Expose MongoDB replica set from catalog outside of rancher #438

Open occasl opened 7 years ago

Has anyone had experience exposing the MongoDB replica set that you can build from the community catalog to clients outside of Rancher? I need a shared instance and this seems like an ideal way to quickly spin up instances, but I have no clue how I can expose the master from the replica set. You can't use an LB because it will roundrobin between each node in the replica set, which doesn't work well in Mongo since it's master/slave (unless you override that but that's not recommended).

Maybe there's some special sauce with HAProxy that can discover which one is master and have affinity toward it but I'm just not sure. This looked promising but I couldn't get that to work in the extra config section. Any ideas?

Also, how do I turn on authentication after I create the user account?

Hello, I have been trying to find a solution for several days but I have not been successful.

From inside it works smoothly and from outside only to individual nodes.

Did you find any solution to connect to full replica set?
