Hey; Linux refugee here. I want to have a bunch (5-10) of freebsd cattle-style servers to run a service on. What’s the preferred infrastructure as code style approach to setting them up? Some will be bare metal with kvm console access. Some will be VMs. They will be heterogeneous and not in one DC. I probably don’t need zfs for this application (raw iops matter more than snapshots, etc). I have previous experience with kubernetes, and am not interested in using it again. Monitoring, logging, deterministic “zero to working” install and updates are probably the main requirements.
