“Join us as we discuss Docker and linux containers…”
“I spoke to Stéphane about my ideas at the time and he introduced me to python3-lxc that he introduced on his blog yesterday. It provides Python bindings for liblxc, so I took the advantage of that and mostly re-implemented RLXC in Python and called it LLXC. The name doesn’t particularly mean anything, I’m open to suggestions for what to call it, if anyone cares.
Here are some screenshots that explains some of it better than I could do in words:…”
“One of our top goals for LXC upstream work during the Ubuntu 12.10 development cycle was reworking the LXC library and turn it from a private library mostly used by the other lxc-* commands into something that’s easy for developers to work with and is accessible from other languages with some bindings.
Although the current implementation isn’t complete enough to consider the API stable and some changes will still happen to it over the months to come, we have pushed the initial implementation to the LXC staging branch on github and put it into the lxc package of Ubuntu 12.10…”
“EC2 is already a (para)virtualized environment, which means it’s nearly impossible to run your own virtualization (KVM/VirtualBox/qemu) from inside that environment. However, Linux recently introduced a new system into the kernel, called
cgroups, which provides a way to isolate process groups from each other in the kernel. A project was soon formed around this new technology, which allows for very thin, fast, and secure quasi-virtualization. It’s called LXC, short for LinuX Containers. And it works in EC2 perfectly…”
“Quite a few people have been asking for a status update of LXC in Ubuntu as of Ubuntu 12.04 LTS. This post is meant as an overview of the work we did over the past 6 months and pointers to more detailed blog posts for some of the new features…”
“For quite a while now, libvirt has had an LXC driver that uses Linux’s namespace + cgroups features to provide container based virtualization. Before continuing I should point out that the libvirt LXC driver does not have any direct need for the userspace tools from the LXC sf.net project, since it directly leverages APIs the Linux kernel exposes to userspace. There are in fact many other potential users of the kernel’s namespace APIs which have their own userspace, such as OpenVZ, Linux-VServer, Parallels. This blog post will just concern itself solely with the native libvirt LXC support…”
“Lxc is great for starting up several containers on your laptop or on an ec2 host. But what if you want to fire up containers on multiple ec2 instances, and have them talk to each other?
An easy way to support that is using openvswitch. This script is a user-data-script which you can use to fire up instances ready to connect containers…”
“Containers provide lightweight virtualization that lets you isolate processes and resources without the need to provide instruction interpretation mechanisms and other complexities of full virtualization. In this step-by-step tour of the container tools called Linux® Containers (LXC), the author introduces you to the tools and shows how to get up and running on them…”
