## [v0.12.0](https://github.com/DaemonDude23/helmizer/releases/tag/v0.12.0)

July 27 2022

**Bugfixes**

- Fixed missing support for `secretGenerator` despite having something in [`secretGenerator` examples](./examples/secretGenerator/).
- Don't crash if `helmizer.version` and/or `helmizer.sort-keys` are not defined in the `helmizer.yaml` config... or practically anything. Omit the `helmizer` section of the config if you wish.

**Enhancements**

- Added `--no-sort-keys` CLI flag to disable key sorting of _all_ keys output kustomization.yaml on the CLI.

**Housekeeping**

- Added READMEs to example folders that didn't have them, and fixed other example READMEs.
- Bumped to latest versions in `requirements.txt` for no particular reason.
- Updated each relevant line with _type hinting_ for future experimentation.
- `pre-commit` config updates.

## About

**TLDR**

Generates a `kustomization.yaml` file, optionally providing the ability to run commands (e.g. `helm template`) on your OS prior to generating a kustomization, and will compose the kustomization fields that deal with file paths (e.g. `resources`) with glob-like features, as well as pass-through all other kustomization configuration properties. No need to explicitly enumerate every file to be kustomized individually.
Generates a `kustomization.yaml` file, optionally providing the ability to run commands (e.g. `helm template`) on your OS prior to generating a kustomization, and will compose the kustomization fields that deal with file paths (e.g. `resources`) with glob-like features, as well as pass-through all other kustomization configuration properties. No need to explicitly enumerate every file to be 'kustomized' individually.

It takes a config file as input, telling **Helmizer** if you want to run any commands. Then if you give it one or more directories for `resources`, for example, it will recursively lookup all of those files and render them into your kustomization.yaml. Want to skip including one file like `templates/secret.yaml`? Just add the relative path to `helmizer.ignore` to `helmizer.yaml`.

I began transitioning my `helm` charts to local manifests via [`helm template`](https://helm.sh/docs/helm/helm_template/), which were then applied to the cluster separately via [Kustomize](https://kustomize.io/). I didn't enjoy having to manually manage the relative paths to files in the **kustomization**. I wanted a repeatable process to generate **Kubernetes** manifests from a helm chart, _and_ tack on any patches or related resources later with a single command. Thus, **helmizer**. **But [Helm](https://helm.sh/) is in no way required to make this tool useful** - have it walk your raw manifests as well. This is just a wrapper that allows combining steps, and glob-like behavior, to managing `kustomization.yaml` files.

### Installation
## Installation
For local installation/use of the raw script, I use a local virtual environment to isolate dependencies:
```bash
git clone https://github.com/DaemonDude23/helmizer.git -b v0.11.0
git clone https://github.com/DaemonDude23/helmizer.git -b v0.12.0
cd helmizer
