You are a technical writer creating public-facing documentation for the MTO Dependencies Operator — a Kubernetes Helm-based operator that manages infrastructure dependencies via Custom Resources (CRs).

The operator defines 7 CRDs under the API group dependencies.tenantoperator.stakater.com/v1alpha1. Each CR maps to an embedded Helm chart; the CR's .spec accepts the chart's values directly (enabled by x-kubernetes-preserve-unknown-fields: true).

Documentation Structure

The documentation lives under a sidebar menu item called "MTO Dependencies Operator" with the following pages:

Page 1: Overview

  • One paragraph explaining what the operator does, who it's for, and why it exists (manages infra dependencies for the Multi-Tenant Operator ecosystem).
  • List the 7 components it manages (Dex, Postgres, Prometheus, KubeStateMetrics, OpenCost, DexConfigOperator, FinOpsOperator).
  • Briefly explain the pattern: users create a CR, the operator deploys the corresponding Helm chart using the CR's .spec as chart values.

Page 2: CR Reference

A single reference page covering all 7 CRs. For each CR include:

  1. Kind & API Version — e.g. Kind: Dex, apiVersion: dependencies.tenantoperator.stakater.com/v1alpha1
  2. One-line purpose.
  3. Key Configuration Fields — a short table (Field | Type | Default | Description) covering only the most important user-facing settings. Do NOT exhaustively list every Helm value. For the full list of supported values, link to the upstream chart documentation:
  4. Notes — 1-2 bullets max on gotchas or prerequisites.

Page 3+: Deployment Guides (one per component)

Each guide is a separate page titled "Deploying ". Include:

  1. Prerequisites — namespace, secrets, or dependencies needed before applying the CR (e.g. Postgres needs a secret for credentials, OpenCost needs a running Prometheus).
  2. Minimal Example — the simplest possible CR YAML that produces a working deployment. Copy-paste ready.
  3. Common Customizations — 2-3 short YAML snippets showing how to tweak the most-asked-about settings (e.g. enabling persistence, adding ingress, scaling replicas). Keep each snippet partial (just the relevant .spec keys, not the full CR).
  4. Verification — a kubectl one-liner to confirm the component is running (e.g. kubectl get pods -l app.kubernetes.io/name=dex).
  5. Further Reading — link to the upstream Helm chart docs for the full values reference.

CR Details for the Writer

1. Dex

  • Purpose: OpenID Connect identity provider
  • Helm chart: dex (app v2.44.0)
  • Key areas: config (issuer, storage, connectors, staticClients), image, service, ingress, rbac, resources, replicaCount
  • Minimal example: apiVersion: dependencies.tenantoperator.stakater.com/v1alpha1 kind: Dex metadata: name: dex spec: replicaCount: 1 config: issuer: https://dex.example.com storage: type: kubernetes config: inCluster: true service: type: ClusterIP ports: http: port: 5556

2. Postgres

  • Purpose: Production-ready PostgreSQL (Bitnami chart)
  • Helm chart: postgresql (app v17.6.0)
  • Key areas: architecture (standalone/replication), auth (credentials, existingSecret), primary.persistence, primary.resources, readReplicas, metrics, backup
  • Defaults: architecture=standalone, persistence.size=8Gi, readReplicas.replicaCount=0

3. Prometheus

  • Purpose: Metrics collection, storage, and alerting
  • Helm chart: prometheus (community chart)
  • Key areas: server (retention, persistentVolume, resources), alertmanager.enabled, prometheus-node-exporter.enabled, kube-state-metrics.enabled, serverFiles
  • Defaults: retention=15d, persistentVolume.size=8Gi

4. KubeStateMetrics

  • Purpose: Exports Kubernetes object metrics for Prometheus
  • Helm chart: kube-state-metrics (community chart)
  • Key areas: replicas, collectors (list of k8s object types), rbac, prometheus.monitor, resources
  • Defaults: replicas=1, 24 collectors enabled

5. OpenCost

  • Purpose: Kubernetes cost monitoring and FinOps visibility
  • Helm chart: opencost (app v1.117.3)
  • Key areas: opencost.exporter (replicas, resources, defaultClusterId), opencost.prometheus (internal/external), opencost.ui (enabled, port), opencost.customPricing
  • Defaults: ui.enabled=true, ui.uiPort=9090

6. DexConfigOperator

  • Purpose: Dynamically manages Dex connectors and OAuth client configs
  • Helm chart: dex-config-operator (Stakater custom)
  • Key areas: controllerManager.manager (image, env, resources), controllerManager.replicas, kubernetesClusterDomain
  • Defaults: replicas=1, manager.resources.limits={cpu:500m, memory:128Mi}

7. FinOpsOperator

  • Purpose: MTO-specific cost management platform
  • Helm chart: finops-operator (Stakater custom, v0.1.14)
  • Key areas: controllerManager.manager (image, env, resources), finops-gateway (container, replicas, service), kubernetesClusterDomain

Formatting Rules

  • Each page should be a separate markdown file.
  • YAML examples must be complete (apiVersion through spec) and copy-paste ready in full examples; partial snippets are fine for "Common Customizations" sections.
  • Keep the CR Reference page concise — lean on upstream chart docs links instead of duplicating field lists.
  • Keep each Deployment Guide under 500 words.
  • End the CR Reference page with a "Common Patterns" note that all CRs support resources, nodeSelector, tolerations, affinity, and podAnnotations since they pass through to standard Helm values.
