Example
Kubernetes (kubeadm)
ETCDCTL_API=3 etcdctl \
--cacert=/etc/kubernetes/pki/etcd/ca.crt \

Get Metrics from ETCD using curl
Note:
The
/etc/etcd/etcd.conf was actively used in OpenShift 3.x installations and some older Kubernetes deployment "methods".# Should you still have a `etcd.conf` source it
source /etc/etcd/etcd.conf
# Otherwise replace each `$ETCD_PEER_*` with the according path
curl --cacert=$ETCD_PEER_CA_FILE --cert=$ETCD_PEER_CERT_FILE --key=$ETCD_PEER_KEY_FILE -L https://127.0.0.1:2379/metrics -XGET -v
