For most teams, a practical sequence is helm lint, render with helm template, validate and scan those manifests, run helm test in a cluster, then package and publish the chart.
Which Helm chart tools should you use?
There is no single tool that checks every chart concern. Helm handles chart authoring and release operations; other tools inspect rendered Kubernetes YAML, enforce organization-specific policies, or coordinate multiple releases. Choose tools for the checks you need rather than treating any one linter or scanner as a complete quality or security review.
| Job | Useful tools | What they examine or do |
|---|---|---|
| Author and manage releases | Helm CLI and its commands | Chart structure, rendering, packaging, dependencies, installation, testing, and release operations |
| Find and distribute charts | Artifact Hub, chart repositories, OCI registries, ORAS | Chart discovery and chart or repository-metadata distribution |
| Coordinate releases and chart CI | Helmfile, chart-testing (ct), helm-unittest |
Multi-release management, changed-chart checks, and template assertions |
| Validate and assess rendered resources | kubeconform, KubeLinter, policy and security analyzers | Kubernetes schemas, configuration practices, and security or organization rules |
What does Helm provide on its own?
Helm is the baseline chart package manager and release client. Its commands cover much of the lifecycle, but they answer different questions: helm lint checks chart-level issues, while helm template shows the Kubernetes manifests produced from a chart and values. Neither replaces Kubernetes schema validation, policy checks, or testing an installed release.
Authoring, rendering, and packaging
helm create: Scaffold a chart to start authoring with Helm conventions.helm lint: Run fast chart-level checks before rendering or publishing. Treat warnings and failures as prompts to review the chart, not as proof that the rendered resources are safe.helm template: Render templates locally using the values you specify. Use the resulting YAML for review and downstream schema, policy, and security tools.helm dependency: Update or build chart dependencies. Review dependency choices and versions as part of chart maintenance.helm package: Build a chart archive for distribution. If your process requires supply-chain verification, pair packaging with provenance material and verification.
Release operations and chart tests
Helm also installs and upgrades releases, reports status and history, runs chart tests, rolls back revisions, and uninstalls releases. A chart test is a Kubernetes resource marked with a Helm test hook annotation; run it against an installed release with helm test RELEASE_NAME. Tests must complete successfully to pass. Use an ephemeral or staging cluster when you need to exercise real cluster behavior rather than only inspect rendered YAML.
#1 Best Overall
For example, a basic local review can begin with helm lint ./my-chart and helm template my-release ./my-chart -f values-staging.yaml. The second command renders the chart with that values file; send or save the output for the validators and policy checks selected by your team.
How do you find and publish Helm charts?
Artifact Hub and command-line discovery
Artifact Hub is a discovery service for finding charts and viewing chart metadata, including security information. Helm’s quickstart describes it as a place to discover charts. From the CLI, helm search hub searches Artifact Hub; check the chart’s publisher, documentation, version, and security details before relying on a listing.
Traditional chart repositories
helm repo manages traditional index-based chart repositories. This workflow relies on repository metadata and is distinct from OCI registry distribution. It remains an option when your existing chart consumers and publishing process use indexed repositories.
OCI registries and ORAS
OCI-capable container registries can store and share Helm chart packages using oci:// references. Helm’s OCI support is enabled by default starting with Helm 3.8.0. Registry authentication, retention, and access controls depend on the registry provider, so configure those using that provider’s documentation. Artifact Hub also documents using ORAS to push repository metadata for OCI-hosted chart repositories; ORAS is relevant to that metadata workflow, not a replacement for Helm’s chart authoring commands.

helm verify can verify a chart when its publisher supplies the required provenance material. Provenance is useful when chart integrity and publisher verification are part of your distribution requirements; packaging alone does not establish that a consumer can verify a chart’s origin.
Which tools help with multi-release workflows and chart CI?
Helmfile
Helmfile provides declarative management for multiple Helm releases. Its helmfile lint command runs helm lint across charts or releases described in a Helmfile manifest, making it useful when a deployment is composed of several releases.
chart-testing (ct)
ct is commonly used in chart CI to lint and install-test charts that changed. It can help focus a pipeline on affected charts, but its current release and CI behavior should be checked against the project version you intend to adopt.
helm-unittest and other plugins
helm-unittest adds unit-style assertions for rendered chart templates. Helm plugins can extend the CLI, but they are separate projects: verify current maintenance, compatibility with your Helm version, and permissions before making a plugin part of a standard build.

