```

Looking to use HAProxy 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 [HAProxy](https://github.com/haproxytech/haproxy) Deployment in 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+

## Installing the Chart

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

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

> 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 haproxy 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 `resourcePreset` 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://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.

### Configure HAProxy

By default, HAProxy is deployed with a sample, non-functional, configuration. You will need to edit the following values to adapt it to your use case:

- Set the configuration to be injected in the `haproxy.cfg` file by changing the `configuration` parameter. Alternatively, you can provide an existing ConfigMap with `haproxy.cfg` by using the `existingConfigmap` parameter.

  The example below configures HAProxy to forward all requests to port 8080 to a service called *service1:8080* (it is assumed that this is accessible from inside the cluster).

  ```yaml
  configuration: |
    global
      log 127.0.0.1 local2
      maxconn 4096

    defaults
      mode http
      log global
      option httplog
      option dontlognull
      option http-server-close
      option forwardfor except 127.0.0.0/8
      option redispatch
      retries 3
      timeout http-request 20s
      timeout queue 1m
      timeout connect 10s
      timeout client 1m
      timeout server 1m
      timeout http-keep-alive 30s
      timeout check 10s
      maxconn 3000

    frontend fe_http
      option forwardfor except 127.0.0.1
      option httpclose
      bind *:8080
      default_backend be_http

    backend be_http
      balance roundrobin
      server nginx service:8080 check port 8080
  ```

- Based on your HAProxy configuration, edit the `containerPorts` and `service.ports` parameters. In the `containerPorts` parameter, set all the ports that the HAProxy configuration uses, and in the `service.ports` parameter, set the ports to be externally exposed.

  For the example above, the configuration would look like this:

  ```yaml
  service:
    - name: http
      port: 80 # We use port 80 in the service
      targetPort: http

  containerPorts:
    - name: http
      containerPort: 8080
  ```

### Add extra environment variables

To add extra environment variables (useful for advanced operations like custom init scripts), use the `extraEnvVars` property.

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

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

### Use Sidecars and Init Containers

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

> NOTE: This Helm chart already includes sidecar containers for the Prometheus exporters (where applicable). These can be activated by adding the `--enable-metrics=true` parameter at deployment time. The `sidecars` parameter should therefore only be used for any extra sidecar containers.

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/).

### Set Pod affinity

This chart allows you to set custom Pod 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.

| --------------------------------------------- | ------------------------------------------------------------------------------------------------------------------- | ------- |
| `serviceAccount.create`                       | Specifies whether a ServiceAccount should be created                                                                | `true`  |
| `serviceAccount.name`                         | Name of the service account to use. If not set and create is true, a name is generated using the fullname template. | `""`    |
| `serviceAccount.automountServiceAccountToken` | Automount service account token for the server service account                                                      | `false` |
| `serviceAccount.annotations`                  | Annotations for service account. Evaluated as a template. Only used if `create` is `true`.                          | `{}`    |
| `serviceAccount.create`                       | Specifies whether a ServiceAccount should be created                                                                | `true`  |
| `serviceAccount.name`                         | The name of the ServiceAccount to use.                                                                              | `""`    |

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

```console
helm install my-release \
  --set service.type=LoadBalancer \
    oci://REGISTRY_NAME/REPOSITORY_NAME/haproxy
```

> 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 HAProxy service type as LoadBalancer.

> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.

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

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

> 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/haproxy/values.yaml)

## Upgrading

### 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.
