Run docker postrgessql image twice first exits - postgresql

Question

I made 2 yml and when i run docker-compose -f postgresql.yml up its starts ok
and then when i run docker-compose -f postgresql2.yml up first exist code 0.
Is it even possible to run same image twice?
My main purpose to run same web app source twice with different db on the same server pc.
1 web app source 2 instances with self db each on one server(maybe its clearer definition).
Maybe there is better approach and I do and think everything in wrong way.
# This configuration is intended for development purpose, it's **your** responsibility to harden it for production
version: '3.8'
services:
freshhipster-postgresql:
image: postgres:13.1
environment:
- POSTGRES_USER=FreshHipster
- POSTGRES_PASSWORD=
- POSTGRES_HOST_AUTH_METHOD=trust
# If you want to expose these ports outside your dev PC,
# remove the "127.0.0.1:" prefix
ports:
- 5432:5432
and this no big difference
postgresql2.yml

Answer 1

Just use another service name freshhipster-postgresql2 on postgresql2.yml
version: '3.8'
services:
freshhipster-postgresql2:
image: postgres:13.1
container_name: postgres2
volumes:
- pgdata:/var/lib/postgresql/data_vol2/
environment:
- POSTGRES_USER=FreshHipster
- POSTGRES_PASSWORD=
- POSTGRES_HOST_AUTH_METHOD=trust
# If you want to expose these ports outside your dev PC,
# remove the "127.0.0.1:" prefix
ports:
- 5433:5432
volumes:
pgdata:
external: true
