Two journeys, one shared future. Your contribution helps my daughter pursue higher education and helps me continue creating thoughtful, accessible open-source tools—free for everyone to use.

Helm / Chart authoring

Shape the values.
Generate the chart.

Configure a Kubernetes workload and turn it into a documented Helm chart with reusable values, templates, schema validation, and tests.

Chart settings

Chart identity Metadata written to Chart.yaml and the generated README.

Helm chart API Choose the chart format written to Chart.yaml.

Chart API v3 is experimental. It requires Helm 4 and the HELM_EXPERIMENTAL_CHART_V3=1 feature gate. Support varies between Helm 4 releases, so use v2 for production charts.

Chart name Lowercase DNS label used as the chart directory. Chart version Semantic version for the chart package. Description Application version Kubernetes compatibility Optional Helm semantic-version constraint. Maintainer Source URL

Workload Choose the controller and container defaults exposed as values.

DeploymentStateless replicas StatefulSetStable identity DaemonSetOne pod per node

Image repository Default image tag Pull policy Replica count Container port Environment variables One NAME=value pair per line. Values remain strings.

Chart components Optional templates are controlled through values.yaml switches.

ServiceExpose the workload inside the cluster.

Service type Service port Service annotations One key=value annotation per line. Blank lines and lines starting with # are ignored.

IngressRoute a path, optionally for a specific host.

Ingress class Include host Disable to match requests for any host. Host Path Ingress annotations One key=value annotation per line. Blank lines and lines starting with # are ignored.

Horizontal autoscalingGenerate an autoscaling/v2 HPA.

Minimum replicas Maximum replicas Target CPU utilization

Pod disruption budgetProtect availability during voluntary evictions.

Minimum available An integer or percentage such as 50%.

ServiceAccountCreate a dedicated account for the workload.

Annotations One key=value annotation per line. Blank lines and lines starting with # are ignored.

Runtime defaults Safe starting values that chart consumers can override.

What the builder creates

A maintainable starting point, not a black box.

Chart metadata

A stable chart API v2 or experimental v3 definition with versions, compatibility, maintainers, and source links.

Values and schema

Documented defaults paired with a JSON Schema that catches invalid chart configuration early.

Composable templates

Namespaced helpers, standard Kubernetes labels, conditional components, release notes, and a connection test.

Use your chart locally

From downloaded ZIP to a running release.

Helm can lint and render the chart without a cluster. Installing, upgrading, testing, and inspecting a release use your active Kubernetes context.

Before you begin

Install the Helm CLI and check its version. Before cluster operations, confirm that kubectl points to the intended context.

helm version --short
kubectl config current-context

Install Helm

01

Unpack the chart

Use the downloaded archive name. The extracted directory matches the chart name configured above.
```
unzip web-application-0.1.0.zip
cd web-application
```
02

Validate and render

Lint the chart, then inspect the Kubernetes manifests locally without changing anything in a cluster.
```
helm lint --strict .
helm template my-release . \
  --namespace demo \
  --debug > rendered.yaml
```
03

Install or upgrade

Use one repeatable command for the first installation and later chart or values changes.
```
helm upgrade --install my-release . \
  --namespace demo \
  --create-namespace \
  --values values.yaml
```

Inspect and clean up

Check the release, run its generated connection test, and uninstall it when the local workflow is complete.

helm status my-release --namespace demo
helm get manifest my-release --namespace demo
helm test my-release --namespace demo
helm uninstall my-release --namespace demo

Using experimental chart API v3?

Use Helm 4 and set the feature flag in the same terminal before running lint, template, install, or upgrade commands.
