无法修补 Kiali configMap

Question

I have this Kiali configMap along with different Kiali resources like deployment, service etc all in a single yaml file

apiVersion: v1
kind: ConfigMap
metadata:
  name: kiali
  namespace: istio-system
  labels:
    helm.sh/chart: kiali-server-1.55.1
    app: kiali
    app.kubernetes.io/name: kiali
    app.kubernetes.io/instance: kiali
    version: "v1.55.1"
    app.kubernetes.io/version: "v1.55.1"
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/part-of: "kiali"
data:
  config.yaml: |
    external_services:
      custom_dashboards:
        enabled: true
      istio:
        root_namespace: istio-system

      openshift:

...

In this data I have to add this config under external-services

data:
  config.yaml: |
    external_services:  
      prometheus:
         url: "http://prometheus-prometheus.observability-prisma.svc:9090/"
      custom_dashboards:
        enabled: true
      istio:
        root_namespace: istio-system
        config_map_name: istio-1-15-3

I have tried using following kubectl patches but no one is working This patch is replacing the whole original data config part

kubectl patch configmap/kiali \                                                    
  -n istio-system \
  --type merge \
  -p '{"data":{"config.yaml":{"external_services":{"prometheus":{"url":"http://prometheus-prometheus.observability-prisma.svc:9090/"}}}}}'

This patch fails with the invalid request error. Since, the config under data is actually a string

kubectl patch cm kiali -n istio-system --type json --patch '[{ "op": "add", "path": "/data/config.yaml/external_services", "value": {"prometheus":{"url":"http://prometheus-prometheus.observability-prisma.svc:9090/"}} }]'

May I please get some assistance on how I can resolve this using kubectl or json-path function?

Answer 1

The Kiali operator stores its deployment configuration in Kiali CR(custom resource) , so if we create, update or remove a Kiali CR will trigger the Kiali operator to create, update or remove a Kiali. We cannot manually update a resource created by the Kiali operator, after you have created your Kiali CR you can manage your Kiali installation by using the below command

kubectl edit kiali kiali -n istio-system

Your Kiali CR can be validated by using the Kiali CR validation tool .
