I installed mongodb using Helm in my Kubernetes cluster. https://github.com/kubernetes/charts/tree/master/stable/mongodb

It works fine and lets me connect to the db. But I cannot do any operation once I log into the mongo server. Here is the error I get when I try to see the collections.

    > show collections;
2018-04-19T18:03:59.818+0000 E QUERY    [js] Error: listCollections failed: {
    "ok" : 0,
    "errmsg" : "not authorized on test to execute command { listCollections: 1.0, filter: {}, $db: \"test\" }",
    "code" : 13,
    "codeName" : "Unauthorized"
} :

I am logging in as the root user using

mongo -p password

I don't know why even the root user has no authorization to do anything.
