ser2sock: Serial to Socket Redirector

This is a helm chart for ser2sock

TL;DR;

$ helm repo add k8s-at-home https://k8s-at-home.com/charts/
$ helm install k8s-at-home/ser2sock

Installing the Chart

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

helm install --name my-release k8s-at-home/ser2sock

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

A way to achieve this can be with nodeAffinity rules, for example:

affinity:
  nodeAffinity:
    requiredDuringSchedulingIgnoredDuringExecution:
      nodeSelectorTerms:
      - matchExpressions:
        - key: usb
          operator: In
          values:
          - alarmdecoder

... where a node with an attached Coral USB device is labeled with usb: alarmdecoder

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.

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

    k8s-at-home/ser2sock

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

helm install --name my-release -f values.yaml k8s-at-home/ser2sock

Read through the values.yaml file. It has several commented out suggested values.
