Docker Container extension Oracle Linux:6

Hi All

I’ve been searching far and wide and I cannot find a way that I can extend my Docker container size to be greater than 10Gb, I am currently creating a container that installs Oracle Database 12c, however I have now hit space limits and keep getting told that I do not have enough disk space to install.

I am running Oracle Linux

Please note I am new to Linux and docker so sorry if this has been answered a million times
