4.2 Install the Docker packages.(选择安装包)

:::: code-group
::: code-group-item 安装最新版

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

:::
::: code-group-item 指定版本

# To install a specific version of Docker Engine, start by listing the available versions in the repository: # List the available versions: apt-cache madison docker-ce | awk '{ print $3 }'  5:24.0.0-1~ubuntu.22.04~jammy 5:23.0.6-1~ubuntu.22.04~jammy # Select the desired version and install: VERSION_STRING=5:24.0.0-1~ubuntu.22.04~jammy sudo apt-get install docker-ce=$VERSION_STRING docker-ce-cli=$VERSION_STRING containerd.io docker-buildx-plugin docker-compose-plugin ...

4.3 Verify that the Docker Engine installation is successful by running the hello-world image.(验证是否安装成功)

:::: code-group
::: code-group-item 输入

sudo docker run hello-world 

:::
::: code-group-item 输出

Unable to find image 'hello-world:latest' locally  latest: Pulling from library/hello-world  719385e32844: Pull complete   Digest: sha256:4f53e2564790c8e7856ec08e384732aa38dc43c52f02952483e3f003afbf23db  Status: Downloaded newer image for hello-world:latest    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.    To try something more ambitious, you can run an Ubuntu container with:   $ docker run -it ubuntu bash    Share images, automate workflows, and more with a free Docker ID:   https://hub.docker.com/   For more examples and ideas, visit:   https://docs.docker.com/get-started/
