docker - 如何为Docker配置Polipo的HTTP代理以部署Kubernetes

Question

我是Docker的初学者。想知道这样做是否是一种好习惯，什么是最好的方法呢？

系统:Ubuntu LTS 16.04.2

我想在具有代理的服务器上部署Kubernetes。由于某些问题，我使用polipo将sock5代理转换为http代理。 http代理已成功应用于终端。然后我搜索了:
https://docs.docker.com/engine/admin/systemd/#http-proxy
并且我在 /etc/systemd/system/docker.service.d/http-proxy.conf 中添加了HTTP_PROXY环境变量:

[Service]

Environment="HTTP_PROXY=http://127.0.0.1:8123/"

然后执行以下操作:

$ sudo systemctl show --property Environment docker Environment=HTTP_PROXY=http://127.0.0.1:8123/

$ sudo systemctl daemon-reload

$ sudo systemctl restart docker

然后我成功安装了 kubelet kubeadm kubectl kubernetes-cni 并运行了以下命令:

# kubeadm init

这是操作的结果:

root@ubuntu16:~# kubeadm init

然后它不继续，我跑了

现在我很困惑如何解决这个问题。我正在网上搜索很长时间。但是没用。请帮助或尝试给出一些想法来实现这一目标。

提前致谢。

安装它，我进行了修改以在docker＆kubelet之间对齐cfgroups:

docker 信息| grep -i cgroup

在文件 /etc/systemd/system/kubelet.service.d/10-kubeadm.conf中
修改相应的行以具有:

Environment =“KUBELET_CGROUP_ARGS =-cgroup-driver = cgroupfs”

再见
