4.x version. Initialization of replset and user creation problem.

[bimcas]

• Puppet: 5.5.19
• puppet-mongodb module version: v3.1.0
• MongoDB: 4.0.x and 4.2.x

I'm using puppet-mongodb module directly from https://github.com/voxpupuli/puppet-mongodb
:git => 'https://github.com/voxpupuli/puppet-mongodb.git'
:tag => 'v3.1.0'

What are you seeing

When I use MongoDB 3.x (3.4, 3.6) everything is OK. During installation of node I get just one warning:

Warning: Host is available, but you are unauthorized because of authentication is enabled: true

but everything is OK. Puppet successfully completes initialization of replset (primary) and all necessary users have been created:

[root@myhost.example.com ~]# mongo
MongoDB shell version v3.6.17
connecting to: mongodb://127.0.0.1:27017/?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("1d48b06f-1b16-4235-92a9-4c36ff9c1844") }
MongoDB server version: 3.6.17
mon-rep:PRIMARY>

Great!

So, when I'm trying to do the same with MongoDB 4.x versions (my hiera configuration of puppet is totally the same in all cases) the result is negative:

MongoDB shell version v4.2.6
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("0b21d660-4eca-4e13-a9ea-79c9ff33476d") }
MongoDB server version: 4.2.6
**Error: Authentication failed.**
>

So, initialization of replset (primary), authentication, and creation of users failed. So, MongoDB isn't prepared to use.

What behaviour did you expect instead

It would be great to get the same result with 4.x in preparation of MongoDB as I have with 3.x versions.

Thanks.

Does the anyone use this module with MongoDB 4.2 version? Is it everything is OK?

[epopoee]

Using this mod via Satellite 6.7 and MongoDB 4.2
Initialize a replset with auth enabled fails.

[DENISKI]

Can someone fix the issue. It's impossible to use the module with mongo 4.x enabling auth and replica set.

[dhs-rec]

Don't even need a replset. Can't setup admin user, database and database user here with auth enabled.

We have the same issue, but we found an kind-of acceptable workaround in comparison to what would have to change in the module.

Within a wrapper module we check it like so:

  if $facts['mongodb_is_master'] == 'not_installed' {
    $cluster_args = {}
  } else {
    create_resources('mongodb::db', $databases)

    $cluster_args = {
     # your actual config goes here
    }
  }

  class { '::mongodb::server':
    # all your config
    *  => $cluster_args,
  }

i don't understand what the values of $facts['mongodb_is_master'] can be

given the name, you'd think the value should be Boolean

Another dirty workaround during the first deployment run with 4.2:

• fact the primary in the mongo host array and ensure that there is no lock file
• stop the mongod
• start the mongod without authentication in a subshell
• create the admin user with db.createUser()
• kill the mongod process
• create lock file
• trigger new puppet apply
