ETCD kubeadm getsockopt: connection refused

Question

I would like to use the etcdctl functionnalities of my etcd pod from my kurnetes cluster but I can't. I have install my kubernetes from kubeadm and I have 1 master and 1 node.

When I try commands etcdctl from inside of my etcd pod, I get those errors:

client: etcd cluster is unavailable or misconfigured;
error #0:malformed HTTP response "\x15\x03\x01\x00\x02\x02" ;
error #1: dial tcp 127.0.0.1:4001: getsockopt: connection refused

But when I check my etcd pod log, it seems healthy :

Answer 1

ETCDCTL_API=3 etcdctl --endpoints=localhost:2379 --cacert=/etc/kubernetes/pki/etcd/ca.crt --cert=/etc/kubernetes/pki/etcd/healthcheck-client.crt --key=/etc/kubernetes/pki/etcd/healthcheck-client.key member list
