`foo=bar,istio=ingressgateway`:

```yaml
name: my-custom-gateway # Override the name to match existing resources
labels:
  app: "" # Unset default app selector label
  istio: ingressgateway # override default istio selector label
  foo: bar # Add the existing custom selector label
```

#### Migrating an existing Helm release

## Sidecar Mode Implementation Details

Istio CNI injection is currently based on the same Pod annotations used in init-container/inject mode.

### Selection API

- plugin config "exclude namespaces" applies first
- ambient is enabled if:
    - namespace label "istio.io/dataplane-mode" == "ambient", and/or pod label "istio.io/dataplane-mode" == "ambient"

  - Select `Manually`.
  - Give it a name. The name will be displayed on TeamCity web UI. We highly recommend it be capitalized from the branch name, i.e. `MyTestBranch`.
  - The project ID will be auto-generated as `Gradle_MyTestBranch`. If not, you probably selected wrong parent, the "Parent project" should be `Gradle`.
