piaware

This is a helm chart for piaware.

TL;DR;

$ helm repo add k8s-at-home https://k8s-at-home.com/charts/
$ helm install k8s-at-home/piaware

Installing the Chart

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

helm install --name my-release k8s-at-home/piaware

IMPORTANT NOTE: a piaware device must be accessible on the node where this pod runs, in order for this chart to function properly.

First, you will need to mount your piaware device into the pod, you can do so by adding the following to your values:

additionalVolumeMounts:
  - name: usb
    mountPath: /path/to/device

additionalVolumes:
  - name: usb
    hostPath:
      path: /path/to/device

Second you will need to set a nodeAffinity rule, for example:

affinity:
  nodeAffinity:
    requiredDuringSchedulingIgnoredDuringExecution:
      nodeSelectorTerms:
      - matchExpressions:
        - key: app
          operator: In
          values:
          - piaware

... where a node with an attached piaware USB device is labeled with app: piaware

Uninstalling the Chart

To uninstall/delete the my-release deployment:

helm delete my-release --purge

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

Read through the charts values.yaml file. It has several commented out suggested values. Additionally you can take a look at the common library values.yaml for more (advanced) configuration options.

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

helm install my-release \
  --set env.TZ="America/New_York" \
    k8s-at-home/piaware

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 k8s-at-home/piaware --values values.yaml 

image:
  tag: ...

NOTE

If you get

Error: rendered manifests contain a resource that already exists. Unable to continue with install: existing resource conflict: ...`

it may be because you uninstalled the chart with skipuninstall enabled, you need to manually delete the pvc or use existingClaim.

Upgrading an existing Release to a new major version

A major chart version change (like 4.0.1 -> 5.0.0) indicates that there is an incompatible breaking change potentially needing manual actions.

Upgrading from 2.x.x to 3.x.x

As of 3.0.0 this chart was migrated to a centralized common library, some values in values.yaml have changed.

Examples:

• service.port has been moved to service.port.port.
• persistence.type has been moved to controllerType.

Refer to the common library for more configuration options.
