A lot of the cgroups and namespaces functionality too time to mature and stabilize. User name spaces for instance was only available with 3.8. Cgroups and namespaces still don't play well with each other. Cgroups was initially added by

Just playing with this in a VM with an attached btrfs volume, a complete revelation. 96 lines! And it's actually pretty functional. This takes keeping it simple to a whole new level. The Wheezy image I use with LXC worked well enough,

That's why I used the word took, Docker used LXC as a base till version 0.9, untill it got enough traction, at which point it basically recreated LXC with libcontainer. But that was not the point. The point is you have always had perf

OpenVZ or LXC give you OS containers like KVM or VMWare gives your Virtual machines. Unlike OpenVZ, LXC does not need a custom kernel, and is supported in the mainline Linux kernel paving the way for widespread adoption. Docker took the LXC

Are you referring to the fdb tables, I tried that some months ago but it didn't seem to work. Maybe its changed now. I will give it a shot. Any tips? I remember seeing a patch floating around that added support for multiple default des

This looks unbelievably simple, on the lines of why hasn't it been done before. So you ping 10.3.4.16 and your host automatically 'knows' to just send it to 17.16.4.16 where lying in wait, the receiving host simply forwards i

Hi, I think we are playing with words and context here so I will leave it here. The quote is in a context and says LXD uses LXCs low level api. It does not say 'LXC is a low level api'. How does one conclude that from the quote an

No, I was referring to LXC. Did you have look at the links to the LXC website and the container overview? There are plenty of 2 minute screencasts there that show LXC in action. The LXC project does not refer to itself as low level, but ir

That's just wrong. Please have a look at the LXC or Systemd nspawn websites [1] or our guide to container technology [2] LXC is not 'low level' capabilities as Docker erroneously refers to it on its website or a 'low lev

Docker is an opinionated way to use containers. You don't need to adopt that to get the benefits of containers. A lot of the messaging, hype and marketing conflates the 2 and it suits the docker ecosystem to do that but it does not ben

LXC is really quite simple and makes a lot of sense when you need a lightweight VM, that behaves like a VM. Docker takes a very specific view of containers with layers, a modified container OS template and init that limits the container to

Container networking is not special or different from VM networking. There are tons of proven and widely used technologies available in the open source ecosystem. We have been building out a series of networking tutorials at flockport from

LXC is generic container technology like KVM OR Xen are generic virtualization technologies. LXC virtualizes the OS environment and gives you lightweight containers that you can seamlessly transition your VM workloads to, or use as a lightw

This is what normal LXC containers has always done. Systemd nspawn does not yet provide a toolset to wrap these capabilities like the LXC project. Things like userland tools, library of OS templates for containers, networking, features lik

Hi, Thanks for your comments. It's nice to hear from someone who is well informed and can tell the difference. Unfortunately as any container thread on HN itself will show and a lot of persistent questions we get on flockport.com confi

An app container is pared down to run a single app. That's why you need a third party process managers like runit, supervisor or a script to run multiple apps in a single app container format like Docker. A system container is similar

The persistent misconception about containers on hackernews is unfortunate. The open source Linux container project (LXC) dates 2009, has been supported by Ubuntu since 2012, and has mainly been developed by Stephane Graber and Serge Hallyn

This is actually quite similar to using LXC containers to run GUI apps. Something like Wine would be a good candidate to run in a container, perhaps others too. And you can use both privileged and unprivileged containers for this. I have a

Or it could mean as a funded company Docker has more resources than a low profile open source project like LXC to reach out and generate interest and adoption. There is undeniable confusion about LXC and Docker with a lot of folks whose fir
