Deploying MongoDB in kubernetes does not create pods/services

Question

I'm following this https://github.com/mongodb/mongodb-enterprise-kubernetes and https://docs.opsmanager.mongodb.com/current/tutorial/install-k8s-operator/ to deploy mongodb inside a Kubernetes cluster on DigitalOcean.

So far everything worked except the last step. Deploying mongodb. I'm trying to do like suggested in the documentation:

---
apiVersion: mongodb.com/v1
kind: MongoDbReplicaSet
metadata:
  name: mongodb-rs
  namespace: mongodb
spec:
  members: 3
  version: 4.0.4

  persistent: true

  project: project-0
  credentials: mongodb-do-ops

It doesn't work. The resource of type MongoDbReplicaSet is created, but no pods and services are deployed like written in docs.

kubectl --kubeconfig="iniside-k8s-test-kubeconfig.yaml" describe MongoDbReplicaSet mongodb-rs -n mongodb

Name:         mongodb-rs

Answer 1

I got it working. As It stands in documentation here: https://docs.opsmanager.mongodb.com/current/tutorial/install-k8s-operator/

data.projectName

Is not optional. After looking at operator logs, operator cloudn't create replica set deployment because projectName was missing in ConfigMap.
