I can run everything perfectly but I can not connect to the set by any client.

i have same problem
hel;p

Error:
getaddrinfo ENOTFOUND mongodb-primary

If that helps, bitnami/mongodb is a super good image.

  mongodb:
    image: bitnami/mongodb
    environment:
      MONGODB_REPLICA_SET_MODE: primary
      ALLOW_EMPTY_PASSWORD: "yes"

How did you configure the port

I have setup everything in this https://github.com/nguyenduyhust/docker-mongodb-replica-set.
Great if that's what you're looking for.

When I tried to connect with string URI mongodb://localhost:27011,localhost:27012,localhost:27013/?replicaSet=rs0 using Compass I got the following error
getaddrinfo EAI_AGAIN mongo1

By the way, you all would have to expose all Mongo replicaset instances ports in order to get connected to them, so I think It's redundant being exposing ports, It's better to use host network mode.

I was looking for a simple Compose for this and, unfortunately, I didn't find one complete and simple at the same time, because of that I made one as simple as possible where the secondary ones ingress their selfies on the master without any third-party script.

I hope you all find it useful

docker exec -it mongodb /bin/bash

This worked perfectly for me to create and start the mongodb set on docker containers. I can also connect to any of the servers using compass. But when I tried to open a connection from another server in the docker network (a php server), using php mongodb client, I got "Authentication failed" using this url:

mongodb://172.24.0.5:27017,172.24.0.3:27017,172.24.0.4:27017?replicaSet=dbrs

I am also sending my username and password, same that I am using in the compass connection url. The internal ips are correct, so that is not the problem.

So, basically, replicaset is up and running, I can connect from MongoDB Compass but I can't connect from my PHP code from a docker container in the same docker network.
