How to backup etcd on a Kubernetes cluster created with kubeadm - rpc error: code = 13

I have a K8s cluster created with kubeadm that consists of a master node and two workers.

I am following this documentation article regarding the etcd backup: https://ku

Answer 1

I managed to make it work adding the certificates info to the command:

ETCDCTL_API=3 etcdctl --endpoints https://127.0.0.1:2379 --cacert=/etc/kubernetes/pki/etcd/ca.crt --cert=/etc/kubernetes/pki/etcd/healthcheck-client.crt --key /etc/kubernetes/pki/etcd/healthcheck-client.key snapshot save ./snapshot.db
