Project: Allow MongoDB to run without authentication

[rassie]

There should be an option to run a MongoDB instance without authentication (I-know-what-I-am-doing kind of opt-in) to accomodate existing workflows e.g. in testing environments. The simplest way to do it would be to replace --auth with --transitionToAuth in the StatefulSet definition when some parameter is set on the CRD.

I have been able to workaround like this:

apiVersion: kubedb.com/v1alpha1
kind: MongoDB
metadata:
  name: test-mongodb
spec:
  version: "3.6-v1"
  replicas: 3
  replicaSet:
    name: test
  podTemplate:
    spec:
      args:
      - --transitionToAuth
  storage:
[...]

It results in both --auth and --transitionToAuth being on the command line, which doesn't seem to bother mongod, while it accepts the latest argument, which is --transitionToAuth, as intended.

Feel free to close the ticket since we now have a workaround. An actual implementation might make sense, but that's not for me to decide.

Adding my two cents here: this will work only with replica set. Trying this on single node will lead to this error: BadValue: --transitionToAuth must be used with keyFile or x509 authentication
