benchkv 如何测试tidb-docker-compose单机版？

[softarts]

通过https://github.com/pingcap/tidb-docker-compose.git 建立的集群，mysql登录没问题, docker ps -a

700ea5b3d197        pingcap/pd:latest            "/pd-server --name=p…"   4 hours ago         Up 4 hours          2380/tcp, 0.0.0.0:32771->2379/tcp                   tidb-docker-compose_pd0_1

于是我用benchkv -pd localhost:32771， 但是报错：

TiDB docker 只有 TiDB 的端口对外暴露了，你 benchkv 在外面是无法连接 PD 和 TiKV 的。需要做的是将 benchkv 放到同一个 docker compose 下面，参考 https://github.com/tikv/tikv/blob/master/docs/how-to/deploy/using-docker-compose.md#example
