chartify

chartify converts anything to a Helm chart and modifies a chart in-place so that you don't need to fork an upstream helm chart only for a few custom requirements.

chartify is a Go library that is primarily used by helmfile to let it convert Kuberntes resource YAMLs or kustomize into a helm chart, and apply various modifications to the resulting chart.

chartify is intended to be run immediately before running helm upgrade --install. For example, instead of forking a helm chart, you should be able to prepend a chartify step into your deployment job in your CD pipeline. chartify isn't intended to create a fork of a chart. The output of chartify is a helm chart that is pre-rendered with all the helm values provided to chartify.

Installation

Build from source

Build the CLI tool:

make build

Or build manually:

go build -o chartify ./cmd/chartify

Build the chart repo server:

make build/chartreposerver

Or build manually:

go build -o chartreposerver ./cmd/chartreposerver

Prerequisites

• Go 1.25.4+
• Helm v4.1.0 (helm command)
• Kustomize v5.8.0+ (kustomize command, optional, for kustomize integration)

CLI

Beyond it's usage with helmfile, it also provides a basic CLI application that can be run independently.

The simplest usage of the command is:

$ chartify $RELEASE $CHART -o $OUTPUT_DIR

Examples:

# Build and run with a Helm chart
make build
./chartify -o /tmp/output test-release testdata/charts/log

# Build and run with Kubernetes manifests
./chartify -o /tmp/output test-release testdata/kube_manifest_yml

See chartify -h or go run ./cmd/chartify -h for more information.
