How to build a docker replca set and connect from outside localhost

Hi fellows.

I am able to connect a non-dockerized replica set using uri = "mongodb://<host-ip-address>:27017/?replicaSet=rs0".

For this case I use a mongo.conf file that has:

net:
  port: 27017
  bindIp: 127.0.0.1,<host-ip-address>

replication:
   replSetName: "rs0"

Then, starting the replica from mongosh with rs.initiante() I get:

{
  info2: 'no configuration specified. Using a default configuration for the set',
  me: '10.18.3.101:27017',
  ok: 1,
  '$clusterTime': {
    clusterTime: Timestamp({ t: 1735656335, i: 1 }),
    signature: {
      hash: Binary.createFromBase64('AAAAAAAAAAAAAAAAAAAAAAAAAAA=', 0),
      keyId: Long('0')
    }
  },
  operationTime: Timestamp({ t: 1735656335, i: 1 })
}

Now, with de dockerized version I am trying this docker run code to get the same simple replica set configuration runing:

docker run --name mongodb -d -p 27017:27017 mongo --replSet "rs0" --bind_ip_all

Then, starting the replica from mongosh with docker exec -it mongodb mongosh --eval "rs.initiate()" I get:

{
  info2: 'no configuration specified. Using a default configuration for the set',
  me: '662dbb861df2:27017',
  ok: 1,
  '$clusterTime': {
    clusterTime: Timestamp({ t: 1735657007, i: 1 }),
    signature: {
      hash: Binary.createFromBase64('AAAAAAAAAAAAAAAAAAAAAAAAAAA=', 0),
      keyId: Long('0')
    }
  },
  operationTime: Timestamp({ t: 1735657007, i: 1 })
}

So I am not able to conect with that uri anymore.

I appreciate any help in advance!
