Gregory's Server@stefano very interesting post! We've been using FreeBSD for a couple of years now mostly for crucial services (aka too important to ever fail), and I couldn't be happier.
On the other hand, looking at what k8s has given us for day to day production workloads, it is mostly the DevOps/GitOps part. Can you apply GitOps principles to the jails based approach you outlined in your blog post?
@riaschissl thank you! It can surely be done - but some more manual work, depending on what you need.
