👉 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: "3.7"
services:
mongodb:
image: mongo:6.0.2
container_name: mongoDB
environment: # Not working without username and pass. So keep it.
- MONGO_INITDB_ROOT_USERNAME=your_username # username
- MONGO_INITDB_ROOT_PASSWORD=aKXVLF7CZFNNvzWRZbun # password
- MONGO_REPLICA_SET_NAME=rs0
volumes:
- ~/docker-data/mongo-db/data:/data/db
- ./:/opt/keyfile/
ports:
- 27017:27017 # Suggestion: Do not use different port
entrypoint:
- bash
- -c
- |
chmod 400 /opt/keyfile/keyfile
chown 999:999 /opt/keyfile/keyfile
exec docker-entrypoint.sh $$@
command: "mongod --bind_ip_all --keyFile /opt/keyfile/keyfile --replSet rs0"
2.) Generate keyfile
- Create keyfile in same directory using below commands.
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.
3.) Start docker container
docker compose up -d
4.) Connect terminal in container
# List all containers
docker container ls
#fill CONTAINER_ID from above command
docker exec -it CONTAINER_ID /bin/bash
5.) Connect to mongodb
mongosh -u your_username -p aKXVLF7CZFNNvzWRZbun
6.) Start replica set
rs.initiate({
_id : "rs0",
members: [
{ _id: 0, host: "127.0.0.1:27017" }
]
});
7.) Give full permissions to user
db.getSiblingDB("admin").updateUser(
"your_username",
{
customData: {},
roles: [
{ "role": "root", "db": "admin" },
{ "role": "readAnyDatabase", "db": "admin" },
{ "role": "readWriteAnyDatabase", "db": "admin" },
{ "role": "userAdminAnyDatabase", "db": "admin" },
{ "role": "dbAdminAnyDatabase", "db": "admin" },
{ "role": "backup", "db": "admin" },
{ "role": "restore", "db": "admin" },
{ "role": "clusterAdmin", "db": "admin" },
{ "role": "clusterManager", "db": "admin" },
{ "role": "clusterMonitor", "db": "admin" },
{ "role": "hostManager", "db": "admin" },
{ "role": "dbAdmin", "db": "admin" },
{ "role": "dbOwner", "db": "admin" },
{ "role": "userAdmin", "db": "admin" },
],
}
);
8.) Connection string sample to connect to above
- We can use MongoDB compass, NoSQLBooster, Navicat or Studio3T to connect to database.
mongodb://your_username:aKXVLF7CZFNNvzWRZbun@127.0.0.1:27017/your_database_name?authSource=admin&replicaSet=rs0&directConnection=true
