Docker can be a headache at times, but being able to maintain a consistent environment is very handy. For the large binary resources (trained models, dataset, etc) I've found it easy enough to just use docker volumes to mount read only resources. Other people have resorted to leaving read only assets on the local network which might be fast enough for your needs. As long as you're not unintentionally copying data, mounting a TB of data read only takes no time in my experience.
