With the release of LXC 2.0 and LXD, we now have a pure-container hypervisor that delivers bare-metal performance with a standard Linux guest OS experience. Very low latency, very high density, and very high control of specific in-guest application processes compared to KVM and ESX make it worth checking out for large-scale Linux virtuali

This is the sixth blog post in this series about LXD 2.0.Remote protocolsLXD 2.0 supports two protocols:LXD 1.0 API: That’s the REST API used between the clients and a LXD daemon as well as between LXD daemons when copying/moving images and containers.Simplestreams: The Simplestreams protocol is a read-only, image-only protocol used by bo

Recently, LXD stopped depending on lxc, and thus moved to using its own bridge, called lxdbr0. lxdbr0 behaves significantly differently than lxcbr0: it is ipv6 link local only by default (i.e. there is no ipv4 or ipv6 subnet configured by default), and only HTTP traffic is proxied over the network. This means that e.g. you

This is the fifth blog post in this series about LXD 2.0.Container imagesIf you’ve used LXC before, you probably remember those LXC “templates”, basically shell scripts that spit out a container filesystem and a bit of configuration.Most templates generate the filesystem by doing a full distribution bootstrapping on your local machine. Th

I’m in San Francisco this week, attending Microsoft’s Build developer conference, as a sponsored guest of Microsoft.That’s perhaps a bit odd for me, as I hadn’t used Windows in nearly 16 years.  But that changed a few months ago, as I embarked on

This is the fourth blog post in this series about LXD 2.0.Available resource limitsLXD offers a variety of resource limits. Some of those are tied to the container itself, like memory quotas, CPU limits and I/O priorities. Some are tied to a particular device instead, like I/O bandwidth or disk usage limits.As with all LXD configuration,

This is the third blog post in this series about LXD 2.0.As there are a lot of commands involved with managing LXD containers, this post is rather long. If you’d instead prefer a quick step-by-step tour of those same commands, you can try our online demo instead!Creating and starting a new containerAs I mentioned in the previous posts, th

This is the second blog post in this series about LXD 2.0.Where to get LXD and how to install itThere are many ways to get the latest and greatest LXD. We recommend you use LXD with the latest LXC and Linux kernel to benefit from all its features but we try to degrade gracefully where possible to support older Linux distributions.The Ubun

This is the first blog post in this series about LXD 2.0.A few common questions about LXDWhat’s LXD?At its simplest, LXD is a daemon which provides a REST API to drive LXC containers.Its main goal is to provide a user experience that’s similar to that of virtual machines but using Linux containers rather than hardware virtualization. How

As we are getting closer and closer to tagging the final releases of LXC, LXD and LXCFS 2.0, I figured it would be a good idea to talk a bit about everything that went into LXD since we first started that project a year and a half ago.This is going to be a blog post series similar to what I’ve done for LXC 1.0 a couple years back.The topi

I’ve been itching to write this post since I got back from Config Mgmt Camp in Gent a few weeks ago. The developers over at Canonical are gearing up to launch Juju 2.0. Maybe not yet a household name in the devops land but it is certainly making waves and with a company like Canonical

I had the opportunity to speak at Container World 2016 in Santa Clara yesterday.  Thanks in part to the Netflix guys who preceded me, the room was absolutely packed!You can download a PDF of my slides here, or flip through them embedded below.I’d

Introduction The LXD and AppArmor teams have been working to support loading AppArmor policies inside LXD containers for a while. This support which finally landed in the latest Ubuntu kernels now makes it possible to install snap packages. Snap packages … Continue reading →

In my last post, I introduced you to Juju and talked about how it could help you. Now I’d like to walk you through some real world examples of Juju in action. Workloads Bundles are used to represent workloads. Bundles can be simple, like the WordPress example in the previous post, or complex. OpenStack If

The team I am a part of at Canonical has been working on implementing a Juju provider for LXD. One of the goals of this provider is to improve the Juju experience when working and developing locally. You can try it yourself, but you will have to build Juju from source, the branch is available
