Note: each component can be installed in parallel with an existing Istio 1.0 or 1.1 installation in
`istio-system`. The new components will not interfere with existing apps, but can interoperate,
and it is possible to gradually move apps from Istio 1.0/1.1 to the new environments and
across environments ( for example canary -> prod )

    - "sidecar.istio.io/status" annotation is not present on the pod (created by injection of sidecar)
    - pod label "istio.io/dataplane-mode" is not "none"
- sidecar interception is enabled if:
    - "istio-init" container is not present in the pod.
    - istio-proxy container exists and
        - does not have DISABLE_ENVOY environment variable (which triggers proxyless mode)

Explicitly set values have highest priority, then profile settings, then chart defaults.

As an implementation detail of profiles, the default values for the chart are all nested under `defaults`.
When configuring the chart, you should not include this.
That is, `--set some.field=true` should be passed, not `--set defaults.some.field=true`.

### OpenShift

   set of functions like discovery, rich layer-7 routing, circuit breakers,
   policy enforcement and telemetry recording/reporting
   functions.
