Helmify

CLI that creates Helm charts from kubernetes manifests.

Helmify reads a list of supported k8s objects from stdin and converts it to a helm chart. Designed to generate charts for k8s operators but not limited to. See examples of charts generated by helmify.

Supports Helm >=v3.6.0

Usage

1. As pipe:

   cat my-app.yaml | helmify mychart

   Will create 'mychart' directory with Helm chart from yaml file with k8s objects.

   awk 'FNR==1 && NR!=1  {print "---"}{print}' /<my_directory>/*.yaml | helmify mychart

   Will create 'mychart' directory with Helm chart from all yaml files in <my_directory> directory.

2. From filesystem:

   helmify -f /my_directory/my-app.yaml mychart

   Will create 'mychart' directory with Helm chart from my_directory/my-app.yaml.

   helmify -f /my_directory mychart

   Will create 'mychart' directory with Helm chart from all yaml files in <my_directory> directory.

   helmify -f /my_directory -r mychart

   Will create 'mychart' directory with Helm chart from all yaml files in <my_directory> directory recursively.

   helmify -f ./first_dir -f ./second_dir/my_deployment.yaml -f ./third_dir  mychart

   Will create 'mychart' directory with Helm chart from multiple directories and files.

3. From kustomize output:

   kustomize build <kustomize_dir> | helmify mychart

   Will create 'mychart' directory with Helm chart from kustomize output.

Integrate to your Operator-SDK/Kubebuilder project

1. Open Makefile in your operator project generated by Operator-SDK or Kubebuilder.
2. Add these lines to Makefile:

• With operator-sdk version < v1.23.0

  HELMIFY = $(shell pwd)/bin/helmify
  helmify:
  	$(call go-get-tool,$(HELMIFY),github.com/arttor/helmify/cmd/helmify@v0.3.7)
  
  helm: manifests kustomize helmify
  	$(KUSTOMIZE) build config/default | $(HELMIFY)

• With operator-sdk version >= v1.23.0
