I have tried to run mongodb replicaSet in local with mongoldb-community in my Mac I follow mongodb doc I can run it by this command 

mongod --port 27017 --dbpath /usr/local/var/mongodb --replSet rs0 --bind_ip localhost,127.0.0.1

but it doesn't run on background, so every time I want to start replica set mongodb I should run that command, before I run it I should stop mongo first, then on the next tab console I should run mongo --eval "rs.initiate()" to create to replicaSet again

here is my docker compose:

version: "3.7"
services:
  mongodb_container:
    image: mongo:latest
    ports:
      - 27017:27017
    volumes:
      - mongodb_data_container:/data/db

volumes:
  mongodb_data_container:

how to convert that into docker-compose ? is it possible ?

can I do docker exec CONTAINER_ID [commands] ? to run command mongo like above , but must stop the mongodb run in that docker ?

dockerfile docker-compose docker mongodb

You can have a mongodb replica-set with this docker-compose services:

mongodb-primary:
    image: "bitnami/mongodb:4.2"
    user: root
    volumes:
      - ./mongodb-persistence/bitnami:/bitnami
    networks:
      - parse_network
    environment:
      - MONGODB_REPLICA_SET_MODE=primary
      - MONGODB_REPLICA_SET_KEY=123456789
      - MONGODB_ROOT_USERNAME=admin-123
      - MONGODB_ROOT_PASSWORD=password-123
      - MONGODB_USERNAME=admin-123
      - MONGODB_PASSWORD=password-123
      - MONGODB_DATABASE=my_database
    ports:
      - 27017:27017

  mongodb-secondary:
    image: "bitnami/mongodb:4.2"
    depends_on:
      - mongodb-primary
    environment:
      - MONGODB_REPLICA_SET_MODE=secondary
      - MONGODB_REPLICA_SET_KEY=123456789
      - MONGODB_PRIMARY_HOST=mongodb-primary
      - MONGODB_PRIMARY_PORT_NUMBER=27017
      - MONGODB_PRIMARY_ROOT_USERNAME=admin-123
      - MONGODB_PRIMARY_ROOT_PASSWORD=password-123
    networks:
      - parse_network
    ports:
      - 27027:27017

  mongodb-arbiter:
    image: "bitnami/mongodb:4.2"
    depends_on:
      - mongodb-primary
    environment:
      - MONGODB_ADVERTISED_HOSTNAME=mongodb-arbiter
      - MONGODB_REPLICA_SET_MODE=arbiter
      - MONGODB_PRIMARY_HOST=mongodb-primary
      - MONGODB_PRIMARY_PORT_NUMBER=27017
      - MONGODB_PRIMARY_ROOT_PASSWORD=password-123
      - MONGODB_REPLICA_SET_KEY=123456789
    networks:
      - parse_network
    ports:
      - 27037:27017

networks:
  parse_network:
    driver: bridge
    ipam:
      driver: default

  mongodb_master_data:
    driver: local
