This issue is native for docker. Since when container binds volume to a directory of certain uid:gid (numeric), the binded volume would have the same . Refer to moby/moby#3124

And might be solved by manually bash into container as root, and following steps here https://stackoverflow.com/questions/42423999/cant--file-created-via-docker

1. docker exec -it --privileged -- root container_id /bin/bash
2. cd directory && rm -r * .*

but this method would cause container crash

docker image need to be built with sub user added. https://vsupalov.com/docker-shared-permissions/

this issue happened since we did not add users into images.

when we bash start.sh, and do start_db, there is a line docker run .... $VOLUME_MOUNTS, copies these sudo files into container
