rally可以通过docker镜像运行
使用Docker镜像时，不支持以下Rally功能：
- 分发负载测试驱动程序以应用多台计算机的测试。
- 使用
benchmark-only测试以外的其他 pipelines
您可以通过一个简单的命令列出可用的tracks来测试Rally Docker镜像
$ docker run elastic/rally list tracks

下一步，我们假设Elasticsearch在es01:9200上运行，并且可以从运行Rally Docker运行的主机上访问 使用以下命令在test-mode下运行nyc_taxis的tracks：
$ docker run elastic/rally --track=nyc_taxis --test-mode --pipeline=benchmark-only --target-hosts=es01:9200
现在，考虑到上述限制，您就可以使用所有常规的Rally命令。
Docker镜像的配置文件在/rally/.rally/rally.ini下,我们可以创建自己的配置文件并挂载使用：
docker run -v /home/<myuser>/custom_rally.ini:/rally/.rally/rally.ini elastic/rally ...
强烈建议将容器的/rally/.rally挂载出来，这将确保您在调用之间具有持久性，并且下载和提取的任何tracks都可以重用，从而减少了启动时间。
您需要确保UID为1000（尤其在OpenShift中，GID为0），以便Rally可以写入挂载的目录。
如果您的挂载文件中不包含rally.ini，则容器会在首次运行时为您创建一个。
例子：
mkdir myrally
sudo chgrp 0 myrally
# First run will generate the rally.ini
docker run --rm -v $PWD/myrally:/rally/.rally elastic/rally --track=nyc_taxis --test-mode --pipeline=benchmark-only --target-hosts=es01:9200

Running simple configuration. Run the advanced configuration with:
esrally configure --advanced-config
* Setting up benchmark root directory in /rally/.rally/benchmarks
* Setting up benchmark source directory in /rally/.rally/benchmarks/src/elasticsearch
Configuration successfully written to /rally/.rally/rally.ini. Happy benchmarking!

* Type esrally --help

* Ask a question on the forum at https://discuss.elastic.co/c/elasticsearch/rally
# now run our benchmark
docker run --rm -v $PWD/myrally:/rally/.rally elastic/rally --track=nyc_taxis --test-mode --pipeline=benchmark-only --target-hosts=es01:9200

万一您忘记挂载目录，Rally Docker镜像将为/rally/.rally创建一个匿名卷，以确保即使容器终止后日志和结果也能持久保存。 例如，执行我们之前的快速入门示例：
docker run elastic/rally --track=nyc_taxis --test-mode --pipeline=benchmark-only --target-hosts=es01:9200
docker volume ls
DRIVER VOLUME NAME
local 96256462c3a1f61120443e6d69d9cb0091b28a02234318bdabc52b6801972199
为了进一步检查内容，我们可以将其绑定到另一个镜像中，例如：
$ docker run --rm -i -v=96256462c3a1f61120443e6d69d9cb0091b28a02234318bdabc52b6801972199:/rallyvolume -ti python:3.7.3-slim /bin/bash
root@9a7dd7b3d8df:/# cd /rallyvolume/
root@9a7dd7b3d8df:/rallyvolume# ls
root@9a7dd7b3d8df:/rallyvolume/.rally# ls

{
"rally-version": "1.2.1.dev0",
"environment": "local",
"race-id": "1d81930a-4ebe-4640-a09b-3055174bce43",
Rally以用户1000的身份运行，其文件使用uid：gid 1000：0进行安装（以支持任意用户ID）。
您还可以在现有映像之上创建自己的自定义Docker映像。以下示例显示了如何入门：
FROM elastic/rally:1.2.1
COPY --chown=1000:0 rally.ini /rally/.rally/
然后，您可以使用以下命令构建和测试镜像：
docker build --tag=custom-rally .
docker run -ti custom-rally list tracks
