Hello,
It is a known issue wich has not direct and easy solution because it is binded on how docker is created (that doesn't rely on Container app development from rexroth, we're just using that). I also tried myself to let this working with no results, i forward again the question to the developers.
Docker is a SW tested and designed to be cloud based with almost illimited storage See: Docker and diskspace . CtrlX core X3 can definitely running Docker images but it depends on how much this image is big, there is no yet a benchmark.
To use more resource hungry Images is better to wait for the x7 controller.
Any app that contains the removeble-meda plug can use an external memory mounted as removable media and then write to /media/yourmediadevice.
