## ⚠️ 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 [Prometheus](https://prometheus.io) Deployment in a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

## Prerequisites

- Kubernetes 1.23+
- Helm 3.8.0+
- PV provisioner support in the underlying infrastructure
- ReadWriteMany volumes for deployment scaling

## Installing the Chart

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

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

> 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 Prometheus 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

### Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcesPreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/).

### [Rolling VS Immutable tags](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-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.

### Deploy extra resources

There are cases where you may want to deploy extra objects, such a ConfigMap containing your app's configuration or some extra deployment with a micro service used by your app. For covering this case, the chart allows adding the full specification of other objects using the `extraDeploy` parameter.

### Backup and restore

To back up and restore Helm chart deployments on Kubernetes, you need to back up the persistent volumes from the source deployment and attach them to a new deployment using [Velero](https://velero.io/), a Kubernetes backup/restore tool. Find the instructions for using Velero in [this guide](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-backup-restore-deployments-velero-index.html).

### Setting Pod's affinity

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

As an alternative, you can use 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 `XXX.podAffinityPreset`, `XXX.podAntiAffinityPreset`, or `XXX.nodeAffinityPreset` parameters.

### Integrate Prometheus and Alertmanager with Thanos

You can integrate Prometheus & Alertmanager with Thanos using this chart and the [Bitnami Thanos chart](https://github.com/bitnami/charts/tree/main/bitnami/thanos) following the steps below:

> Note: in this example we will use MinIO&reg; (subchart) as the Objstore. Every component will be deployed in the "monitoring" namespace.

- Create a **values.yaml** like the one below for Thanos:

```yaml
objstoreConfig: |-
  type: s3
  config:
    bucket: thanos
    endpoint: {{ include "thanos.minio.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local:9000
    access_key: minio
    secret_key: minio123
    insecure: true
query:
  dnsDiscovery:
    sidecarsService: prometheus-thanos
    sidecarsNamespace: monitoring
bucketweb:
  enabled: true
compactor:
  enabled: true
storegateway:
  enabled: true
ruler:
  enabled: true
  alertmanagers:
    - http://prometheus-alertmanager.monitoring.svc.cluster.local:9093
  config: |-
    groups:
      - name: "metamonitoring"
        rules:
          - alert: "PrometheusDown"
            expr: absent(up{prometheus="monitoring/prometheus"})
metrics:
  enabled: true
  serviceMonitor:
    enabled: true
minio:
  enabled: true
  auth:
    rootPassword: minio123
    rootUser: minio
  monitoringBuckets: thanos
  accessKey:
    password: minio
  secretKey:
    password: minio123
```

- Install Prometheus and Thanos charts:

For Helm 3:

```console
kubectl create namespace monitoring
helm install prometheus \
    --set prometheus.thanos.create=true \
    --namespace monitoring \
    oci://REGISTRY_NAME/REPOSITORY_NAME/prometheus
helm install thanos \
    --values values.yaml \
    --namespace monitoring \
    oci://REGISTRY_NAME/REPOSITORY_NAME/thanos
```

> 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`.

That's all! Now you have Thanos fully integrated with Prometheus and Alertmanager.

### Integrate Prometheus with Grafana Mimir

You can integrate Prometheus with Grafana Mimir using this chart and the [Bitnami Grafana Mimir chart](https://github.com/bitnami/charts/tree/main/bitnami/grafana-mimir) adding a `remoteWrite` entry:

- Create a **values.yaml** like the one below for Prometheus:

```yaml
server:
  remoteWrite:
    - url: http://grafana-mimir-gateway.svc.cluster.local/api/v1/push
      headers:
        X-Scope-OrgID: demo
```

- Install Prometheus and Grafana Mimir charts:

For Helm 3:

```console
kubectl create namespace monitoring
helm install prometheus \
    --values values.yaml \
    --namespace monitoring \
    oci://REGISTRY_NAME/REPOSITORY_NAME/prometheus
helm install grafana-mimir \
    oci://REGISTRY_NAME/REPOSITORY_NAME/grafana-mimir
```

> 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`.

That's all! Now you have Prometheus integrated with Grafana Mimir.

### Integrate Prometheus with Grafana

You can integrate Prometheus with Grafana Dashboard using this chart and the [Bitnami Grafana chart](https://github.com/bitnami/charts/tree/main/bitnami/grafana) just adding the prometheus datasources:

- Create a **values.yaml** like the one below for Grafana:

```yaml
datasources:
  secretDefinition:
    apiVersion: 1
    datasources:
      - name: Prometheus
        type: prometheus
        access: proxy
        orgId: 1
        url: http://prometheus.monitoring.svc.cluster.local
        version: 1
        editable: true
        isDefault: true
      - name: Alertmanager
        uid: alertmanager
        type: alertmanager
        access: proxy
        orgId: 1
        url: http://prometheus-alertmanager.monitoring.svc.cluster.local:9093
        version: 1
        editable: true
```

- Install Prometheus and Grafana charts:

For Helm 3:

```console
kubectl create namespace monitoring
helm install prometheus \
    --namespace monitoring \
    oci://REGISTRY_NAME/REPOSITORY_NAME/prometheus
helm install grafana \
    --values values.yaml \
    --namespace monitoring \
    oci://REGISTRY_NAME/REPOSITORY_NAME/grafana
```

> 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`.

### How to add new targets

By default this helm chart will monitor its own targets: prometheus and alertmanager. Additional ones can be added setting a list with the [scrape_configs](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config) in the value `server.extraScrapeConfigs`. Here there is a simple example for wordpress (deployed in the default namespace):

```yaml
server:
  extraScrapeConfigs:
    - job_name: wordpress
      kubernetes_sd_configs:
        - role: endpoints
          namespaces:
            names:
            - default
      metrics_path: /metrics
      relabel_configs:
        - source_labels:
            - job
          target_label: __tmp_wordpress_job_name

          target_label: pod
        - source_labels:
            - __meta_kubernetes_pod_container_name
          target_label: container
        - action: drop
          source_labels:
            - __meta_kubernetes_pod_phase
          regex: (Failed|Succeeded)
        - source_labels:
            - __meta_kubernetes_service_name
          target_label: job
          replacement: ${1}
        - target_label: endpoint
          replacement: metrics
        - source_labels:
            - __address__
          target_label: __tmp_hash
          modulus: 1
          action: hashmod
        - source_labels:
            - __tmp_hash
          regex: 0
          action: keep
```

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

```console
helm install my-release --set alertmanager.enabled=true \
  oci://REGISTRY_NAME/REPOSITORY_NAME/prometheus
```

> 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 install Prometheus chart with Alertmanager.

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/prometheus
```

> 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/prometheus/values.yaml)

## Upgrading

### To 1.4.0

This version introduces image verification for security purposes. To disable it, set `global.security.allowInsecureImages` to `true`. More details at [GitHub issue](https://github.com/bitnami/charts/issues/30850).

### To 1.0.0

This major bump changes the following security defaults:

- `runAsGroup` is changed from `0` to `1001`
- `readOnlyRootFilesystem` is set to `true`
- `resourcesPreset` is changed from `none` to the minimum size working in our test suites (NOTE: `resourcesPreset` is not meant for production usage, but `resources` adapted to your use case).
- `global.compatibility.openshift.adaptSecurityContext` is changed from `disabled` to `auto`.

This could potentially break any customization or init scripts used in your deployment. If this is the case, change the default values to the previous ones.
