I want to modify heartbeat-interval
of embedded etcd cluster running on kubernetes, I know while installation we can do with kubeadm extraargs but how to do in running cluster?
Before modifying I want to know current values too.
EDIT1: To get existing value use following
kubectl -n kube-system logs etcd-<NodeHostName> |grep heart
2021-06-25 11:08:31.612468 I | embed: heartbeat = 100ms
I also tried below but its not working for k8s.gcr.io/etcd:3.4.13-0
kubectl -n kube-system exec etcd-<NodeHostName> -- env|grep "ETCD_HEARTBEAT_INTERVAL"
