Unable to mount SQL Server ISO image inside my windows server core base image

Hi All,

I am relatively new to Docker and working on my first project. I am actually trying to install SQL server 2019 with the help of power shell scripts and using SQL Server ISO file (downloading it from azure blob storage in my docker file) on the top of windows server core base image. However, when I try to build the docker image , I get an error as attached. Could anyone please help me with this?
