I am trying to build a reverse-proxy to talk to certain APIs(like Twitter, Github, Instagram) that I can then call with my reverse-proxy to any (client) applications I want (think of it like an API-manager). Also, I am using an LXC-container to do this. For example, here is the simplest of code that I hacked from the examples on the Twisted Docs: from twisted.internet import reactor from twisted.web import proxy, server from twisted.python.log import startLogging from sys import stdout startLogging(stdout) site = server.Site(proxy.ReverseProxyResource('https://api.github.com/users/defunkt',

LXC(LinuX Container)之namespaec和cgroup namespace概述 从操作系统级上实现了资源的隔离，它本质上是宿主机上的进程（容器进程），所以资源隔离主要就是指进程资源的隔离。实现资源隔离的核心技术就是 Linux namespace。这技术和很多语言的命名空间的设计思想是一致的（如 C++ 的 namespace）。 Linux的命名空间机制提供了一种资源隔离的解决方案。PID,IPC,Network等系统资源不再是全局性的，而是属于特定的Namespace。Linux Namespace机制为实现基于容器的虚拟化技术提供了很好的基础，LXC（Linux containers）就是利用这一特性实现了资源的隔离。不同Container内的进程属于不同的Namespace，彼此透明，互不干扰。 Linux内核支持的namespace类型 Linux内核里面实现了7种不同类型的namespace。 名称 宏定义 隔离内容 Cgroup CLONE_NEWCGROUP Cgroup root directory (since Linux 4.6) IPC CLONE_NEWIPC System V IPC, POSIX message queues (since Linux 2.6.19) Network CLONE_NEWNET Network

I have the lxc, it has a running application. To edit the code of this application on own computer(Ubuntu 13.10), I want to mount a directory lxc. How can this be done? for example /var/lib/lxc/ubuntu_12_04/rootfs/home/ mounted in /mnt/lxc Use "mount --bind" man 8 mount -B, --bind Remount a subtree somewhere else (so that its contents are available in both places). Example # make a mount point sudo mkdir /mnt/lxc # mount existing directory on the mount point mount --bind /var/lib/lxc/ubuntu_12_04/rootfs/home/ /mnt/lxc Notes Root has access to /var/lib/lxc/ubuntu_12_04/rootfs/home/ even without

I am trying to create deb package from LXC rootfs, and after creating it I want to install that package any computer. Up to this point I achieved packaging and installing deb package, however after installation of LXC package, I cannot be superuser in that lxc. I get this error when I use "sudo" command. sudo: effective uid is not 0, is sudo installed setuid root? thanks in advance. I just had this same exact problem on Mac OS after strangely deciding to screw my own system by doing: sudo chmod -R /usr/bin . If that's someone else's case just open Disk Utility , select your OS disk ("Macintosh
