Dashboard installation

[NPhGit]

I've apisix install and run fine then I need to install dashboard as guide
https://apisix.apache.org/docs/dashboard/install/

docker pull apache/apisix-dashboard
docker run -d --name dashboard
-p 9000:9000
-v <CONFIG_FILE>:/usr/local/apisix-dashboard/conf/conf.yaml
apache/apisix-dashboard

Please replace <CONFIG_FILE> to your configure file path.

How can I get/know this "<CONFIG_FILE>" string?
Note: Running apisix on Ubuntu 22.04.1 by https://run.api7.ai/apisix/quickstart
