Username password should not be checked into git

[Ameya05]

Docker username password should be tokenized via Travis-CI or Encrypted perhaps instead of being present in the code commits on git

Didnt work using tokens configured in Travis-CI

Might have to

1. Encrypt password
   or
2. Use token Replacement scripts

I did try to create a .env file to store passwords. But it didn't seem to work as I expected. Can we remove read permissions to the script? We are anyway using it only to deploy the files, right?
