What exactly are you trying to edit?
If you really need to edit a file with a container, then you first should map that directory/file to the host system
You'll potentially break the container if that file/container doesn't auto-generate on first run, and it's not recommended if you don't know what your are doing - as host-mapped files can become incompatible with container updates
