All Docker containers start MongoDB version 4.4.6
That might happen from various reasons. Communication between all servers might take some time.
It is not recommended. IP address might change, FQDN rarely. Also Mongster does not work well with IP address. Please take some time to configure your hostname and DNS. You might find it useful in future.
Well, you can see it encrypted in the panel but it is completely decrypted in database. The same goes for passwords or any sensitive kind of information.
You can run only 1 instance of Mongo on port 27017. It might look a bit greedy but it has good reasons in regards to cluster stability.
Yes. We're using internal one via key file. It is generated automatically when you add a new cluster. Auth file is stored in /data directory on the node.
All data are stored in /data directory.
There are some Mongo limits. You can have up to 50 nodes but only 7 voting members.
Arbiter does not need any extra performance. However it has to be running on separate node. In case your cluster is about to fall apart he might break election ties in a situation where there is an even number (2, 4, 6...) of MongoDB nodes.
Currently Mongster does not support any kind of configuration for sharded cluster.
