MongoDB - 6, Start database with single replica

👉 We can use MongoDB transactions feature only when MongoDB started in replica mode or we can say cluster mode.

👉 Moreover 🚀API Maker needs MongoDB 6 to be running in replica mode.

So, to start MongoDB in replica mode follow below steps.

1.) Create docker-compose.yml file with below text

Create some directory and stay in that directory and run all below commands.

version: "3.8"
services:
    am_mongodb:
        image: mongo:6.0.23
        container_name: api_maker_mongodb_rs
        command: [ "--replSet", "rs0", "--bind_ip_all", "--port", "27017", "--keyFile", "/opt/keyfile" ]
        ports:
            - 27017:27017 # For separate port you can keep 27018:27017
        environment: # Not working without username and pass. So keep it.
            - MONGO_INITDB_ROOT_USERNAME=api_maker_user # username
            - MONGO_INITDB_ROOT_PASSWORD=aKXVLF7CZFNNvzWRZbdd # password
            - MONGO_REPLICA_SET_NAME=rs0
        healthcheck:
            test: echo "try { rs.status() } catch (err) { rs.initiate({_id:'rs0',members:[{_id:0,host:'127.0.0.1:27017'}]}) }" | mongosh -u "api_maker_user" -p "aKXVLF7CZFNNvzWRZbdd" --port 27017 --quiet
            interval: 5s
            timeout: 30s
            start_period: 0s
            retries: 30
        volumes:
            - ./docker-data/am_mongodb/db:/data/db
            - ./docker-data/am_mongodb/configdb:/data/configdb
            - ./keyfile:/opt/keyfile

2.) Generate keyfile or use below

Create keyfile in same directory using below commands or create file from below keyfile content.

MacOS

openssl rand -base64 741 > keyfile
chmod 600 keyfile

Linux

openssl rand -base64 756 > keyfile
chmod 600 keyfile
sudo chown 999 keyfile
sudo chgrp 999 keyfile

Windows

We can use linux commands in git bash for that.

Keyfile content

3.) Start docker container

docker-compose up -d
# Or with specific file
/usr/bin/docker-compose --project-name api_maker -f ~/config/docker-compose.yml up -d

# Stop docker container
/usr/bin/docker-compose --project-name api_maker -f ~/config/docker-compose.yml up -d

4.) Connection string sample to connect to above

We can use MongoDB compass, NoSQLBooster, Navicat or Studio3T to connect to database.

In case of not working, try removing directConnection query parameter.

mongodb://api_maker_user:aKXVLF7CZFNNvzWRZbdd@127.0.0.1:27017?authSource=admin&replicaSet=rs0&directConnection=true
