
