@sukantoraymond, i don't think it's possible to make docker to create shared folders for us based on docker/compose#2781 (comment). It will be able to error out in case folder doesn't exists VS creating folder with root owner, but it's not possible to make docker create folders under user owner.

based on https://stackoverflow.com/questions/21889053/what-is-the-runtime-performance-cost-of-a-docker-container and https://unix.stackexchange.com/questions/604405/do-docker-container-cause-slow-disk-os-performance#:~:text=If%20you%20use%20a%20bind,performance%20overhead%20is%20near%20zero.

there should be no noticeable performance impact for disk as CPU/mem/network
