When directly building with dockerfile, the general report cannot connect to the database. I don't know why. Please help me see, or how to build the official docker image

docker-compose. XML is the content of the following file. Dockerfile is the content pulled from GIT

pgsql:
image: "postgres:13"
volumes:
- "./dataCusdis:/var/lib/postgresql/data"
environment:
- POSTGRES_USER=cusdis
- POSTGRES_DB=cusdis
- POSTGRES_PASSWORD=password
cusdis:

I think it's because you didn't expose the 5432 port in the compose file?
