Introduction¶

This chart bootstraps a Whereabouts deployment on a Kubernetes cluster using the Helm package manager.

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

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

Prerequisites¶

Kubernetes 1.19+
Helm 3.2.0+
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:

helm install my-release bitnami/whereabouts

The command deploys Whereabouts 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.

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

helm install my-release \
  --set schedulerName=high-priority \
    bitnami/whereabouts

The above command sets the Whereabouts scheduler to high-priority.

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/whereabouts

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.

Host configuration¶

Once installed, the helm chart will modify configuration files in the host nodes of the Kubernetes cluster. Ensure that the cluster allows root and privileged deployments.

Once the whereabouts configuration is installed, check the upstream Kubernetes documentation on how to modify the network settings of the cluster.

Important: Double check that the host CNI binary and configuration directories are properly configured, or the deployment will fail. This is done using the hostCNINetDir and hostCNIBinDir values.

Image¶

The image parameter allows specifying which image will be pulled for the chart.

Private registry¶

If you configure the image value to one in a private registry, you will need to specify an image pull secret.

Manually create image pull secret(s) in the namespace. See this YAML example reference. Consult your image registry's documentation about getting the appropriate secret.
Note that the imagePullSecrets configuration value cannot currently be passed to helm using the --set parameter, so you must supply these using a values.yaml file, such as:
```
imagePullSecrets:
  - name: SECRET_NAME
```
Install the chart

Setting Pod's affinity¶

This chart allows you to set your custom affinity using the affinity parameter. Find more information about Pod's affinity in the kubernetes documentation.

As an alternative, you can use 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.
