安装方法一（脚本安装）

脚本安装是最推荐的方式，只需要输入下面的命令，等待自动安装好即可。

sudo curl -sSL https://get.docker.com | sh

如果采用这一步安装成功，可直接跳到下文的图形界面安装那里继续阅读。

pi@raspberrypi:~ $ sudo curl -sSL https://get.docker.com | sh

    If you would like to use Docker as a non-root user, you should now consider
    adding your user to the "docker" group with something like:
    
      sudo usermod -aG docker pi
    
    Remember that you will have to log out and back in for this to take effect!
    
    WARNING: Adding a user to the "docker" group will grant the ability to run
             containers which can be used to obtain root privileges on the
             docker host.
             Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
             for more information.

安装方法二（apt 安装）

由于 Raspbian 基于 Debian，我们还可以使用 apt 来安装 Docker，首先需要更新一下软件包的索引。

sudo apt-get update

安装 HTTPS 所依赖的包

sudo apt-get install apt-transport-https \
                         ca-certificates \
                         software-properties-common

添加 Docker 的 GPG key

curl -fsSL https://yum.dockerproject.org/gpg | sudo apt-key add -

验证 key id:

apt-key fingerprint 58118E89F3A912897C070ADBF76221572C52609D

设置稳定的 repository:

sudo add-apt-repository \
     "deb https://apt.dockerproject.org/repo/ \
      raspbian-$(lsb_release -cs) \
      main"

注意：如果 add-apt-repository 命令遇到问题，可以尝试将下面这行添加到树莓派软件源 sources.list，操作如下：

sudo nano /etc/apt/sources.list

添加一行：

deb https://apt.dockerproject.org/repo/ raspbian-RELEASE main

根据自己系统版本调整上面的 RELEASE。通过下面的命令可以查看发行版。

lsb_release -cs

安装 Docker

sudo apt-get update
sudo apt-get -y install docker-engine

常用配置和工具命令

#查看 Docker 版本 docker -v sudo docker pull 仓库/镜像:版本（留空的话默认为 latest） sudo docker run 加参数，用来创建容器
#查看运行容器 sudo docker ps
#查看所有下载的镜像 sudo docker images
#进入容器终端 sudo docker exec -i -t ha /bin/bash
#实时查看10行的 ha 日志 sudo docker logs -f -t --tail 10 ha
#重启 systemctl 守护进程 sudo systemctl daemon-reload
#设置 Docker 开机启动 sudo systemctl enable docker
#开启 Docker 服务 sudo systemctl start docker  
#下载 Docker 图形化界面 portainer sudo docker pull portainer/portainer
#创建 portainer 容器 sudo docker volume create portainer_data
#运行 portainer sudo docker run -d -p 9000:9000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer
