I am reading the docker file of Kibana. Here is the link: [Kibana official docker file](https://github.com/elastic/dockerfiles/blob/8.11/kibana/bin/kibana-docker).
I noticed that the config can come into force by just set the environments. I've seen the annotation of its theory. But I do not know how to begin with it.

Can you give me some guidance of how to have a deeper understanding of this knowledge point. Thanks a lot.
