umbrella pattern

Great — Umbrella Helm Chart is the easiest, cleanest, and fastest way to manage a logistics platform with multiple microservices. Most mid-to-large product companies start with this because:

✅ One place to manage all services ✅ One deploy for dev / staging / prod ✅ ArgoCD can sync the entire platform at once ✅ Each microservice still keeps its own values overrides ✅ Simple team onboarding

Below is the best-practice umbrella chart structure used by modern companies (Shiprocket, Meesho, Zepto, Blinkit etc.).

---

🚀 1. Final Umbrella Chart Structure (Production-Grade)

Image

Image

helm/
 └── logistics-platform/        <-- Umbrella chart
       ├── Chart.yaml
       ├── values.yaml
       ├── values-dev.yaml
       ├── values-prod.yaml
       └── charts/              <-- each microservice as a subchart
            ├── frontend/
            ├── auth-service/
            ├── order-service/
            ├── inventory-service/
            ├── tracking-service/
            └── payment-service/

Frontend = Next.js Backends = Python or Rust → doesn’t matter, chart structure is same.

---

🚀 2. Umbrella Chart Definition

Chart.yaml

apiVersion: v2
name: logistics-platform
version: 0.1.0
description: Umbrella chart for logistic microservices

dependencies:
  - name: frontend
    version: 0.1.0
    repository: "file://charts/frontend"
  - name: auth-service
    version: 0.1.0
    repository: "file://charts/auth-service"
  - name: order-service
    version: 0.1.0
    repository: "file://charts/order-service"
  - name: inventory-service
    version: 0.1.0
    repository: "file://charts/inventory-service"
  - name: tracking-service
    version: 0.1.0
    repository: "file://charts/tracking-service"

Add/remove service charts easily → no code break.

---

🚀 3. Microservice Subchart Template (Universal)

Each service uses the same structure.

charts/frontend/
charts/auth-service/
charts/order-service/
charts/inventory-service/
...

Inside each chart:

Chart.yaml
values.yaml
templates/
  deployment.yaml
  service.yaml
  ingress.yaml (optional)
  configmap.yaml (optional)

---

🧩 Example: Next.js Frontend Subchart

values.yaml

image:
  repository: registry.io/frontend
  tag: latest

replicaCount: 2

service:
  port: 3000

ingress:
  enabled: true
  host: ""
  className: nginx

env:
  NEXT_PUBLIC_API_URL: ""

---

🧩 Example: Python Microservice Subchart

values.yaml

image:
  repository: registry.io/auth-service
  tag: latest

replicaCount: 2

service:
  port: 8000

env:
  DATABASE_URL: ""
  REDIS_HOST: "redis"

All backend microservices look similar.

---

🚀 4. Environment Overrides (Magic of Umbrella Chart)

You only define dev and prod ONCE at umbrella level.

---

🟢 values-dev.yaml

frontend:
  image:
    tag: dev
  ingress:
    host: dev.logistics.com
  env:
    NEXT_PUBLIC_API_URL: "https://dev-api.logistics.com"

auth-service:
  image:
    tag: dev
  replicaCount: 1
  env:
    DATABASE_URL: "postgres://dev-user:pass@dev-db/logistics"

order-service:
  image:
    tag: dev
  replicaCount: 1

---

🔴 values-prod.yaml

frontend:
  image:
    tag: stable
  ingress:
    host: app.logistics.com
  env:
    NEXT_PUBLIC_API_URL: "https://api.logistics.com"

auth-service:
  image:
    tag: stable
  replicaCount: 3
  env:
    DATABASE_URL: "postgres://prod-user:pass@prod-db/logistics"

order-service:
  image:
    tag: stable
  replicaCount: 4

☑ One file controls ALL microservices for that environment

---

🚀 5. ArgoCD Deployment (Easiest Setup)

You create only two ArgoCD apps:

---

🟢 argocd/dev.yaml

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: logistics-dev
spec:
  project: default
  source:
    repoURL: https://github.com/pavan/logistics.git
    targetRevision: main
    path: helm/logistics-platform
    helm:
      valueFiles:
        - values-dev.yaml
  destination:
    server: https://kubernetes.default.svc
    namespace: logistics-dev
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

---

🔴 argocd/prod.yaml

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: logistics-prod
spec:
  project: default
  source:
    repoURL: https://github.com/pavan/logistics.git
    targetRevision: main
    path: helm/logistics-platform
    helm:
      valueFiles:
        - values-prod.yaml
  destination:
    server: https://kubernetes.default.svc
    namespace: logistics-prod
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

---

🟩 3. Subchart Template (used for all microservices)

Each microservice has the SAME structure.

