MongoDB Store Configuration

View as Markdown

Overview

The MongoDB Store module provides persistent storage for health events collected by NVSentinel monitors. It deploys a MongoDB replica set with TLS encryption and authentication. This document covers all Helm configuration options for system administrators.

Configuration Reference

Module Enable/Disable

Controls whether the mongodb-store module is deployed in the cluster.

1global:
2  mongodbStore:
3    enabled: true

Note: Several modules (fault-quarantine, node-drainer, fault-remediation, event-exporter) depend on the datastore. Enable the datastore when using these modules.

Note: cert-manager must be installed in the cluster before deploying mongodb-store.

Initialization Job Placement

Configures node placement for initialization jobs.

1mongodb-store:
2  job:
3    nodeSelector: {}
4    tolerations: []

Parameters

nodeSelector

Node selector for scheduling MongoDB initialization jobs.

tolerations

Tolerations for MongoDB initialization jobs to run on tainted nodes.

Node Placement

Controls pod scheduling for MongoDB replicas.

1mongodb-store:
2  mongodb:
3    nodeSelector: {}
4    tolerations: []

Parameters

nodeSelector

Node selector for scheduling MongoDB replica pods.

tolerations

Tolerations for MongoDB pods to run on tainted nodes.

Metrics Exporter

Configures MongoDB metrics exporter for monitoring integration.

1mongodb-store:
2  mongodb:
3    metrics:
4      enabled: true
5      image:
6        registry: docker.io
7        repository: bitnamilegacy/mongodb-exporter
8        tag: 0.41.2-debian-12-r1

Parameters

enabled

Enable MongoDB metrics exporter sidecar container.

image.repository

Container image for the MongoDB exporter.

image.tag

Image tag for the MongoDB exporter.

The exporter exposes metrics on port 9216 for Prometheus scraping.

Helper Images

Container images used in init containers and sidecars.

1mongodb-store:
2  mongodb:
3    helperImages:
4      kubectl:
5        repository: docker.io/bitnamilegacy/kubectl
6        tag: "1.30.6"
7        pullPolicy: IfNotPresent
8      mongosh:
9        repository: ghcr.io/rtsp/docker-mongosh
10        tag: "2.5.2"
11        pullPolicy: IfNotPresent

Parameters

kubectl

Image for Kubernetes operations in init containers (secret creation, certificate management).

mongosh

Image for MongoDB shell operations and database initialization.
