CV0-004 Deployment Practice Question
A DevOps team is deploying a containerized application to Google Kubernetes Engine (GKE). The team wants to automate the deployment of the application along with its dependencies, such as ConfigMaps and Services, using a single package. Which tool should the team use?
⚠ Common exam trap
CV0-004 often tests the distinction between packaging/lifecycle tools (Helm) and customization tools (Kustomize) or raw kubectl, so candidates who pick Kustomize miss that it does not provide single-package install with versioned releases.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Helm charts
Helm is the de facto package manager for Kubernetes and bundles all related manifests — Deployments, Services, ConfigMaps, Secrets, Ingress — into a single versioned chart that can be installed, upgraded, and rolled back with one command. This directly matches the requirement to deploy an application and its dependencies as a single package. Helm also supports templating and values files for environment-specific configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Helm charts
Why this is correct
Helm charts package Kubernetes manifests into one versioned, parameterised release, bundling Deployments with ConfigMaps and Services so a single `helm install` deploys the application and its dependencies together. This directly satisfies the stem's requirement for one package automating GKE deployment of the app plus its dependencies.
- ✗
kubectl apply with multiple manifest files
Why it's wrong here
Applying separate manifests with kubectl is imperative and sequential, with no single packaged, versioned release or rollback. It is tempting because it deploys ConfigMaps and Services directly, and would be correct for ad hoc changes or simple one-off resources rather than repeatable packaged deployments.
- ✗
Kustomize overlays
Why it's wrong here
Kustomize overlays patch and customise existing manifests per environment; they do not bundle an application with its ConfigMaps and Services into one installable, versioned artefact. Kustomize is the right choice when the same base manifests must be varied across dev, staging and production without duplication.
- ✗
Docker Compose
Why it's wrong here
Docker Compose orchestrates multi-container applications on a single Docker host and cannot deploy to a GKE cluster. It is tempting because it does package services and configuration into one YAML file, and would be correct for local development or a single-server deployment outside Kubernetes.
