树莓派安装 docker

系统选择

我使用的是2018-04-18的RASPBIAN STRETCH LITE版本，我之前用过时间靠前的版本但是安装总是失败，还了这个版本是成功的。官网上说:

To install Docker CE, you need the 64-bit version of one of these Debian or Raspbian versions:

Buster 10 (Docker CE 17.11 Edge only)

Stretch 9 (stable) / Raspbian Stretch

Jessie 8 (LTS) / Raspbian Jessie

Wheezy 7.7 (LTS)

Docker CE is supported on both x86_64 (or amd64) and armhf architectures for Jessie and Stretch.

但是我看了树莓派目前的官方版本是32位的。

1file /bin/dash
2/bin/dash: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=18bddc2d67c785bbaaf97cbb2c0dd5420a1861b3, stripped

但是，也安装成功了。

修改树莓派源

我认为这是非常重要的一步，我在用官方源的时候opencas的镜像总是无法访问，后来换成了

1# /etc/apt/sources.list
2deb http://mirrors.shu.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi

之后，奇迹的可以用了。

安装docker

根据官方文档的说法：一些方式是不适用于rasbian系统的。

Raspbian users cannot use this method!
For Raspbian, installing using the repository is not yet supported. You must instead use the convenience script.

官方推荐是使用一个便捷脚本，我在没有改源之前使用这个脚本也没有成功，换了源就安装成功了。

32If you would like to use Docker as a non-root user, you should now consider
33adding your user to the "docker" group with something like:
34
35  sudo usermod -aG docker your-user
36
37Remember that you will have to log out and back in for this to take effect!
38
39WARNING: Adding a user to the "docker" group will grant the ability to run
40         containers which can be used to obtain root privileges on the
41         docker host.
42         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
43         for more information.
44pi@raspberrypi:~ $ sudo usermod -aG docker `whoami`

重启下cmd界面（否则还是需要sudo），安装成功。
