安装docker

因为deepin的特殊

安装方式详见：

大概就是网络的问题
添加docker官方仓库这一步骤报错了：

这一点先不论：
用

中的办法，运行hello world试试

docker run --name hello hello-world

发现权限不够：
用了sudo
上个链接中的办法根本没办法使用sudo gpasswd -a ${USER} docker
提示我根本不存在docker用户

hf@hf-PC:~$ sudo gpasswd -a ${hf} docker
gpasswd：用户“docker”不存在

之后用了：

之中的办法

让普通用户也能使用
但是之前已经有了进程

解决

试了用docker run hello-world直接运行，得到与之前相同的结果：

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/

总算是调试好了？
累死了。

PS：

话说我的docker版本：
用sudo apt-get install docker-ce得到的：

docker-ce 已经是最新版 (18.06.0_ce3-0~ubuntu)。