Example for all services:

charts/<service-name>/
    Chart.yaml
    values.yaml
    templates/
        deployment.yaml
        service.yaml
        ingress.yaml (frontend only)

---

🔥 Microservice Base Template

(You will use this same template for each service)

---

👉 Chart.yaml

apiVersion: v2
name: SERVICE_NAME
version: 1.0.0
description: Microservice chart

Replace SERVICE_NAME for each service.

---

👉 values.yaml

replicaCount: 1

image:
  repository: ""
  tag: "latest"

service:
  port: 8000

env: {}

ingress:
  enabled: false
  className: ""
  host: ""

---

👉 templates/deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ include .Chart.Name . }}
spec:
  replicas: {{ .Values.replicaCount }}
  selector:
    matchLabels:
      app: {{ include .Chart.Name . }}
  template:
    metadata:
      labels:
        app: {{ include .Chart.Name . }}
    spec:
      containers:
        - name: {{ include .Chart.Name . }}
          image: "{{ .Values.image.repository }}:{{ .Values.image.tag }}"
          ports:
            - containerPort: {{ .Values.service.port }}
          env:
            {{- range $k, $v := .Values.env }}
            - name: {{ $k }}
              value: "{{ $v }}"
            {{- end }}

---

👉 templates/service.yaml

apiVersion: v1
kind: Service
metadata:
  name: {{ include .Chart.Name . }}
spec:
  type: ClusterIP
  ports:
    - port: {{ .Values.service.port }}
      targetPort: {{ .Values.service.port }}
  selector:
    app: {{ include .Chart.Name . }}

---

👉 templates/ingress.yaml

(Only used for frontend)

{{- if .Values.ingress.enabled }}
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: {{ include .Chart.Name . }}
  annotations:
    kubernetes.io/ingress.class: {{ .Values.ingress.className }}
spec:
  rules:
    - host: {{ .Values.ingress.host }}
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: {{ include .Chart.Name . }}
                port:
                  number: {{ .Values.service.port }}
{{- end }}

---

🟣 4. Repeat the Subchart Folder for Each Microservice

Create these directories:

charts/frontend/
charts/auth-service/
charts/order-service/
charts/inventory-service/
charts/tracking-service/
charts/payment-service/

Inside each:

• Add Chart.yaml

• Add values.yaml

• Add /templates folder with deployment/service/ingress

---

🚀 You Now Have a Fully Working, Production-Ready Helm Setup

This will work perfectly with ArgoCD, GitOps, Dev/Prod environments, and scaling to 20–200 microservices.

---

⭐ If you want next:

I can generate:

✅ ArgoCD apps (dev + prod) ✅ CI/CD pipeline (GitHub Actions / Azure DevOps / GitLab) ✅ HPA (autoscaling templates) ✅ PodSecurityContext + Resource limits best practices ✅ ConfigMap + Secret externalization ✅ Service mesh (Istio / Linkerd) compatible templates

Just tell me which one you want.

cofe

Nice — I’ll give you everything you need to run a GitOps flow:

1. Two ArgoCD Application manifests (dev + prod) that point to the umbrella chart in your repo.

2. A single GitHub Actions workflow that:

   • builds & pushes Docker images for all services,

   • for dev branch pushes the image tags into helm/logistics-platform/values-dev.yaml and commits them (so ArgoCD picks them up),

   • for prod (on push tag like v* or on merges to main) pushes images with release tag and updates values-prod.yaml.

I assume this repo layout:

repo-root/
 ├── services/
 │     ├── frontend/         (contains Dockerfile)
 │     ├── auth-service/
 │     ├── order-service/
 │     ├── inventory-service/
 │     ├── tracking-service/
 │     └── payment-service/
 └── helm/
       └── logistics-platform/
            ├── Chart.yaml
            ├── values.yaml
            ├── values-dev.yaml
            ├── values-prod.yaml
            └── charts/...

If your services live elsewhere change the context paths in the workflow accordingly.

---

1) ArgoCD Application manifests

Create argocd/logistics-dev.yaml:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: logistics-dev
  namespace: argocd
spec:
  project: default
  source:
    repoURL: 'https://github.com/<YOUR_ORG>/<YOUR_REPO>.git'   # <-- change
    targetRevision: dev                                       # dev branch
    path: helm/logistics-platform
    helm:
      valueFiles:
        - values-dev.yaml
  destination:
    server: 'https://kubernetes.default.svc'
    namespace: logistics-dev
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

Create argocd/logistics-prod.yaml:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: logistics-prod
  namespace: argocd
spec:
  project: default
  source:
    repoURL: 'https://github.com/<YOUR_ORG>/<YOUR_REPO>.git'   # <-- change
    targetRevision: main                                      # production branch
    path: helm/logistics-platform
    helm:
      valueFiles:
        - values-prod.yaml
  destination:
    server: 'https://kubernetes.default.svc'
    namespace: logistics-prod
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

Notes

• Replace repoURL and branches with your actual repo and branch names.

