etcdbenchmark 測試 etcd 叢集 === ## etcd 測試 * 分下列三種： * 線性讀取 * 序列化讀取 * 寫入 ### 線性讀取： * 取得k8s secrets key ```shell= kubectl get secrets ``` ![](https://i.imgur.com/vzyYvPJ.png) * 查看key.pem & .pem ![](https://i.imgur.com/QH8KsgT.png) * 跑etcd benchmark ```shell= docker run -v /opt/rke/etc/kubernetes/ssl:/ssl fangruo/etcd-benchmark:1.0 benchmark --cacert="/ssl/kube-ca.pem" --endpoints="$etcdip1:2379,$etcdip2:2379,$etcdip3:2379" --key="/ssl/kube-etcd-172-25-4-171-key.pem" --cert="/ssl/kube-etcd-172-25-4-171.pem" --conns=100 --clients=1000 range /registry/secrets/default/$secrets --consistency=l --total=100000 ``` ### 序列化讀取： ```shell= docker run -v /opt/rke/etc/kubernetes/ssl:/ssl fangruo/etcd-benchmark:1.0 benchmark --cacert="/ssl/kube-ca.pem" --endpoints="$etcdip1:2379,$etcdip2:2379,$etcdip3:2379" --key="/ssl/kube-etcd-172-25-4-171-key.pem" --cert="/ssl/kube-etcd-172-25-4-171.pem" --conns=100 --clients=1000 range /registry/secrets/default/$secrets --consistency=s --total=100000 ``` ### 寫入： ```shell= docker run -v /opt/rke/etc/kubernetes/ssl:/ssl fangruo/etcd-benchmark:1.0 benchmark --cacert="/ssl/kube-ca.pem" --endpoints="172.25.4.171:2379,172.25.4.172:2379,172.25.4.173:2379" --key="/ssl/kube-etcd-172-25-4-171-key.pem" --cert="/ssl/kube-etcd-172-25-4-171.pem" put --conns=100 --clients=1000 --key-size=8 --sequential-keys --total=100000 --val-size=256 ```
