## ⚠️ Important Notice: Upcoming changes to the Bitnami Catalog

Beginning August 28th, 2025, Bitnami will evolve its public catalog to offer a curated set of hardened, security-focused images under the new [Bitnami Secure Images initiative](https://news.broadcom.com/app-dev/broadcom-introduces-bitnami-secure-images-for-production-ready-containerized-applications). As part of this transition:

- Granting community users access for the first time to security-optimized versions of popular container images.
- Bitnami will begin deprecating support for non-hardened, Debian-based software images in its free tier and will gradually remove non-latest tags from the public catalog. As a result, community users will have access to a reduced number of hardened images. These images are published only under the “latest” tag and are intended for development purposes
- Starting August 28th, over two weeks, all existing container images, including older or versioned tags (e.g., 2.50.0, 10.6), will be migrated from the public catalog (docker.io/bitnami) to the “Bitnami Legacy” repository (docker.io/bitnamilegacy), where they will no longer receive updates.
- For production workloads and long-term support, users are encouraged to adopt Bitnami Secure Images, which include hardened containers, smaller attack surfaces, CVE transparency (via VEX/KEV), SBOMs, and enterprise support.

These changes aim to improve the security posture of all Bitnami users by promoting best practices for software supply chain integrity and up-to-date deployments. For more details, visit the [Bitnami Secure Images announcement](https://github.com/bitnami/containers/issues/83267).

## Introduction

Bitnami charts for Helm are carefully engineered, actively maintained and are the quickest and easiest way to deploy containers on a Kubernetes cluster that are ready to handle production workloads.

This chart bootstraps a [Grafana Alloy](https://github.com/grafana/alloy) deployment in a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

## Prerequisites

- Kubernetes 1.23+
- Helm 3.8.0+

## Installing the Chart

To install the chart with the release name `my-release`:

```console
helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/grafana-alloy
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

The command deploys Grafana Alloy on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.

> **Tip**: List all releases using `helm list`

## Configuration and installation details

### Alloy configuration

The Bitnami Grafana Alloy chart allows [providing a configuration](https://grafana.com/docs/alloy/latest/get-started/configuration-syntax/) using ConfigMaps. This is done using the `alloy.configuration` parameter. It is also possible to append the provided settings with the default configuration by using the `alloy.extraConfig` parameter. In the example below we add extra configuration parameters:

```yaml
alloy:
  extraConfig:|
    loki.write "local_loki" {
      endpoint {
        url = "http://loki:3100/loki/api/v1/push"
      }
  }
```

It is also possible to use an existing ConfigMap using the `alloy.existingConfigMap` parameter.

### [Rolling VS Immutable tags](https://docs.vmware.com/en/VMware-Tanzu-Application-Catalog/services/tutorials/GUID-understand-rolling-tags-containers-index.html)

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Additional environment variables

In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the `extraEnvVars` property.

```yaml
alloy:
  extraEnvVars:
    - name: LOG_LEVEL
      value: error
```

Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the `extraEnvVarsCM` or the `extraEnvVarsSecret` values.

### Sidecars

If additional containers are needed in the same pod as Grafana Alloy (such as additional metrics or logging exporters), they can be defined using the `sidecars` parameter.

```yaml
sidecars:
- name: your-image-name
  image: your-image
  imagePullPolicy: Always
  ports:
  - name: portname
    containerPort: 1234
```

If these sidecars export extra ports, extra port definitions can be added using the `service.extraPorts` parameter (where available), as shown in the example below:

```yaml
service:
  extraPorts:
  - name: extraPort
    port: 11311
    targetPort: 11311
```

If additional init containers are needed in the same pod, they can be defined using the `initContainers` parameter. Here is an example:

```yaml
initContainers:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
        containerPort: 1234
```

Learn more about [sidecar containers](https://kubernetes.io/docs/concepts/workloads/pods/) and [init containers](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/).

### Pod affinity

This chart allows you to set your custom affinity using the `affinity` parameter. Find more information about Pod affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, use one of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

### Prometheus metrics

This chart can be integrated with Prometheus by setting `metrics.enabled` to `true`. This will expose Grafana Alloy native Prometheus endpoint in a metrics service that can be configured under the `metrics.service` section. It will have the necessary annotations to be automatically scraped by Prometheus.

#### Prometheus requirements

It is necessary to have a working installation of Prometheus or Prometheus Operator for the integration to work. Install the [Bitnami Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/prometheus) or the [Bitnami Kube Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/kube-prometheus) to easily have a working Prometheus in your cluster.

#### Integration with Prometheus Operator

The chart can deploy `ServiceMonitor` objects for integration with Prometheus Operator installations. To do so, set the value `metrics.serviceMonitor.enabled=true`. Ensure that the Prometheus Operator `CustomResourceDefinitions` are installed in the cluster or it will fail with the following error:

```text
no matches for kind "ServiceMonitor" in version "monitoring.coreos.com/v1"
```

Install the [Bitnami Kube Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/kube-prometheus) for having the necessary CRDs and the Prometheus Operator.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
helm install my-release \
  --set aggregator.port=24444 oci://REGISTRY_NAME/REPOSITORY_NAME/fluentd
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

The above command sets the aggregators to listen on port 24444.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

```console
helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/fluentd
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
> **Tip**: You can use the default [values.yaml](https://github.com/bitnami/charts/tree/main/bitnami/fluentd/values.yaml)