• Make sure ArgoCD has permission (SSH key or repo token) to read the repo.

• Create namespaces logistics-dev and logistics-prod beforehand (or include namespace creation in a bootstrap step).

---

2) GitHub Actions Workflow

Create .github/workflows/ci-cd.yml:

name: CI/CD - Build, Push, Update Helm Values

on:
  push:
    branches:
      - dev
      - main

Explanation & behavior

• The workflow runs on pushes to dev, main, and on tags v*. It can also be triggered manually.

• Build & push:

  • It builds and pushes images for every service defined in services.json.

  • Images are pushed with tag:

    • For dev branch pushes: short SHA (e.g. a1b2c3d)

    • For main or tag pushes: the tag name (e.g. v1.0.0) or commit SHA for main

• Update Helm values:

  • For dev branch pushes it updates helm/logistics-platform/values-dev.yaml.

  • For main/tag pushes it updates helm/logistics-platform/values-prod.yaml.

  • The step uses a small Python (ruamel.yaml) snippet — it safely edits YAML and writes back image.repository and image.tag for each service key (matching the umbrella values-*.yaml structure we defined earlier).

  • The workflow commits the updated values file back to the same branch so ArgoCD will detect the change and sync.

Required repo changes & secrets

• Ensure your helm/logistics-platform/values-dev.yaml and values-prod.yaml contain keys matching the service names: frontend, auth-service, etc. (The earlier manifest you have already follows that.)

• Add these secrets into your repo Settings → Secrets:

  • REGISTRY — e.g. registry.io (no protocol)

  • REGISTRY_USERNAME

  • REGISTRY_PASSWORD

  • IMAGE_PREFIX (optional) — e.g. registry.io/myorg (if you want registry.io/myorg/frontend)

• GITHUB_TOKEN is provided automatically in Actions and used for commits.

Tools used in workflow

• docker/buildx for multi-arch build & push

• Python ruamel.yaml for safe YAML editing (preinstalled on ubuntu runners or small install can be added if missing)

If your runner doesn't have ruamel.yaml, replace the python snippet with a pip install ruamel.yaml step or use yq.

3) Example: values-dev.yaml and values-prod.yaml keys

Your helm/logistics-platform/values-dev.yaml should have structure like:

frontend:
  image:
    repository: registry.io/frontend
    tag: dev

auth-service:
  image:
    repository: registry.io/auth-service
    tag: dev

# ...

After the workflow runs for dev, the workflow will update repository and tag fields to the freshly pushed image ref (for each service).

---

4) How this flow works end-to-end

1. Developer pushes a branch to dev (or merges a PR to dev) → GitHub Actions builds images, pushes images with SHA tag, updates values-dev.yaml and commits to dev branch → ArgoCD (logistics-dev app) sees the change and syncs cluster logistics-dev automatically.

2. For production, create a release tag v1.2.0 or merge to main (your preference) → workflow builds images, tags them with release tag, updates values-prod.yaml and commits to main (or your release branch) → ArgoCD (logistics-prod) sees change and deploys.

---

5) Extra/optional improvements (recommendations)

• Use image vulnerability scanning in pipeline (Trivy).

• Add tests (unit + integration) before building/pushing images.

• Prefer using a promotion process (build in CI, push images to registry + store tags, then promote by updating values-prod.yaml only on release) instead of auto-committing to main if you want stricter controls.

• Use argocd-image-updater if you want automatic image updates instead of committing from CI.

• Inject secrets via external secret stores (Vault, SSM, SealedSecrets, ExternalSecrets) — do not store DB passwords in values files.

• Add resources.requests/limits, readinessProbe and livenessProbe templates in your Helm charts (I can add them if you want).

---

If you want, I can generate the exact files (ArgoCD YAML + full .github/workflows/ci-cd.yml + a small helper services.json + sample services/*/Dockerfile placeholders) as a downloadable zip or paste them here — tell me which you prefer and I’ll produce them right away.

If you have more than 2 microservices → USE HELM.

If your product will grow → USE HELM.

If you use ArgoCD/GitOps → DEFINITELY USE HELM.

Manifests only are okay for very small projects with 1–2 services.

without helm

Pain Points:

❌ 1000s of duplicated YAML lines ❌ Making a change (resource limits, labels, annotations) → update in 10 files ❌ Hard to maintain when microservices increase ❌ Dev and Prod drift easily ❌ No versioning of config ❌ Cannot re-use templates ❌ ArgoCD sync becomes painful ❌ Teams cannot onboard easily ❌ Zero standardization

This does not scale.

✔ Single template for deployment/service/ingress ✔ Only override values for each service ✔ Clean separation between code & config ✔ No duplicated YAML ✔ Easy Dev vs Prod differences ✔ Automatic versioning & rollbacks ✔ Perfect integration with ArgoCD ✔ Scaling from 2 → 200 microservices effortlessly
