How to keep datas remain after switch to deocker for deployment(Wagtail into an existing Django project)

let me clear what is going on....... am working on wagtail project which is comes from ff this steps: -How to add Wagtail into an existing Django project(https://docs.wagtail.org/en/stable/advanced_topics/add_to_django_project.html)

and am try to switch project to docker for deployment and do not forget am "import sql dump into postgres", and am aim to run on uwsgi and everything is perfect no error;but there are problem after everything i can't see anything on pages and when i try to access admin there is no any existed pages(which means i should create pages from scratch)

here are some of cmds i used: -docker-compose -f docker-compose-deploy.yml build -docker-compose -f docker-compose-deploy.yml up -docker-compose -f docker-compose-deploy.yml run --rm app sh -c "python manage.py createsuperuser"

if it needed here is the Dockerfile:
