# Publish helm repo

## 1. Update Helm Version for release:

Update `Chart.yaml` file for fields:
- `appVersion`: for helm or k8s related changes
- `version`: for pinot related changes, remove `-SNAPSHOT` suffix to get to the release version, e.g. `0.3.4-SNAPSHOT` -> `0.3.4`.

## 2. Package Helm Charts

Run below command to package Pinot Chart.
```
helm package pinot
```
This step will generate a `pinot-${version}.tgz` file.

## 3. Index all the packages:

```
helm repo index .
```
This step will generate an `index.yaml` file which contains all the Charts information.

Update generated `index.yaml` accordingly:
- Revert the changes for all previous Charts;
- Change `entries.pinot.source` to `https://github.com/apache/pinot/tree/master/helm`.

## 4. Update Helm Version for development:

Update `Chart.yaml` file for making next `version` with `-SNAPSHOT` suffix. E.g. `0.3.4` -> `0.3.5-SNAPSHOT`
