Originally published internally 26 Jan 2016: Last week Docker Inc acquired Cambridge based Unikernel System Ltd, which has got a lot of people asking ‘what’s a unikernel?’, a question that’s well covered in the linked piece. Going back a few years I covered the launch of Mirage OS, which is the basis for what Unikernel Systems […]


At the recent DockerCon event in Austin Docker Inc announced two significant open source projects, Moby and LinuxKit. Moby essentially marks the split of Docker the open source project from Docker Inc the company, with the docker/docker GitHub repo moved to moby/moby. LinuxKit provides a set of tools to build ‘custom Linux subsystems that only […]


Originally posted internally 6 Jan 2016: I’d meant to post this before the Christmas break as a guide to things to tinker with over the break, but then I hit the point where pretty much everybody seemed to already be on leave, and it was clearly too late…. So Happy New Year, if you’re not already […]


Originally published internally 24 Dec 2015: Install Docker, because it gives you installation superpowers for many other things. Install Docker, so that you don’t have to install Ansible, or Python, or Golang, or Greylog, or pretty much whatever else you were needing to install. Install Docker, so that the next Yak you shave will be a […]

The release comes alongside an update to the CIS Docker Security Benchmark to bring it in line with Docker 1.11.0, and an updated Docker Bench tool for checking that host and daemon configuration match security benchmark recommendations. continue […]


Background The last two interviews that I’ve done for InfoQ have been with Anil Mahavapeddy and Bryan Cantrill, and in both cases we talked about unikernels. Anil is very much pro unikernels, whilst Bryan takes the opposing view. A long and rambling Twitter thread about oncoming architecture diversity in Docker images took a turn into the unikernel […]


Back in March I wrote about Using Overlay file system with Docker on Ubuntu – those instructions applied to Ubuntu before the switch to systemd e.g. 14.04 and earlier. The move to systemd means that changes to /etc/default/docker don’t have any effect any more. To get systemd to dance along to our tune needs a file like […]


“Installation is a Software Hate Crime” – Pat Kerpan, then CTO of Borland circa 2004. Today’s hate – meta installers I’ve noticed a trend for some time that when downloading an installer rather than being the 20MB or so for the actual thing I’m installing it’s just a 100KB bootstrap that then goes off and […]


On my first day with Bryan Cantrill he did a wonderful (and very amusing) presentation on Debugging Microservices in Production on the containers track at QCon SF. On my second day with Bryan Cantrill we talked about Containers, Unikernels, Linux, Triton, Illumos, Virtualization and Node.js – it was something of a geekfest[1]. On my third day with Bryan […]


Rising from the ashes of GigaOm the tribal gathering of cloud elders that is Structure has returned, and got off to a strong start with Battery Venture’s Adrian Cockcroft presenting on the State of the Cloud and Container Ecosystems. Cockcroft paid particular attention to the impact of containers, which wasn’t even a major discussion topic at […]
