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.yaml

The following configuration options are available:

Property Type Description

Property	Type	Description
`istio.enabled`	`bool`	Can be used to enable or disable a trait. All traits share this common property.
`istio.allow`	`string`	Configures a (comma-separated) list of CIDR subnets that should not be intercepted by the Istio proxy (`10.0.0.0/8,172.16.0.0/12,192.168.0.0/16` by default).
`istio.inject`	`bool`	Forces the value for labels `sidecar.istio.io/inject`. By default the label is set to `true` on deployment and not set on Knative Service.

istio.enabled

bool

Can be used to enable or disable a trait. All traits share this common property.

istio.allow

string

Configures a (comma-separated) list of CIDR subnets that should not be intercepted by the Istio proxy (10.0.0.0/8,172.16.0.0/12,192.168.0.0/16 by default).

istio.inject

bool

Forces the value for labels sidecar.istio.io/inject. By default the label is set to true on deployment and not set on Knative Service.

the variables names are "snake case" if you’re using in kamel CLI, for example trait.myParam has to be translated as -t trait.my-param
