The Kiali CR

Creating and updating the Kiali CR.

The Kiali Operator watches the Kiali Custom Resource (Kiali CR), a custom resource that contains the Kiali Server deployment configuration. Creating, updating, or removing a Kiali CR will trigger the Kiali Operator to install, update, or remove Kiali.

If you want the operator to re-process the Kiali CR (called “reconciliation”) without having to change the Kiali CR’s spec fields, you can modify any annotation on the Kiali CR itself. This will trigger the operator to reconcile the current state of the cluster with the desired state defined in the Kiali CR, modifying cluster resources if necessary to get them into their desired state. Here is an example illustrating how you can modify an annotation on a Kiali CR:

$ kubectl annotate kiali my-kiali -n istio-system --overwrite kiali.io/reconcile="$(date)"

The Operator provides comprehensive defaults for all properties of the Kiali CR. Hence, the minimal Kiali CR does not have a spec:

apiVersion: kiali.io/v1alpha1
kind: Kiali
metadata:
  name: kiali

Assuming you saved the previous YAML to a file named my-kiali-cr.yaml, and that you are installing Kiali in the same default namespace as Istio, create the resource with the following command:

$ kubectl apply -f my-kiali-cr.yaml -n istio-system

Often, but not always, Kiali is installed in the same namespace as Istio, thus the Kiali CR is also created in the Istio namespace.

Once created, the Kiali Operator should shortly be notified and will process the resource, performing the Kiali installation. You can wait for the Kiali Operator to finish the reconcilation by using the standard kubectl wait command and ask for it to wait for the Kiali CR to achieve the condition of Successful. For example:

kubectl wait --for=condition=Successful kiali kiali -n istio-system

You can check the installation progress by inspecting the status attribute of the created Kiali CR:

$ kubectl describe kiali kiali -n istio-system
Name:         kiali
Namespace:    istio-system
Labels:       <none>
Annotations:  <none>
API Version:  kiali.io/v1alpha1
Kind:         Kiali

  (...some output is removed...)

Never manually edit resources created by the Kiali Operator; only edit the Kiali CR.

You may want to check the example install page to see some examples where the Kiali CR has a spec and to better understand its structure. Most available attributes of the Kiali CR are described in the pages of the Installation and Configuration sections of the documentation. For a complete list, see the Kiali CR Reference.

It is important to understand the spec.deployment.cluster_wide_access setting in the CR. See the Namespace Management page for more information.

Once you created a Kiali CR, you can manage your Kiali installation by editing the resource using the usual Kubernetes tools:

$ kubectl edit kiali kiali -n istio-system

To confirm your Kiali CR is valid, you can utilize the Kiali CR validation tool.
