Ok I am trying this again. I am not sure why my last questions were not answered. Please let me know if I am doing something wrong in asking them. Here they are again:
"Please explain "You'd have to manually change the docker-compose.yaml file to use the on-host database though." Even though I run docker-compose-mysql -d I still need to update the docker-compose.yaml file? See that is confusing for me. Again it is probably due to my inexperience in using docker."
I think that is a legitimate question. There are two files being referenced here. If docker-compose-mysql.yaml has the correct setup then why do I need to manually change the docker-compose.yaml? It seems both files perform the same function except one references a Postgre DB and the other a MySQL DB.
