Restored gitlab data missing after restarting docker.

Whenever I restart the docker and try to login to Gitlab it cannot check for my account. I believe the database data were gone everytime I restart docker. But whenever I restore the backup I can login and the data were fully restored.

Anyone who encountered this issue?

I can create backup using this command:

docker-compose run --rm gitlab app:rake gitlab:backup:create

and I restore the backup using this command:

docker-compose run --rm gitlab app:rake gitlab:backup:restore BACKUP=123456789

here's my docker-compose.yml

version: '2'

Start with docker-compose.yml and inspect the PostgreSQL and GitLab volume mappings, especially /srv/docker/gitlab/postgresql and /Users/techx/gitlab/gitlab/. Review the backup and restore commands shown in the issue, then reproduce a Docker restart and login attempt. Done means the GitLab account and database data remain available after restarting Docker without restoring a backup.
