That is, `--set some.field=true` should be passed, not `--set defaults.some.field=true`.

### Ambient

To enable ambient, you can use the ambient profile: `--set profile=ambient`.

#### Calico

For Calico, you must also modify the settings to allow source spoofing:

- if deployed by operator,  `kubectl patch felixconfigurations default --type='json' -p='[{"op": "add", "path": "/spec/workloadSourceSpoofing", "value": "Any"}]'`

The details for the deployment & installation of this plugin were pretty much lifted directly from the
[Calico CNI plugin](https://github.com/projectcalico/cni-plugin).

Specifically:

- The CNI installation script is containerized and deployed as a daemonset in k8s.  The relevant calico k8s manifests were used as the model for the istio-cni plugin's manifest:

  case "${KUBERNETES_CNI:-}" in 

    "calico")
      echo "Installing Calico CNI"
      install_calico "" "$(dirname "$CONFIG")"
      ;;

    "")
      # perfectly fine, we accepted the default KinD CNI
      ;;

    *)
      # we don't know what to do but we've got no CNI, return non-zero
      echo "${KUBERNETES_CNI} is not recognized. Supported options are \"calico\" or do not set the variable to use default."

ambient, you need to add `--set cni.ambient.enabled=true`. ### Calico For Calico, you must also modify the settings to allow source spoofing: - if deployed by operator, `kubectl patch felixconfigurations default --type='json' -p='[{"op": "add", "path": "/spec/workloadSourceSpoofi", "value": "Any"}]'` - if deployed by manifest, add env `FELIX_WORKLOADSOURCESPOOFI` with value `Any` in `spec.template.spec.containers.env` for daemonset `calico-node`. (This will allow PODs with specified annotation to skip...
