How is “lxd” different from lxc/docker?

Questions How does lxd provide Full operating system functionality within containers, not just single processes? How is it different from lxc/docker + wrappers? Is it similar to a container that is launched with docker + supervisor/wrapper script to contain multiple processes in one container? In other words: What can I do with lxd that I cannot do with some wrappers over lxc and docker ? Why is it available only in ubuntu if they are making use of mainline kernel features (namespaces and cgroup )?

测试环境用LXD替换掉了KVM

生命不息,折腾不止。在折腾中成长,在踩坑中进步。 前言 不错,再一次折腾了一把,这次是把测试环境的hadoop集群从KVM中迁移到了LXD容器中。目前运行很稳定,这次就来分享一下这次的体会和一些感受吧。 由于这篇blog并不是纯技术文章详细介绍LXD搭建和维护的,只是谈谈使用的一些感受体会,所以不会有详细的安装和使用的过程了,感兴趣的读者可以找官方文档去实践。不过这玩意目前来看文档确实比较少,好在使用特别简单。 LXD vs KVM 关于KVM可能很多人都不陌生,谈到Linux下的虚拟机,津津乐道的就属KVM和XEN了。这里我不打算对KVM进行拓展了,关于市面上KVM的资料已经烂大街了。测试环境少不了虚拟机,通过虚拟化隔离资源的特性,可以充分利用物理机的资源,扩充机器数量。不过当初研究KVM的时候,着实痛苦了一把。配置相对繁琐,为了性能还需要启用部分硬件的半虚拟化支持,当时记得还买过一本《深度实践KVM》研读来着。 现在具体谈谈LXD吧。不得不说,宣传也是很重要的一项工作,Ubuntu对这玩意的宣传可以说不遗余力,很多地方都能看到LXD的消息。我个人比较喜欢Ubuntu的一些技术,平时也关注一些Ubuntu社区的动向。在我看来,ubuntu的更新节奏较快,总是能尽快的吸纳新的技术用于生产,跟着Ubuntu的节奏总是能尽快的接触到新奇有趣的东西

首先先看看效果,几个容器全开,也占不了多少内存。 折腾了快一天了,总算搞起来了。 lxc list +---------------+---------+---------------------+----------------------------------------------+------------+-----------+ | NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS | +---------------+---------+---------------------+----------------------------------------------+------------+-----------+ | centos6 | RUNNING | 10.54.46.127 (eth0) | fd42:20c0:8696:546:216:3eff:feb8:af5c (eth0) | PERSISTENT | 0 | +---------------+---------+---------------------+----------------------------------------------+------------+-----------+ | centos7 | RUNNING | 10

migrating lxc to lxd

问题 I've looked all over, but can't see if there is a way. I have a couple LXC containers running Ubuntu 14.04 on top of a Ubuntu 14.04 Host. They've become pretty important to me, so I want to be able to easily backup / migrate the LXC containers to another server if the host's hardware should fail. I've built a new Ubuntu 15.1 server now with LXD and have logged out and back in and see the new group. For testing, I tar'd one of my existing LXC containers up with the --numeric-owner switch on my
