Unable to connect to replica set running within Docker container

system: Linux / Docker

package: mongo-memory-server

What is your question?

When creating the 1 node replica set with the node application I can connect properly. I have dockerized it and, it spins up the container, but my MongoDB Client (Robo 3T) is unable to connect. It times out

I have configured it to bing all IP addresses

import { MongoMemoryReplSet } from "mongodb-memory-server";

// This will create an new instance of "MongoMemoryReplSet" and automatically start all Servers
const replset = await MongoMemoryReplSet.create({
  instanceOpts: [
    {
      port: 27017,
      ip: `::,0.0.0.0`,
      storageEngine: "wiredTiger"
    }
    // each entry will result in a MongoMemoryServer (replSet.count will not count towards here)
  ],
  replSet: {
    name: "rs",
    count: 1,
    storageEngine: "wiredTiger" // by default was ephermeralForTest
  }
});

console.log("Replica set is running...");
const uri = replset.getUri();
console.log(`Connect using: ${uri}`);

// The ReplSet can be stopped again with
//await replset.stop();

// Listen for termination signals
process.on("SIGINT", gracefulShutdown);
process.on("SIGTERM", gracefulShutdown);

function gracefulShutdown() {
  console.log("\nReceived shutdown signal. Stopping replica set...");
  replset.stop().then(() => {
    console.log("Replica set stopped. Exiting...");
    process.exit(0);
  });
}

But, for some reason, from my OS (Windows) I can sping up the docker container, I can see that the MongoDB is running inside properly but I can't connect from outside.

It can be reproduced here at this public repository: https://gitlab.com/sunnyatticsoftware/mongodb-rs/-/tree/8740a5146ad19bb8a1386f2ed2d883c6a20818cc

Spin up the docker container with this

docker run --name mongodbrs -p 27017:27017 registry.gitlab.com/sunnyatticsoftware/mongodb-rs

And the MongoDB replicaset will run with connection string mongodb://127.0.0.1:27017/?replicaSet=rs

Timed out after 30000 ms while waiting for a server that matches com.mongodb.client.internal.MongoClientDelegate$1@5ffb8bd6. Client view of cluster state is {type=REPLICA_SET, servers=[{address=127.0.0.1:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketReadException: Prematurely reached end of stream}}]

Inside the container, I can see mongo is up and running, as I can install mongosh and do the following

# mongosh --host localhost --port 27017
Current Mongosh Log ID: 652ea8f840f790f5d361ca6d

I can also check the status

Any help would be appreciated.
