Learnings so far: 
    - how to ingest the external data to postgres db using python and its libraries.
    - how to spin up postgres db and postgres admin containers and place them in same network.
    - dockerize the parameterized python script and spin up container in the same network where we have postgres db.

    Additional Contribution:
    - Ehnaced the python script to handle multiple data sources with different file formats (gzip and csv) and read the source in csv format.
    - Handling the column data types conversion where ever applicable.
    - Developed the shell script to automate the docker commands for all data ingestion activities.
