Setup MongoDB Replica Set with Docker

1. Start MongoDB containers:

   docker compose up -d --build

2. Initialize the Replica Set:

   docker exec -it mongo1 mongosh

3. Inside the Mongo shell, run:

   rs.initiate({
     _id: "my-mongo-set",
     members: [
       { _id: 0, host: "mongo1:27017" },
       { _id: 1, host: "mongo2:27017" },
       { _id: 2, host: "mongo3:27017" }
     ]
   })

4. Check the replica set status:

   rs.status()

   Ensure there is a PRIMARY and two SECONDARY.
