Answer 1

Go to project and click on docker-compose.yml

version: '2'
services:
    web:
        build: .
        ports: 
            - "8000:8000"
        volumes: 
            - .:/app
        links: 
            - db
            - mail-server
    db:
        image: "postgres"
        environment: 
            POSTGRES_PASSWORD: hunter2
        ports:
            - "5432:9432"
    mail-server:
        image: "mailhog/mailhog"
        expose: 
            - 1025
        ports: 
            - "8026:8026"

" change the ports to 8026:8026 because there is already running another container on this port number only change the port number"
