helm show values istio/gateway
```
### Profiles
Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.
These can be set with `--set profile=<profile>`.
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.
For consistency, the same profiles are used across each chart, even if they do not impact a given chart.
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
When deploying the gateway in an OpenShift cluster, use the `openshift` profile to override the default values, for example:
```console
helm install istio-ingressgateway istio/gateway -- set profile=openshift
```
### `image: auto` Information
The image used by the chart, `auto`, may be unintuitive.

{{/*
Complex logic ahead...
We have three sets of values, in order of precedence (last wins):
1. The builtin values.yaml defaults
2. The profile the user selects
3. Users input (-f or --set)
Unfortunately, Helm provides us (1) and (3) together (as .Values), making it hard to insert (2).
However, we can workaround this by placing all of (1) under a specific key (.Values.defaults).
We can then merge the profile onto the defaults, then the user settings onto that.
Finally, we can set all of that under .Values so the chart behaves without awareness.
