我正试图使用Rally文档页面中的说明从现有的Elasticsearch集群创建一个自定义轨道。
我以Docker Image的身份运行Rally。我正在运行elasticsearch:7.12.0以及同一主机中的docker映像。docker容器正在运行，可以使用基本的auth访问主机。
$ sudo docker container ls

"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},

}
当我尝试使用--client选项执行create-track命令时，我会得到下面提到的ConnectionError。
$ sudo docker run elastic/rally create-track --track=mytrack --target-hosts=localhost:9200 --client-options="timeout:60,use_ssl:false,verify_certs:false,basic_auth_user:'elastic',basic_auth_password:'esbackup-password'" --indices="my-index-local-*" --output-path=~/tracks

从错误中可以清楚地看出，在docker容器中运行的Rally无法创建与在单独容器中运行Elasticsearch的连接。我正在传递凭据--客户端选项，但这些选项似乎没有被选中。
不确定，我在这里做错了什么！任何建议都将不胜感激！
感谢Elastic团队在他们的官方讨论频道上回答了这个问题
该设置需要配置一个docker网络，并在Elasticsearch和Rally容器之间共享，以便它们进行通信。
我们在这里没有说明您的Elasticsearch容器是如何运行的，但一旦我们用网络执行它，我们就可以用以下内容运行集会(前提是您替换网络和容器名称占位符(：
$ docker run --network <es-network-name> elastic/rally create-track --track=mytrack --target-hosts=<es-container-name>:9200 --client-options="timeout:60,use_ssl:false,verify_certs:false,basic_auth_user:'elastic',basic_auth_password:'esbackup-password'" --indices="my-index-local-*" --output-path=~/tracks
