Docker 1.13 Proxy

[Sand Glass]

I use CentOS7,docker 1.13.

[lb@localhost pyuv_docker]$ uname -a
Linux localhost.localdomain 3.10.0-693.11.6.el7.x86_64 #1 SMP Thu Jan 4 01:06:37 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
[lb@localhost pyuv_docker]$ docker -v
Docker version 1.13.1, build 28e44a9

I have a shadowsocks client, config (host:port)127.0.0.1:1081 as a proxy.

In my dockerfile I try to set as fllow:

ENV http_proxy 127.0.0.1:1081
ENV https_proxy 127.0.0.1:1081

When I build an image using the proxy, failed. Show the following error:

One of the configured repositories failed (Unknown),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
 1. Contact the upstream for the repository and get them to fix the problem.
 2. Reconfigure the baseurl/etc. for the repository, to point to a working
    upstream. This is most often useful if you are using a newer
    distribution release than is supported by the repository (and the
    packages for the previous distribution release still work).
 3. Run the command with the repository temporarily disabled
        yum --disablerepo=<repoid> ...
 4. Disable the repository permanently, so yum won't use it by default. Yum
    will then just ignore the repository until you permanently enable it
    again or use --enablerepo for temporary usage:
        yum-config-manager --disable <repoid>
    or
        subscription-manager repos --disable=<repoid>
 5. Configure the failing repository to be skipped, if it is unavailable.
    Note that yum will try to contact the repo. when it runs most commands,
    so will have to try and fail each time (and thus. yum will be be much
    slower). If it is a very temporary problem though, this is often a nice
    compromise:
        yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: base/7/x86_64
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was
14: curl#7 - "Failed connect to 127.0.0.1:1081; Connection refused"

The question is, How can I config the proxy using older version docker?
