=============== MONGO CLUSTER ===========================
MongoDB cluster minimize
Config Server:
configsvr012 Shards (each a 2 member
PSS replica set): 1 Routers (mongos):
router01👉 Step 1
docker-compose up -d
👉 Step 2
docker-compose exec configsvr01 sh -c "mongosh < /scripts/init-configserver.js"
docker-compose exec shard01-a sh -c "mongosh < /scripts/init-shard01.js"
docker-compose exec shard02-a sh -c "mongosh < /scripts/init-shard02.js"
👉 Step 3
docker-compose exec router01 sh -c "mongosh < /scripts/init-router.js"
👉 Step 4
docker-compose exec router01 mongosh --port 27017
// Enable sharding for database `MyDatabase`
sh.enableSharding("MyDatabase")
// Setup shardingKey for collection `MyCollection`**
db.adminCommand( { shardCollection: "NFTDB.Post", key: { _id: "hashed"} } )
✔️ Done !!!
But before you start inserting data you should verify them first
!!! If you want to add new shard to existed cluster, check more here
📋 Verify 🔝
✅ Verify the status of the sharded cluster 🔝
docker-compose exec router01 mongosh --port 27017
sh.status()
✅ Verify status of replica set for each shard 🔝
docker exec -it shard-01-node-a bash -c "echo 'rs.status()' | mongosh --port 27017"
docker exec -it shard-02-node-a bash -c "echo 'rs.status()' | mongosh --port 27017"
✅ Check database status
docker-compose exec router01 mongosh --port 27017
use MyDatabase
db.stats()
db.MyCollection.getShardDistribution()
