Mostly based on https://github.com/teran/docker-yandex-disk
Since yandex-disk CLI utility has a creepy feature to spontaneously upload your files and images outside of its data folder, i've decided to put it into a restricted container.
Use the provided yandex-disk-docker.sh script to start a dokerized yandex-disk and link it to its config and data dirs on a host machine.
