Docker-compose "exec: \"/usr/src/app/entrypoint.sh\": permission denied"

This is based on https://testdriven.io/courses/microservices-with-docker-flask-and-react/

I'm running a docker file that will point to entrypoint.sh.

The docker-compose-f docker-compose-dev.yml build run successfully But running docker-compose-f docker-compose-dev.yml up shows

ERROR: for users  Cannot start service users: OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"/usr/src/app/entrypoint.sh\": permission denied": unknown
ERROR: Encountered errors while bringing up the project.

I did try to run on interactive mode with docker run -it –tty users_app:latest sh. Running ./entrypoint.sh did work. But it didn't work with docker-compose.

Does anybody have the same issue?

This is my docker-compose-dev.yml, Dockerfile-dev, and entrypoint.sh
