ProModern take on cluster management via a GRPC api. Strong security focus.system modify/update with rpm-ostreeThe first OS that runs a stripped down Kubernetes binary as PID1. A great option for Raspberry Pi's and other edge devices.Fork of CoreOS - trying to continue on the original philosophies and provide a seamless transition from the original project.commercial backed, all K8s provision based on RKE - written in goBuild time management of immutable Kubernetes clusters.Designed to run on ESX.

Conlimited documentation, failed on ssh keys provision and no password resetK3s is aimed at Edge, IoT, CI and ARM. Not a full Kubernetes distro so not suitable for generic production cloud clusters.
No built in support for networking with bridge or vlan/lacp
New company, unsure how long development efforts and support will be provided.
Same as FedoraCoreOS, uses ignition
Changing go to modify provisioning ? This looks more like a PoC than something you'd actually run in production.The online docs are terrible. I gave up trying to find the details needed for this table.EOL: https://coreos.com/os/eol/
