helm install my-release oci://registry-1.docker.io/bitnamicharts/metallb
```

Looking to use MetalLB in production? Try [VMware Tanzu Application Catalog](https://bitnami.com/enterprise), the commercial edition of the Bitnami catalog.

## 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 [MetalLB Controller](https://metallb.universe.tf/community/) Controller Deployment and a [MetalLB Speaker](https://metallb.universe.tf/community/) Daemonset on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.23+
- Helm 3.8.0+
- Virtual IPs for Layer 2 or Route Reflector for BGP setup.

## Installing the Chart

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

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

> 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`.

These commands deploy metallb 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/).

### Prometheus metrics

This chart can be integrated with Prometheus by setting `*.metrics.enabled` (under the `controller`, `speaker` and `speaker.frr` sections) to true. This will expose the MetalLB native Prometheus port in both the containers and services. The services will also 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` (under the `controller`, `speaker` and `speaker.frr` sections). 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.

### [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.

To configure [MetalLB](https://metallb.universe.tf) please look into the configuration section [MetalLB Configuration](https://metallb.universe.tf/configuration/).

### 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).

### Example IP addresses to assing to the LoadBalancer configuration

```yaml
# The address-pools lists the IP addresses that MetalLB is
# allowed to allocate. You can have as many
# address pools as you want.
apiVersion: metallb.io/v1beta1
kind: IPAddressPool
metadata:
  # A name for the address pool. Services can request allocation
  # from a specific address pool using this name.
  name: first-pool
  namespace: metallb-system
spec:
  # A list of IP address ranges over which MetalLB has
  # authority. You can list multiple ranges in a single pool, they
  # will all share the same settings. Each range can be either a
  # CIDR prefix, or an explicit start-end range of IPs.
  addresses:
  - 192.168.10.0/24
  - 192.168.9.1-192.168.9.5
  - fc00:f853:0ccd:e799::/124
```

```console
helm install my-release \
  --set readinessProbe.successThreshold=5 \
    oci://REGISTRY_NAME/REPOSITORY_NAME/metallb
```

> 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 `readinessProbe.successThreshold` to `5`.

## Upgrading

### To 6.4.0

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 6.0.0

This major release includes the changes and features available in MetalLB from version 0.14.x. This new version includes some breaking changes like AddressPool removal or the several changes about the `webhook-server-cert secret`. For more details about MetaLB changes please visit [the release notes](https://metallb.universe.tf/release-notes/).

### To 5.0.0

This major bump changes the following security defaults:

- `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.

### To 4.0.0

This major release includes the changes and features available in MetalLB from version 0.13.0. Those changes include the deprecation of configmaps for configuring the service and using CRDs instead. If you are upgrading from a previous version, you can follow the official documentation on [how to migrate the configuration from a configMap to CRDs](https://metallb.universe.tf/#backward-compatibility).

### To 3.0.0

This major release renames several values in this chart and adds missing features, in order to be aligned with the rest of the assets in the Bitnami charts repository.

Affected values:

- `<controller/speaker>.prometheus` has been renamed as `<controller/speaker>.metrics`.
- To enable the Prometheus serviceMonitors, it is necessary to enable both `<controller/speaker>.metrics.enabled` and `<controller/speaker>.metrics.serviceMonitor.enabled`.
- Added the values section `<controller/speaker>.metrics.service`.
- `<controller/speaker>.securityContext` has been split as `<controller/speaker>.podSecurityContext` and `<controller/speaker>.containerSecurityContext`
- `controller.containerPort` has been renamed as `controller.containerPorts`.
- `speaker.daemonset.hostPorts.metrics` renamed as `speaker.containerPorts.metrics`
- `speaker.daemonset.terminationGracePeriodSeconds` renamed as speaker.terminationGracePeriodSeconds

### To 2.0.0

#### What changes were introduced in 2.0.0?

- The `.Values.prometheus` section was moved into the components `.Values.controller.prometheus` and `.Values.speaker.prometheus`
- The `prometheus.prometheusRule` which is used to toggle the deployment of the metallb alerts is moved under the root of the `.Values.prometheusRule`
- A globel `.Values.psp.create` and `.Values.rbac.create` was introduced together with the option of toggeling for each component. (global option overwrites component options)
  - `Values.controller.rbac.create` and `Values.controller.psp.create`
  - `Values.speaker.rbac.create` and `Values.speaker.psp.create`

#### Considerations when upgrading to 2.0.0

- Check if you used the `prometheus` section in you deployment.
- If you do so, place the configuration you made into the sections `controller.prometheus` and `speaker.prometheus`.
- `prometheusRule` should stay under the root of your values.

### To 1.0.0

[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.

#### What changes were introduced in 1.0.0?

- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts

#### Considerations when upgrading to 1.0.0

- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3
