However, if you are just dealing with a three node cluster (Yes I know many of you are running tri-cycles with k8s stickers on it) then maybe it can be fine for many applications to not have a scheduler.
Simplenetes does however support multiple replicas of pods so if one node fails it can be OK.
If you want something simpler and use podman you can try `podc` [1] which compiles a pod yaml spec into a single executable shell script with a nice managagement CLI api to it.
