Cheat Sheet

Check ETCD performance "status" quickly¶

3

ETCDCTL_API=3 etcdctl \
    [YOUR_FLAGS] \
    check perf

Example¶

Kubernetes (`kubeadm`)¶

ETCDCTL_API=3 etcdctl \
    --cacert=/etc/kubernetes/pki/etcd/ca.crt \
    --cert=/etc/kubernetes/pki/etcd/server.crt \
    --key=/etc/kubernetes/pki/etcd/server.key \
    check perf

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

Show ETCD Cluster Members¶

ETCDCTL_API=3 etcdctl \
    --cacert=/etc/kubernetes/pki/etcd/ca.crt \
    --cert=/etc/kubernetes/pki/etcd/server.crt \
    --key=/etc/kubernetes/pki/etcd/server.key \
    member list
