Cómo habilitar el registro de Istio

Para depurar Istio, es necesario habilitar el registro. Para ello, realiza los siguientes pasos:

1. Edit the istio configmap in istio-system namespace, by using the following command:

   kubectl edit cm -n istio-system istio

2. Under data.mesh, add the following fields:

   accessLogFile: /dev/stdout
   logLevel: debug

   The following sample is an example of an updated istio configmap:

   apiVersion: v1
   data:
     mesh: |-
       accessLogFile: /dev/stdout
       logLevel: debug
       defaultConfig:
         discoveryAddress: istiod.istio-system.svc:15012
         image:
           imageType: distroless
         proxyMetadata:
           WASM_INSECURE_REGISTRIES: '*'
       defaultProviders:
         metrics:
         - prometheus
       enablePrometheusMerge: true
       extensionProviders:
       - envoyExtAuthzHttp:
           includeHeadersInCheck:
           - authorization
           - cookie
           port: 80
           service: auth-oauth2-proxy.uipath.svc.cluster.local
         name: oauth2-proxy
       rootNamespace: istio-system
       trustDomain: cluster.local
     meshNetworks: 'networks: {}'
   kind: ConfigMap
   metadata:
     annotations:
       meta.helm.sh/release-name: istiod
       meta.helm.sh/release-namespace: istio-system
     labels:
       app.kubernetes.io/managed-by: Helm
       install.operator.istio.io/owning-resource: unknown
       istio.io/rev: default
       operator.istio.io/component: Pilot
       release: istiod
     name: istio
     namespace: istio-system
     resourceVersion: "180392"
     uid: 30647d4d-f62a-477e-ad80-c98a93f48855

3. Restart the istio deployments, by using the following commands:

   kubectl rollout restart deploy/istiod -n istio-system
   kubectl rollout restart ds/istio-ingressgateway -n istio-system
