Hi,

I have deployed successfully the 3 nodes,

[root@localhost devcontainers-mongodb-replica-set-with-docker]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                    PORTS                      NAMES

However, if you try to connect using the replicaSet name you cant connect.

This works:
mongo mongodb://pruebauser:prueba123@localhost:30001,localhost:30002,localhost:30003/prueba

And this doesnt work (you specify the replicaSet on connection ?replicaSet=rs0):

[root@localhost devcontainers-mongodb-replica-set-with-docker]# mongo mongodb://pruebauser:prueba123@localhost:30001,localhost:30002,localhost:30003/prueba?replicaSet=rs0
MongoDB shell version v4.2.0

The env file is the next below:

[root@localhost devcontainers-mongodb-replica-set-with-docker]# cat .env
