## Prerequisites

* Install the follow packages: ``git``, ``kubectl``, ``helm``, ``helm-docs``. See this [tutorial](https://docs.victoriametrics.com/helm/requirements/).
* PV support on underlying infrastructure

## Chart Details

This chart will do the following:

* Rollout victoria metrics gateway

## How to install

Access a Kubernetes cluster.

### Setup chart repository (can be omitted for OCI repositories)

Add a chart helm repository with follow commands:

```console
helm repo add vm https://victoriametrics.github.io/helm-charts/

helm repo update
```
List versions of `vm/victoria-metrics-gateway` chart available to installation:

```console
helm search repo vm/victoria-metrics-gateway -l
```

### Install `victoria-metrics-gateway` chart

Export default values of `victoria-metrics-gateway` chart to file `values.yaml`:

  - For HTTPS repository

    ```console
    helm show values vm/victoria-metrics-gateway > values.yaml
    ```
  - For OCI repository

    ```console
    helm show values oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-gateway > values.yaml
    ```

Change the values according to the need of the environment in ``values.yaml`` file.

Test the installation with command:

  - For HTTPS repository

    ```console
    helm install vmg vm/victoria-metrics-gateway -f values.yaml -n NAMESPACE --debug --dry-run
    ```

  - For OCI repository

    ```console
    helm install vmg oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-gateway -f values.yaml -n NAMESPACE --debug --dry-run
    ```

Install chart with command:

  - For HTTPS repository

    ```console
    helm install vmg vm/victoria-metrics-gateway -f values.yaml -n NAMESPACE
    ```

  - For OCI repository

    ```console
    helm install vmg oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-gateway -f values.yaml -n NAMESPACE
    ```

Get the pods lists by running this commands:

```console
kubectl get pods -A | grep 'vmg'
```

Get the application by running this command:

```console
helm list -f vmg -n NAMESPACE
```

See the history of versions of `vmg` application with command.

```console
helm history vmg -n NAMESPACE
```

# How to use [JWT signature verification](https://docs.victoriametrics.com/vmgateway#jwt-signature-verification)

Kubernetes best-practice is to store sensitive configuration parts in secrets. For example, 2 keys will be stored as:
```yaml
apiVersion: v1
data:
  key: "<<KEY_DATA>>"
kind: Secret
metadata:
  name: key1
---
apiVersion: v1
data:
  key: "<<KEY_DATA>>"
kind: Secret
metadata:
  name: key2
```

In order to use those secrets it is needed to:
- mount secrets into pod
- provide flag pointing to secret on disk

Here is an example `values.yml` file configuration to achieve this:
```yaml
auth:
  enable: true

extraVolumes:
  - name: key1
    secret:
      secretName: key1
  - name: key2
    secret:
      secretName: key2

extraVolumeMounts:
  - name: key1
    mountPath: /key1
  - name: key2
    mountPath: /key2

extraArgs:
  envflag.enable: "true"
  envflag.prefix: VM_
  loggerFormat: json
  auth.publicKeyFiles: "/key1/key,/key2/key"
```
Note that in this configuration all secret keys will be mounted and accessible to pod.
Please, refer to [this](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.19/#secretvolumesource-v1-core) doc to see all available secret source options.

## How to uninstall

Remove application with command.

```console
helm uninstall vmg -n NAMESPACE
```

## Documentation of Helm Chart

Install ``helm-docs`` following the instructions on this [tutorial](https://docs.victoriametrics.com/helm/requirements/).

Generate docs with ``helm-docs`` command.

```bash
cd charts/victoria-metrics-gateway

helm-docs
```

The markdown generation is entirely go template driven. The tool parses metadata from charts and generates a number of sub-templates that can be referenced in a template file (by default ``README.md.gotmpl``). If no template file is provided, the tool has a default internal template that will generate a reasonably formatted README.

## Parameters

The following tables lists the configurable parameters of the chart and their default values.

Change the values according to the need of the environment in ``victoria-metrics-gateway/values.yaml`` file.

<table class="helm-vars">
  <thead>
    <th class="helm-vars-key">Key</th>
