Hi  
I'm strangling how to change repo for track to local track. I'm trying to load rally benchmark on simply test "--track-path=/rally/.rally/nyc\_taxis"  
so I've mapped volume with above patch and changed path in track.json  
but getting error log that it's not possible

```auto
[INFO] Race id is [0036bcbb-8bfd-4f96-9391-04af02039ba0]
[ERROR] Cannot race. Error in task executor
        Not supported URL scheme file

```

Hello!

Could you provide the full docker command you are using to start up the container?

What platform is the docker host?

Presuming you have mapped a local folder to the docker container at /rally/.rally , does that folder contain the nyc\_taxis folder?

Thanks

Gareth

I'm used below command: (yes local folder is mapped to /rally/.rally)

```auto
docker run --rm --user root --name esrally_perfomance -v /home/elasticsearch/rally-tracks-master:/rally/.rally/ af2.my_repo/elk/rally:latest race --track-path=/rally/.rally/nyc_taxis --target-hosts=http://nginx_es:9500 --pipeline=benchmark-only --client-options="timeout:60,use_ssl:false,verify_certs:false,basic_auth_user:'rally',basic_auth_password:'pass'"

```

```auto
docker --version
Docker version 26.0.0, build 2ae903e

```

```auto
cat /etc/redhat-release
AlmaLinux release 8.6 (Sky Tiger)

```

so I have change base-url in that track.json to

```auto

Ah i see what you're trying to do.

The Error you are getting is coming from urllib3, which we use to parse the schema - [urllib3/src/urllib3/exceptions.py at main · urllib3/urllib3 · GitHub](https://github.com/urllib3/urllib3/blob/main/src/urllib3/exceptions.py#L196)

You're just wanting to use already downloaded files, instead of downloading each time?

There's two options from what I can see:

1. instead of mounting the track directory to .rally, have a folder structure as follows: (this option uses the standard rally directory structure, which may avoid other unknown issues later in the benchmark

/home/elasticsearch/.rally/benchmarks/data/nyc\_taxis \<---- Add your documents.json.bz2 etc here,  
/home/elasticsearch/.rally/benchmarks/tracks/default \<--- Add your track repo here, without your changes to base-url.

Then update the mount to -v /home/elasticsearch/.rally:/rally/.rally/

1. Instead of modifying the directory structure, you should be able to remove the base\_url component completely, and then test. if the files are there in the same directory as the track.json, rally should then pick it up and use them.

Try that and let me know how you get on 🙂