The helm diff plugin is useful for reviewing release changes before an upgrade. Because it is a plugin rather than a built-in Helm command, confirm its maintenance and compatibility in your environment before relying on it for release approval.
How can you validate rendered manifests and check security?
Render first, then choose validators based on the question you need answered. Schema validation asks whether resources match Kubernetes API schemas; best-practice linting flags configuration concerns; security and policy analyzers apply their own rules. These checks complement Helm syntax validation rather than replacing it.
Schema validation: kubeconform and kubeval
kubeconform validates rendered manifests against Kubernetes schemas. Pin or otherwise align the schemas with the Kubernetes versions your chart supports; a schema check against the wrong version can produce misleading results. kubeval is an older rendered-manifest schema validator, so consider kubeconform for an actively maintained workflow and verify the current project status before selecting either.
Configuration checks: KubeLinter and Polaris
KubeLinter analyzes Kubernetes YAML and Helm output for configuration best practices. Polaris provides another perspective on Kubernetes configuration best practices. They can surface useful issues, but neither is a substitute for checking your own requirements for values, RBAC, labels, annotations, CRDs, dependencies, and supported Kubernetes versions.

Security and policy analyzers
Checkov, Datree, KICS, KubeLinter, Kubeaudit, Kubescape, and Terrascan have been examined as chart or Kubernetes analyzers in a cited study. The tool name alone does not establish which rules apply to your chart: compare rule coverage, false-positive handling, CI output, and maintenance before standardizing on one.
For organization-specific requirements, Conftest with Open Policy Agent (OPA) can enforce policies against rendered manifests. Keep policy definitions and policy tests alongside the chart so changes to chart output and rules can be reviewed together.

A useful pipeline separates chart-level checks from checks on the rendered resources and from tests that require a cluster. Run the same representative values and Kubernetes-version assumptions that matter to the chart’s supported deployments.
- Scaffold and maintain with Helm conventions. Use Helm chart structure, values, templates, and dependency practices deliberately.
- Lint the chart. Run
helm lint ./path/to/chartand review values, dependencies, labels and annotations, CRDs, RBAC, and chart structure. - Render representative configurations. Run
helm template RELEASE_NAME ./path/to/chart -f path/to/values.yamlfor the values combinations your chart supports. If the chart supports multiple meaningful configurations, render each one you intend to validate. - Validate and scan the rendered YAML. Feed the output into a schema validator configured for supported Kubernetes versions, then run selected configuration, security, and organization-policy checks. Review findings rather than assuming every warning is a defect.
- Install and run chart tests. In an ephemeral or staging cluster, install the chart and run
helm test RELEASE_NAME. This exercises chart-defined tests against an installed release. - Package and provide verification material as required. Use
helm package; attach provenance when consumers need to verify chart integrity. - Publish and expose metadata. Publish to an OCI registry or a traditional chart repository. Use Artifact Hub for discovery where appropriate, including the ORAS metadata workflow for OCI-hosted chart repositories.
- Operate releases with review and recovery controls. Use Helm or Helmfile to manage releases, inspect status and history, review changes before upgrades, and retain a rollback path.
How should you choose among the tools?
Start with the checks your release process actually needs, then evaluate candidates against the same rendered charts and CI environment. A compact set that gives clear, actionable results is usually easier to maintain than a large stack of overlapping scanners.
Quick Recap
- Input: Does the tool inspect chart source and templates, rendered manifests, an installed release, or registry metadata?
- Compatibility: Can schema and policy checks reflect the Kubernetes versions and APIs your chart supports?
- Coverage: Does the tool handle your values configurations, dependencies, CRDs, RBAC, and required policy rules?
- CI usability: Are exit codes, reports, and false-positive handling suitable for automated review?
- Maintenance and trust: Is the project maintained, compatible with your Helm version, and acceptable in terms of permissions and provenance needs?
- Workflow fit: Do you need single-chart commands, multi-release orchestration, GitOps integration, or OCI distribution?
