mongodb-replicaset doesn't create user

[jengo]

Bug report:

I am trying to setup authentication with mongodb-replicaset. The admin user never gets created.

Helm and tiller version: 2.6.2
Kubernetes version: 1.7.6 (In GKE)
mongodb-replicaset chart version: 1.4.1

What happened:

I ran the command

helm install --set auth.enabled=true,auth.adminUser=test,auth.adminPassword=test,auth.key=test123 stable/mongodb-replicaset

What you expected to happen:
When I ran db.getUsers() on the cluster it returned no users.

How to reproduce it (as minimally and precisely as possible):

helm install --set auth.enabled=true,auth.adminUser=test,auth.adminPassword=test,auth.key=test123 stable/mongodb-replicaset

Anything else we need to know:
I've also tried this on minikube v0.22.3 and get the same behavior.

I realized this was my fault. The admin user that is created only has access to the admin database.

Here is some additional information on troubleshooting for anyone searching for a solution.

MongoDB shell version v3.4.9

If you connect with the admin database specified, it works as expected:

root@test1-mongodb-replicaset-0:/# mongo admin -u test -p test --eval 'db.getUsers()'
MongoDB shell version v3.4.9
connecting to: mongodb://127.0.0.1:27017/admin
