   - One possible idea is that we can change the existing process of reading YAML, and try to read environment variables once text in the format of `${}` such as `${SELF_JDBC_URL}` is detected.
   
   - Even now, there is a less intuitive way of doing it.  Since shardingsphere-jdbc-core comes with SnakeYAML 1.33, you can pre-write a YAML file or Template file that contains a series of `${}`, and then use SnakeYAML to read and replace this part of `${}` with other self-  Environment variable values ​​read with functions, and then serialized into YAML files required by shardingsphere-jbdc-core.  The process I am talking about is somewhat similar to the way nginx's docker image reads environment variables, refer to https://hub.docker.com/_/nginx .
   
   - I'm assuming you have another plan for submitting a PR.
