replicaset_cluster

Creating a replicaset cluster on mongodb

1. Create .env file and store on it

MONGO_UN=your_root_un
MONGO_PW=your_root_complicated_password

2. run the compose file

docker-compose up --build

3. get into the one of your nodes and initiate the cluster

3.1. Get into the container

docker exec -it mongo-primary bash

3.2. Connect to the mongodb running instance

mongosh -u your_root_un -p your_root_complicated_password

3.3 Initiate the replicaset

rs.initiate({"_id" : "bosta-rs-1","members" : [{"_id" : 0,"host" : "mongo-primary:27017"},{"_id" : 1,"host" : "mongo-worker-1:27017"},{"_id" : 2,"host" : "mongo-worker-2:27017"}]});

4. Exit from mongosh then reconnect to the whole cluster

mongosh mongodb://your_root_un:your_root_complicated_password@mongo-primary,mongo-worker-1:27018,mongo-worker-2:27019/?replicaSet=bosta-rs-1

The above replicaset URI use it when you connect using any other client such as nodejs
