no port available, no flask-mongodb communication

[ndrini]

Hello Ishmeet,
I forked your project ( https://github.com/ndrini/PublicProjects/tree/hotfix/Python/MongoDB%20API ) and I discover several issues.

Please, have a look to branch hotfix.

1. In the docker-compose file was missing
   ports:
   - "5000:27017"
   so no port was exposed

2. no database initialization (no database IshmeetDB and collection people)

3. no communication (even if manually create the database) inside the container

   $ docker exec -it feb99612817c bash
   root@feb99612817c:/# mongo

   use IshmeetDB > db.createCollection('people')
   db.people.insert({ "First_Name": "Barbara", "Age": 66 })
   WriteResult({ "nInserted" : 1 })
   db.people.find()
   { "_id" : ObjectId("60519022e03abca730129cc9"), "First_Name" : "Artur" }
   { "_id" : ObjectId("60519044e03abca730129cca"), "First_Name" : "Barbara", "Age" : 66 }
   db.people.insert({ "First_Name": "Carl", "Age": 96 })
   WriteResult({ "nInserted" : 1 })
