Ubuntu 14.04 LXC Setup with Unprivileged Containers

http://blog.lifebloodnetworks.com/?p=2118 I have been spending a lot of time searching for alternatives to virtual machines. I do love my VMs but I hate the idea of dedicating resources (such as RAM) that never get used. There is memory ballooning but it is a trade off for the usage of other resources. Also I am crazy […]

Configuring Unprivileged LXC containers in Debian Jessie

Credited by https://myles.sh/configuring-lxc-unprivileged-containers-in-debian-jessie/ The gradual maturity of Linux Control Groups and in-kernel namespaces (i.e. net, user, mount, IPC, etc) has enabled powerful OS-level virtualisation utilities such as Docker and LXC to offer a lightweight, high-performing alternative to typical hardware based virtualisation (e.g. KVM). With OS-level virtualisation the host’s kernel handles all system calls generated from OS-level […]

Data Center Operating System

http://datacenteroperatingsystem.io/ About Hyperscale cloud orchestration platforms were once the purview for large companies with thousands of talented engineers (Google, Netflix, Facebook, Twitter). This led to a proliferation of non-standard bespoke tools built and developed for the same company. This is no longer the case any more. The merging of development and operations called “DevOps” are […]

Extra bridge interfaces get added automatically

http://unix.stackexchange.com/questions/70399/extra-bridge-interfaces-get-added-automatically https://insights.ubuntu.com/2015/11/10/converting-eth0-to-br0-and-getting-all-your-lxc-or-lxd-onto-your-lan/ https://wiki.debian.org/LXC/SimpleBridge For future readers, I wrote this email to some colleagues of mine who are working with me on configuring LXC and figuring out the bridging. Well, I spent most of the day today fussing with networking in LXC, and now things are a lot clearer, so I thought I’d pass on what […]

Skipping Docker for LXC for Local Development.

http://michaeldehaan.net/post/111599240017/skipping-docker-for-lxc-for-local-development Recently for $work things I had a chance to play around with raw LXC, which has been a great experience thus far. Ultimately Docker is getting a bit too much hype lately, and I think that hype properly belongs with much of the underlying technology, not the unionfs-esque glue. Given, popularizing Immutable Systems is […]
