Is it Possible to configure Mongo db replica set in Hybrid environment. Primary server on VM and Secondary server on Containers

Ops and Admin Replication
#1

Hi,
Today we got query from one of our client related to replica set implementation. we are looking for the following Architecture:

==> Primary Server on VM.
==> 3- Secondary Servers (Replica) on Containers

Is it possible to have such Hybrid/heterogeneous environment?

Please guide.

The short answer is yes, granted you have all of your networking requirements/definitions/DNS sorted out.

I see no benefit to this architecture, mixing cattle and pets together. I would nudge them toward 100% Docker Compose or Kubernetes operator, based on scale requirements.

Thanks Allen,
do we have any official compatibility matrix from Mongo db?

#4

Not that I am aware of, but as long as the base version, OS distribution and the architecture is the same, it should work.

#5

Nobody ever cares where/how you run those servers (thanks to abstraction in VM/containers/hardware…), as long as they can be set up running and connect to each other.
