Btw since you mention SQLite, the k3s system uses SQLite instead of the default etcd used by Kubernetes, for the reason you mention. These systems really are intended to support true edge scenarios. K3s is distributed as a single 40 MB binary, and you can run it on non-PC edge hardware.
For anyone who runs a system that involves multiple containers on a single machine, it can be worth looking at systems like k3s as an alternative to e.g. Docker Compose. There's not much downside other than some learning curve, and it gives you a wealth of capabilities that you otherwise tend to end up hacking together with scripts or whatever.
