Not connecting in the mongodb compass - getaddrinfo ENOTFOUND db-mongo-node17 about mongo HOT 6 CLOSED

Connecting to the replicaset works from within the network. It seems to be an issue when connecting from outside.

from mongo.

There are a few ways you could get around this problem.

1. Implement a reverse proxy using nginx or similar.
2. Add explicit ip addresses, change the ports mapping in the container and add the hosts to your hostfile,.

from mongo.

The following worked for me

compose

If you have any reference to install it with full setup with docker-compose or something, It will be very helpful on Amazon linux2, 5.0.24

from mongo.

This was on a local setup. Maybe you can use all non-default ports to avoid port in use error (27018, 27019, 27020)

from mongo.
