We're using a new method (vault kv get) to get the admin passwords for our mongodb clusters, however, it gets the password without an EOF. This is fine for the mongo CLI, but not for mongodump.
For example, this works with the mongo cli:
# 'echo -n' simulates the password output from {{vault kv get}}
|
echo -n PASSWORD | mongo --host mongohost:27017 --authenticationDatabase admin -u admin --password '' --eval 'db.version()'
|
However, I get the following error when attempting to use mongodump with a password without EOF:
$ echo -n PASSWORD | mongodump --oplog --host configReplSet/mongohost:27019 --authenticationDatabase admin -u admin -p '' --out ~/backup.$(date +'%Y%m%d-%H%M')

Any chance both mongo and mongodump can handle passwords without EOF? For now we have a workaround.
Here's more information on Hashicorp's vault kv get:

Thanks,
