Steps to reproduce the problem:

  1. Deploy mongodb-atlas service - app1
    acorn run -n app1 . --clusterName santest1 --dbName test1 --dbUser testusernew --provider AWS --region US_WEST_2
  2. Deploy consuming app - consumingapp1 for app1 . Make sure consuming app is able to connect successfully to DB.
  3. Deploy another mongodb-atlas service - app2 using the same clusterName and dbUser but different dbName
    acorn run -n app2 . --clusterName santest1 --dbName test3 --dbUser testusernew --provider AWS --region US_WEST_2
  4. Deploy consuming app - consumingapp2 for app2 . Make sure consuming app is able to connect successfully to DB.
    After this,

Try to make a DB connection from consumingapp1 (from step2). DB connection starts failing:

Changing the DB name is not really a supported use case. You end up creating orphaned databases that will get deleted when you remove the acorn.

There was a bug however, so the @{DB_NAME} should now be whatever the correct value is.

@cloudnautique In this use case , i am not updating an existing service with a different DB name. I am creating a new service with same clusterName and dbUser(as existing service) but different dbName which results in the existing service to have DB connection errors.

This should be resolved now. A username is generated based on the Acorn and Project names.
