Description

I am encountering issues with my Docker Compose setup for an Ansible lab environment. Specifically, there are port conflicts when running multiple replicas of a service, and difficulties with fixed host port assignments for these replicas.

Environment

• Docker version: 24.0.7
• Docker Compose version: 1.29.2,
• OS: ubuntu 22.04

Steps to Reproduce

1. Run docker-compose up -d with the following Docker Compose configuration:
