           1       2       3           4              5

Explanation for those who are struggling

1. you server static IP address
2. you exposed port no (any in one of the four user B when A->B)
3. your databasename this is what you enter while you run this command dokku mongo:create dbname
4 & 5. you will get this when running dokku mongo:info
