docker 设置代理，解决全局代理不生效的问题

linux的全局代理设置，HTTP_PROXY、HTTPS_PROXY对docker无效，需要单独给docker配置代理，查找到资料大多数是基于docker service版本的配置，而我是直接用二进包安装的，不太适用

而且很多搜到配置已经过时了，而且也没有给出docker的版本

以下是经过验证的的可行的配置，基于docker 27.3.1 版本 

1. 如下文件，添加"proxies"配置，分别配置上代理信息，关注https-proxy配置，docker是使用https的，其它两个是可以不配置的，只是示例

liufy@liufy-d5:~/dev$ cat /etc/docker/daemon.json
{
  "data-root":"/data/docker"
  ,"proxies": {
    "http-proxy": "http://192.168.0.10:10809",
    "https-proxy": "http://192.168.0.10:10809",
    "no-proxy": "*.test.example.com,.example.org,127.0.0.0/8"
   }
}

2.重启dockerd,并验证是否生效。正常会看到我们配置的代理信息

liufy@liufy-d5:~/dev$ docker info|grep -Ei proxy
 HTTP Proxy: http://192.168.0.10:10809
 HTTPS Proxy: http://192.168.0.10:10809
 No Proxy: *.test.example.com,.example.org,127.0.0.0/8

3.用hello-world 验证一下

liufy@liufy-d5:~/dev$ docker run hello-world
Unable to find image 'hello-world:latest' locally

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
