CodePudding user response：

I have't provided docker-compose.yml here. There was a mistake. The containers did't have a shared volume to access the socket together. Added volumes to both containers.

At the end of docker-compose.yml:

volumes:
    api_data:
    pgdata:

In the description of both containers:

        volumes:
        - api_data:/usr/src/app/
