Help setting up Rally for Performance Benchmarks

I am trying to setup rally using the docker image rally:2.2.1

When trying to list the tracks, i get this error. How do i get around it.

[WARNING] No Internet connection detected. Automatic download of track data sets etc. is disabled.
[ERROR] Cannot list. Expected a git repository at [/rally/.rally/benchmarks/tracks/default] but the directory does not exist.

Hi, think this is a better match for our Elasticsearch discuss , here are topics about rally:

https://discuss.elastic.co/tags/c/elastic-stack/81/rally

Best,

I was not able to create post under rally, it says you are not permitted.
Any idea how to get access.
