Error while creating replica set with name and auth args

[KozlovAV]

mlaunch init --replicaset --nodes 3 --name RS1 --hostname localhost --auth

will result in

replica set 'RS1' initialized.
waiting for primary to add a user.
Traceback (most recent call last):

KeyError: 'replset'

The problem in hardcoded replica set name ('replset') in line 1228

hosts = [x['host'] for x in self.config_docs['replset']['members']]
rs_name = self.config_docs['replset']['_id']

Maybe self.args['name'] should be OK

@KozlovAV Thanks for the bug report! Can you confirm which version of mtools you are using?

[KozlovAV]

mlaunch --version
