docker, mount container folder to host

I need mount container's folder to host with all content from container.

In the container, there is this folder and there are a lot of files.

/u01/app/oracle/product/19.3.0/dbhome_1

On my host, I have this empty folder.

/opt/oracle/ohome

I need mount folder /u01/app/oracle/product/19.3.0/dbhome_1 from container to host folder /opt/oracle/ohome, with all his content.

I need use files from container on host.

I tried this (and with source/target path changing too).

docker run -d -p 1521:1521 --shm-size=3g --name oracle -v /opt/oracle/ohome:/u01/app/oracle/product/19.3.0/dbhome_1 IMAGE

I tried with bind too, but no success, folder is empty in every case.

How can I do that?

Thanks.
