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.

This time around the repos have more visibly moved, bringing with them a new install target ‘docker-engine’, and the […]


Dockercon #2 is underway, version 1.7.0 of Docker was released at the end of last week, and lots of other new toys are being launched. Time for some upgrades.

BanyanOps have published a report stating that ‘Over 30% of Official Images in Docker Hub Contain High Priority Security Vulnerabilities’, which include some of the sensational 2014 issues such as ShellShock and Heartbleed. The analysis also looks at user generated ‘general’ repositories and finds an even greater level of vulnerability. Their conclusion is that images […]
