Docker for oracle osm

I have requirement of Dockerizing Oracle OSM management system:

ORACLE OSM comprises of the following:

1.Weblogic domain server and managed server up and running.
2. running instance of oracle DB ,where some Table spaces needs to be created for ORACLE osm.

I know we have the Docker web logic image already in place where I can make use of it.

My query is ,Can I use a existing oracle host from weblogic containers ? if yes how can I use the same from running weblogic containers.

else

Do I have to create a oracle image to link with weblogic containers?

Please suggest me how I can design this
