Juju is all about modeling your application. That means that an application can be in a docker container, use a configuration management utility on top of a traditional machine, or is a single binary golang application. This is the beauty of abstracting via models; we can concentrate on the applications themselves instead of their deliver

Juju is Canonical’s service modeling and deployment tool. It supports a very wide range of cloud providers to make it easy for you to deploy any service you want on any cloud you want.On top of that, Juju 2.0 also includes support for LXD, both for local deployments, ideal for development and as a way to co-locate services on a cloud inst

IBM Systems Magazine Webinar “Discover the Cloud and Scale Out World of Ubuntu”held on 27 April 2016 Recently announced support for Ubuntu 16.04 LTS on IBM LinuxONE and z Systems has created a paradigm shift in a world that often does not see much change. Systems that cannot fail, systems that the world relies on,

Today Mesosphere announced the open source release of the DC/OS (Datacenter Operating System) Project, backed by dozens of partners including Canonical. DC/OS supplies an operating system model for the datacenter building on the Apache Mesos environment. The DC/OS project is an open source technology and a building ecosystem of more than

The next post in the LXD series is currently blocked on a pending kernel fix, so I figured I’d do an out of series post on how to use the LXD API directly.Setting up the LXD daemonThe LXD REST API can be accessed over either a local Unix socket or over HTTPs. The protocol in both case is identical, the only difference being that the Unix

I’m thrilled to introduce Docker 1.10.3, supported on every Ubuntu architecture, for Ubuntu 16.04 LTS, and announce the General Availability of Ubuntu Fan Networking!That’s Ubuntu Docker binaries and Ubuntu Docker images for:armhf (rpi2, et al. IoT devices)arm64 (Cavium, et al. servers)i686 (does anyone seriously still run 32-bit intel se

This is the eighth blog post in this series about LXD 2.0.IntroductionIn the previous post I covered how to run Docker inside LXD which is a good way to get access to the portfolio of application provided by Docker while running in the safety of the LXD environment.One use case I mentioned was offering a LXD container to your users and th

This is the seventh blog post in this series about LXD 2.0.Why run Docker inside LXDAs I briefly covered in the first post of this series, LXD’s focus is system containers. That is, we run a full unmodified Linux distribution inside our containers. LXD for all intent and purposes doesn’t care about the workload running in the container. I

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

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 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
