在Docker容器wget失败,似乎http代理不起作用在Centos 7.3

我遇到了一个问题:Docker容器中的wget失败(CentOS 7.3)。 我在网络上搜索了相关的解决方案,试了一下,但是“wget”还是不行。

如何调试该问题? 任何人都可以帮助我? 谢谢

详细步骤如下:

  1. 在CentOS 7.3上安装docker-ce 17.06.0
  2. /etc/systemd/system/docker.service.d/http-proxy.conf设置http_proxy
  3. 刷新changese: sudo systemctl daemon-reload
  4. 重启Docker: sudo systemctl restart docker
  5. 运行一个容器
  6. 在容器中,ping http代理成功,但在Docker容器中发生“wget”失败。
  7. 尝试在/etc/default/docker/etc/sysconfig/docker docker中设置代理,甚至用http代理启动dockerd。 但仍然失败

在host ==>中运行“wget”(通过代理135.245.48.34:8000)
