Docker [Raspberry Pi OS](https://www.raspberrypi.org/software/operating-systems/) 操作系统:
* Raspberry Pi OS Buster
** `Raspberry Pi OS` [](https://www.raspberrypi.org/) 官方支持,并推荐用作树莓派的首选系统,其基于 `Debian`。

```bash
# $ curl -fsSL test.docker.com -o get-docker.sh
$ curl -fsSL get.docker.com -o get-docker.sh
$ sudo sh get-docker.sh --mirror Aliyun
# $ sudo sh get-docker.sh --mirror AzureChinaCloud
```
Docker (stable)
## Docker
```bash
$ sudo systemctl enable docker
$ sudo systemctl start docker
```
## docker
`docker` 使 [Unix socket](https://en.wikipedia.org/wiki/Unix_domain_socket) 与 Docker 引擎通讯。而只有 `root` 用户和 `docker` 组的用户才可以访问 Docker 引擎的 Unix socket。出于安全考虑一般 Linux 系统上不会直接使用 `root` 用户。因此,更好地做法是将需要使用 `docker` 的用户加入 `docker` 用户组。
`docker`
```bash
$ sudo groupadd docker
```
`docker`
```bash
$ sudo usermod -aG docker $USER
```

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.
(arm32v7)
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
