Istio Trait

The Istio trait allows configuring properties related to the Istio service mesh, such as sidecar injection and outbound IP ranges.

This trait is available in the following profiles: Kubernetes, Knative, OpenShift.

Configuration

Trait properties can be specified when running any integration with the CLI:

$ kamel run --trait istio.[key]=[value] --trait istio.[key2]=[value2] integration.groovy

The following configuration options are available:
