Installing the Chart

To install the chart with the release name multus

helm install multus k8s-at-home/multus

Uninstalling the Chart

To uninstall the multus deployment

helm uninstall multus

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

Configuration

Read through the values.yaml file. It has several commented out suggested values. Other values may be used from the values.yaml from the common library.

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

helm install multus \
  --set env.TZ="America/New York" \
    k8s-at-home/multus

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

helm install multus k8s-at-home/multus -f values.yaml

Custom configuration

Error setting up network for sandbox

If you remove multus by force, the helm uninstall hook will not be called. In this situation kubelet will still try to call multus to during the creation of every single pod. you wil see this error:

Failed to create pod sandbox: rpc error: code = Unknown desc = failed to setup network for sandbox

If you hit this problem you can manually remove multus config. For k3s you can do so with:

rm -rf  /var/lib/rancher/k3s/agent/etc/cni/net.d/*multus*
