Just moved my stuff over from my old VPS to a new one on a different provider. In the process, also switched over to flatcar linux with my stuff running on containers. Much cleaner setup now, and easier to maintain!
Yes I know CoreOS and also read about the relationship to Flatcar. But I never tried it and wonder what the difference is that I need a whole distribution instead of some packages that allow you to run containers like executables?
For me the benefit is lesser maintenance. There's basically nothing on the host OS to maintain or update. I only have to worry about the container images, which is the case on any other host OS too. I'm sure there are other benefits, especially with more complicated usecases - I just run a couple of services for myself on this one.
