Docker 是一个开源的容器引擎，可以让开发者打包他们的应用以及依赖包到一个可移植的容器中，然后发布到任何流行的 Linux 机器上，也可以实现虚拟化。本文将详细介绍如何在 Debian 12 系统上安装 Docker。

安装

安装 Docker 需要以下条件：

• 已经安装的 Debian 12 系统 (VM 或硬件服务器)
• root 权限

可以使用以下命令安装 Docker：

sudo su &&
apt update &&
apt install ca-certificates curl gnupg apt-transport-https gpg

下载 GPG 密钥并将其存储在系统中：

curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /usr/share/keyrings/docker.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker.gpg] https://download.docker.com/linux/debian bookworm stable" |tee /etc/apt/sources.list.d/docker.list > /dev/null 
apt update

安装 Docker 包：

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

验证

可以使用以下命令检查 Docker 是否安装成功并是否在系统启动时自动启动：

systemctl is-active docker

测试

也可以通过启动 hello-world Docker镜像来测试安装是否成功：

docker run hello-world

如果一切正常，将看到类似以下输出：

Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
478afc919002: Pull complete
Digest: sha256:03b30c6a3c320ff172b52bd68eddffde6ded08ce47e650fe52de861c5e9df46d
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.
    (arm64v8)
 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
