Accessing the same mongoDB instance from multiple Docker containers

I have two containers (A and B) running Node + MongoDB. A contains restricted endpoints that require a valid token in order to read + write from the database. B will contain public endpoints that have no request requirements and allow anyone to read certain documents from the database.

The endpoints exposed in both A and B should interact with the same database. I'm not sure how to do this when it comes to MongoDB.

I'm defining the schema / model for the collection in container A, like so:

const mongoose = require('mongoose');
const Project = new mongoose.Schema({ ... });

From container B, all I want to do is to be able to sift through all Projects in the database. I don't think I'm supposed to create the same schema in this new container.

It's important to note that container B is successfully connected to the same DB as container A. It's just a matter of sifting through it via mongoose.

TL;DR: How can I access container A's db from container B, where I haven't registered any models? I'm pretty new to this so any info would be helpful.

you can use docker-compose.yml like

mongodb:
 image: mongo
dockera:
 links:
   - mongodb:mongodb
dockerb:
 links:
   - mongodb:mongodb

then you containera and containerb will connect the same mongodb
