If you believe in de containerised concepts and that containers should be immutable, certain parts of the configuration should be fixed as well. In the context op OpenHab, this means that you can’t add switches, sensors and actuators on a running instance of OpenHab, when you have already deployed your container or unikernel. When the configuration changes, a new container should be built and deployed. Applying immutable containers means that you’re deploying new images a bit more often than you would do when using mutable containers. And to make sure that this isn’t too painful, I have put Jenkins to this…

Mosquitto Unikernel using OSv and Capstan

Some time ago, I wrote a blog post about Unikernels and was quite enthousiast about the combination of OSv and XenServer. I had Cassandra running in an OSv container in a Jiffy and think Unikernels on hypervisors are quite better to manage and maintain than Docker images. If you want to know more about why I think they could be considered the successor of Docker, please do feel free to read my blog “Minimalist Cassandra VM using an OSv Unikernel“. In this blog I have written about my journey to get a unikernel Cassandra running, but I’m also trying to…
