Installation in `kube-system` is recommended to ensure the [`system-node-critical`](https://kubernetes.io/docs/tasks/administer-cluster/guaranteed-scheduling-critical-addon-pods/)

`priorityClassName` can be used. You can install in other namespace only on K8S clusters that allow

'system-node-critical' outside of kube-system.

## Configuration
28
+
29
+
To view support configuration options and documentation, run:
30
+
31
+
```console
32
+
helm show values istio/istio-cni
33
+
```
34
+
35
+
### Profiles
36
+
37
+
Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.
38
+
These can be set with `--set profile=<profile>`.
39
+
For example, the `demo` profile offers a preset configuration to try out Istio in a test environment, with additional features enabled and lowered resource requirements.
40
+
41
+
For consistency, the same profiles are used across each chart, even if they do not impact a given chart.
42
+
43
+
Explicitly set values have highest priority, then profile settings, then chart defaults.
44
+
45
+
As an implementation detail of profiles, the default values for the chart are all nested under `defaults`.
46
+
When configuring the chart, you should not include this.
47
+
That is, `--set some.field=true` should be passed, not `--set defaults.some.field=true`.
48
+
49
+
### Ambient
50
+
51
+
To enable ambient, you can use the ambient profile: `--set profile=ambient`.
52
+
53
+
#### Calico
54
+
55
+
For Calico, you must also modify the settings to allow source spoofing:
56
+
57
+
- if deployed by operator, `kubectl patch felixconfigurations default --type='json' -p='[{"op": "add", "path": "/spec/workloadSourceSpoofing", "value": "Any"}]'`
58
+
- 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. )
59
+

+
### GKE notes
61
+
62
+
On GKE, 'kube-system' is required.
63
+
64
+
If using `helm template`, `--set cni.cniBinDir=/home/kubernetes/bin` is required - with `helm install`
