Running sitespeed and Graphite with Docker

Question

I am running graphite, graphana and sitespeed using docker using this link for my application website: https://www.sitespeed.io/documentation/sitespeed.io/performance-dashboard/#up-and-running-in-almost-5-minutes.

Also I am able to send the metrics to Graphana using the docker-compose command. I have few queries -

• docker-compose run sitespeed.io https://www.sitespeed.io/ --graphite.host=graphite - This command only runs for one URL. How do i run this for multiple pages/urls? On sitespeed documentation it is written that we can create a file url.txt with each url in the new line but that is not working. It says "urls.txt does not exist, is the path to the file correct?" Where should this url.txt resides in order to run

• This command starts the container and stops it. How so i remove those containers to improve the housekeeping because I will be running this every hour in crontab.

Below is my docker-compose.yml which i downloaded from above link
