I’m trying to setup a MongoDB ReplicaSet with Helm Chart. I added the following dependency in my Chart.yaml file:

dependencies:
  - name: mongodb
    version: "15.3.1"
    repository: "https://charts.bitnami.com/bitnami"

And my values.yaml file has this configuration:

mongodb:
  architecture: replicaset
  replicaCount: 3
  externalAccess:
    enabled: true
    service:
      type: LoadBalancer
    autoDiscovery:
      enabled: true
  serviceAccount:
    create: true
  automountServiceAccountToken: true
  rbac:
    create: true
  auth:
    enabled: false
  initdbScripts:
    setup_replicaset_script.js : |
      rs.add("test-mongodb-0-external.default.svc.cluster.local:27017")
      rs.add("test-mongodb-1-external.default.svc.cluster.local:27017")
      rs.add("test-mongodb-2-external.default.svc.cluster.local:27017")

However, when I do:

helm dependency update test1 
helm dependency build test1
helm install test test1

I found two issues:

The first issue is that I’m getting 3 services, which is correct as per my configuration:

kubectl get svc                    
NAME                            TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)           AGE
kubernetes                      ClusterIP      10.96.0.1        <none>        443/TCP           8m52s
test-mongodb-0-external         LoadBalancer   10.107.131.138   127.0.0.1     27017:32498/TCP   8m23s
test-mongodb-1-external         LoadBalancer   10.110.127.112   127.0.0.1     27017:32345/TCP   8m23s
test-mongodb-2-external         LoadBalancer   10.109.4.225     127.0.0.1     27017:31756/TCP   8m23s
test-mongodb-arbiter-headless   ClusterIP      None             <none>        27017/TCP         8m23s
test-mongodb-headless           ClusterIP      None             <none>        27017/TCP         8m23s

But I’m only getting 2 pods (test-mongodb-2 seems to be missing for some reason)

k8s kubectl get po                                        
NAME                                     READY   STATUS             RESTARTS      AGE
test-mongodb-0                           1/1     Running            0             16m
test-mongodb-1                           0/1     Running            0             16m
test-mongodb-arbiter-0                   1/1     Running            1 (15m ago)   16m

And the second issue is that the ReplicaSet gets initialized on test-mongodb-0 but not in test-mongodb-1

I tried many of the more recent versions of the chart and the issue still persists. I’m not sure if I’m missing some configuration.
