Inconsistent connection parameters in credentials settings for smooth migration

[leo-ri]

An old project could have difficulties with the connection if they move from mongodb-odb to atlas broker

With the old broker app uses environment variables (VCAP_SERVICES): { "mongodb-odb": [{ "label": "mongodb-odb", "provider": null, "plan": "standalone_small", "name": "test4", "tags": ["mongodb"], "instance_name": "test4", "binding_name": null, "credentials": { "database": "default", "password": "password", "servers": ["10.0.9.9:28000"], "ssl": false, "uri": "mongodb://username:password@10.0.9.9:28000/default?authSource=admin", "username": "username" }, "syslog_drain_url": null, "volume_mounts": [] }] } And the users have the possibility to use either uri or set parameters using servers/users/pass/etc for connection

If we install app with Atlas, we will have something like: { "mongodb-atlas-aws": [{ "label": "mongodb-atlas-aws", "provider": null, "plan": "M10", "name": "aws-test", "tags": [], "instance_name": "aws-test", "binding_name": null, "credentials": { "username": "username", "password": "password", "uri": "mongodb+srv://ca6aaf79-5741-4ba0.xqzpq.mongodb.net"
}, "syslog_drain_url": null, "volume_mounts": [] }] } As we can see, the users would have to rewrite their apps for making them work again: if uri was used for connection then we do not have user/pass/defaultdbname ( connection documentation mongodb://[username:password@]host1[:port1][,...hostN[:portN]][/[defaultauthdb][?options]] Also, we could use format (ruby, probably some other languges/libraries) client = Mongo::Client.new( credentials["servers"], :database => credentials["database"], :user => credentials["username"], :password => credentials["password"], :auth_source => "admin" )

In the end, I believe our credentials should be similar, otherwise, this will lead to fixing and pushing apps again. (let's not forget about if someone already uses atlas broker)
