K3s – Lightweight Kubernetes
Agreed. Kubernetes (installed via kubeadm) on 1 GB of RAM is a shaky proposition at best; I've been managing a cluster on Raspberry Pis and the master often hits swap managing three Nodes with a dozen or so Pods.

K8s doesn’t support swap, you have to disable swap to even run kubelet.

There is an override flag.
It works, but it kind of invalidates all assumptions k8s makes about free memory on a node

What workloads are you running? With only 1gb, have you looked into setting resource limits for your pods?
