О чем говорит ошибка отсутствия /var/run/containerd/containerd.sock ?
Первая тестовая установка kubernetes.
Firewall, swap отключены.
Сразу после установки сервис запустился
amk:~ # kubectl get nodes
NAME STATUS ROLES AGE VERSION
amk NotReady control-plane 4m17s v1.25.4
но после перезагрузки (в преднастройках потребовал 2 виртуальных ядра) перестал запускаться
# kubectl get nodes
The connection to the server 192.168.29.65:6443 was refused - did you specify the right host or port?
в логе ошибка failed to connect
и отсутствие файла /var/run/containerd/containerd.sock
