- if deployed by manifest, add env `FELIX_WORKLOADSOURCESPOOFING` with value `Any` in `spec.template.spec.containers.env` for daemonset `calico-node`. (This will allow PODs with specified annotation to skip the rpf check. )

### GKE notes

On GKE, 'kube-system' is required.

If using `helm template`, `--set cni.cniBinDir=/home/kubernetes/bin` is required - with `helm install`

	installer := install.NewInstaller(&serverConfig.InstallConfig, readyFlag)

	// the CNI binary installed.
	if err := installer.Run(ctx); err != nil {
		if errors.Is(err, context.Canceled) || errors.Is(err, context.DeadlineExceeded) {
