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 Deployment in a Kubernetes cluster using the Helm package manager.

Bitnami charts can be used with Kubeapps for deployment and management of Helm Charts in clusters.

Learn more about the default configuration of the chart.

Looking to use HAProxy in production? Try VMware Application Catalog, the enterprise edition of Bitnami Application Catalog.

Prerequisites¶

• Kubernetes 1.19+
• Helm 3.2.0+

Installing the Chart¶

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

helm install my-release bitnami/haproxy

The command deploys haproxy on the Kubernetes cluster in the default configuration. The Parameters section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart¶

To uninstall/delete the my-release deployment:

helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Parameters¶

Global parameters¶

Common parameters¶

Traffic Exposure Parameters¶

HAProxy Parameters¶

Other Parameters¶

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

helm install my-release \
  --set service.type=LoadBalancer \
    bitnami/haproxy

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,

helm install my-release -f values.yaml bitnami/haproxy

Tip: You can use the default values.yaml

Configuration and installation details¶

Rolling VS Immutable tags¶

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.
• 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.

Refer to the chart documentation for a more detailed configuration example.

Add extra environment variables¶

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

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. Similarly, extra init containers can be added using the initContainers parameter.

Refer to the chart documentation for more information on, and examples of, configuring and using sidecars and 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.

As an alternative, use one of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the bitnami/common chart. To do so, set the podAffinityPreset, podAntiAffinityPreset, or nodeAffinityPreset parameters.
