hi @Han910
Welcome to Metabase Discourse.

Can you confirm if your MySQL instance also hosted on Docker?

Hi @bayo99

I am not sure about that. How can I check whether my SQL instance is hosted on Docker?
I created my database using Query in MySQL afterward installed docker and opened up the metabse.
Currently I run Metabase through docker but not the .jar

@Han910

How did you install the MySql instance?

I installed MySQL from the official MySQL website and configured it to run on my localhost with the default port 3306. Am I supposed to change it to host in docker?

Hi @Han910

Since you installed from the official MySql website, you can use your normal connection string to connect the metabase instance.
