--------------------------------

### Add Helmify to Makefile (Operator-SDK >= v1.23.0)

Source: https://github.com/arttor/helmify/blob/main/README.md

Integrate Helmify into your Makefile for newer versions of Operator-SDK. This defines HELMIFY using a local binary path and provides a target to download helmify if it's not present. The 'helm' target uses kustomize output piped to Helmify.

```makefile
HELMIFY ?= $(LOCALBIN)/helmify

.PHONY: helmify
helmify: $(HELMIFY) ## Download helmify locally if necessary.
$(HELMIFY): $(LOCALBIN)
	test -s $(LOCALBIN)/helmify || GOBIN=$(LOCALBIN) go install github.com/arttor/helmify/cmd/helmify@latest

helm: manifests kustomize helmify
	$(KUSTOMIZE) build config/default | $(HELMIFY)
```

--------------------------------

### Create Helm Chart Recursively from Directory

Source: https://github.com/arttor/helmify/blob/main/README.md

Employ the -r flag along with the -f flag to recursively scan a directory for YAML files and generate a Helm chart. The chart will be created in the 'mychart' directory.

```shell
helmify -f /my_directory -r mychart
```

--------------------------------

### Add Helmify to Makefile (Operator-SDK < v1.23.0)

Source: https://github.com/arttor/helmify/blob/main/README.md

Integrate Helmify into your Makefile for older versions of Operator-SDK. This involves defining the HELMIFY path and adding a 'helmify' target that depends on 'go-get-tool'. The 'helm' target then uses kustomize output piped to Helmify.

```makefile
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)
```

--------------------------------

### Create Helm Chart from Multiple Sources

Source: https://github.com/arttor/helmify/blob/main/README.md

Combine multiple file and directory paths using the -f flag to generate a Helm chart. This allows for flexible input selection. The chart will be created in the 'mychart' directory.

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

--------------------------------

### Create Helm Chart from Single File

Source: https://github.com/arttor/helmify/blob/main/README.md

Specify a single YAML file using the -f flag to generate a Helm chart. The chart will be created in the 'mychart' directory.

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

--------------------------------

### Helmify Version Flag

Source: https://github.com/arttor/helmify/blob/main/README.md

```bash
helmify -version
```

--------------------------------

### Generate Helm Chart with Debug Output

Source: https://github.com/arttor/helmify/blob/main/README.md

Run Helmify with the -vv flag for verbose debug output, useful for inspecting logs and the generated chart.

```shell
cat test_data/k8s-operator-kustomize.output | go run ./cmd/helmify -vv mychart
```

--------------------------------

### Create Helm Chart from Single YAML via Pipe

Source: https://github.com/arttor/helmify/blob/main/README.md

Use this command to pipe a single Kubernetes manifest file into Helmify to generate a Helm chart. The chart will be created in a directory named 'mychart'.

```shell
cat my-app.yaml | helmify mychart
```

--------------------------------

### Helmify Verbose Output Flag

Source: https://github.com/arttor/helmify/blob/main/README.md

Enable verbose output, including WARN and INFO messages, by using the -v flag.

```bash
helmify -v
```

--------------------------------

### Helmify Usage with Chart Name

Source: https://github.com/arttor/helmify/blob/main/README.md

Basic usage of Helmify, specifying the chart name as an argument. The chart name is optional and defaults to 'chart'. It can be a directory path.

```

--------------------------------

### Helmify Original Name Flag

Source: https://github.com/arttor/helmify/blob/main/README.md

Use the object's original name instead of prefixing it with the chart's release name by using the -original-name flag.

```bash
helmify -original-name
```

--------------------------------

### Create Helm Chart from Multiple YAMLs via Pipe

Source: https://github.com/arttor/helmify/blob/main/README.md

Concatenate multiple YAML files from a directory using awk and pipe the output to Helmify to create a Helm chart. The chart will be generated in the 'mychart' directory.

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

--------------------------------

### Helmify Cert-Manager Version Flag

Source: https://github.com/arttor/helmify/blob/main/README.md

Specify the cert-manager subchart version using the -cert-manager-version flag. This is only useful when -cert-manager-as-subchart is also used. The default version is 'v1.12.2'.

```bash
helmify -cert-manager-version=v1.12.2
```

--------------------------------

### Helmify Very Verbose Output Flag

Source: https://github.com/arttor/helmify/blob/main/README.md

```

--------------------------------

### Helmify CRD Directory Flag

Source: https://github.com/arttor/helmify/blob/main/README.md

Place custom resource definitions (CRDs) in their own folder according to Helm 3 best practices using the -crd-dir flag. Note that CRD templating is not supported by Helm.

```bash
helmify -crd-dir
```
