For developing purpose, I need to create a standalone topology of mongodb. I’d like to use operator to build it, so I can reuse the same deployment way both for production and development. For what I’ve seen so far, replicaset mode is not switchable. Can you help me with this configuration?

Thanks

Hi @Alessandro_Rovetto !

You will need to set “allowUnsafeConfigurations: true” and set replica set size to 1.  
Although in this case you will get a replica set, but just with 1 node (primary) - not exactly the same as a standalone so not sure if it will be ok for your use case or not.  
I don’t think there’s a way to start true standalone with our operator.
