Change database etherpad

Hello,
I use docker for jitsi-meet and etherpad.
Now I try to change the database of etherpad, but this not really works.
I started a mysql container and created the etherpad_lite_db with user etherpaduser.
Now I edited the database settings in settings.json.
I commented the section for dirtydb and uncomment the mysql section (changed user, password …).
Now its not possible to start the container.
Then I tried another way, I made the same changes but executed “node /bin/migrateDirtyDBtoRealDB.js”.
These are the Error messages:

internal/modules/cjs/loader.js:638
throw err;
^

Error: Cannot find module '/bin/migrateDirtyDBtoRealDB.js'
     at Function.Module._resolveFilename (internal/modules/cjs/loader.js:636:15)
     at Function.Module._load (internal/modules/cjs/loader.js:562:25)

     at startup (internal/bootstrap/node.js:283:19)
     at bootstrapNodeJSCore (internal/bootstrap/node.js:623:3)

Does anyone know whats the correct way to change the database?

Thanks to everyone, who try to help!

Nobody here who have a running etherpad in jitsi-meet based on docker?

I’m happy about any help :slight_smile:
