  and

  mongo:8

  .
  • redis service should have
    • password

      rootroot

    • mapping port 6379 to 6379
    • mounting volume

      ./redis_data

      to

      /data

  • postgresql service should have
    • password

      rootroot

    • mapping port 5432 to 5432
    • mounting volume

      ./postgres_data

      to

      root

    • initdb root password

      rootroot

    • mapping port 27017 to 27017
    • mounting volume

      ./mongo_data
