i’m trying to setup a replicat between 3 MongoDB instance in a Docker environnement. All instances of MongoDB seems to works well. I’m able to be connected to thoses instances with Compass. The replicat seems also to works, a primary is elected and nothing in the logs altert me of a potential problem.
Here is the rs.conf() output:
{

I have added w=majority in the URI but nothing new. I think I have misunderstood the way to connect to the replica via MongoDBCompass, I’m using this URI :
mongodb://******:******@XX.XX.XX.XX:30001/?replicaSet=rs0&directConnection=true&authMechanism=DEFAULT&authSource=admin&w=majority
But shouldn’t I use this URI with the 3 MongoDB instances ?
mongodb://******:******@XX.XX.XX.XX:30001,XX.XX.XX.XX:30002,XX.XX.XX.XX:30003/?replicaSet=rs0&authMechanism=DEFAULT&authSource=admin&w=majority
When i try this URI, I have this error :
getaddrinfo ENOTFOUND mongo1
Here are the logs :
