How Do I Enable Namespace Injection for a Cluster?

When injecting a sidecar to the namespace of a cluster, if the namespace injection is not enabled in the cluster, perform the following steps:

  1. Connect to the cluster using kubectl.
  2. Run the kubectl get iop -nistio-system command to query iop resources.

    • If the following information is displayed, the iop resource exists. Go to 3.

    • If the following information is displayed, no iop resources exist. Go to 4.

  3. Run the kubectl edit iop -nistio-system data-plane command to modify the autoInject configuration item. In the preceding command, data-plane indicates the name of the iop resource queried in the previous step. Replace it with the actual value.

        global:
      defaultPodDisruptionBudget:
        enabled: true
      hub: *.*.*.*:20202/asm
      logging:
        level: default:info
      meshID: test-payment
      multiCluster:
        clusterName: test-yy
      network: test-yy-network
      proxy:
        autoInject: enabled
      remotePilotAddress: *.*.*.*
      tag: 1.8.6-r1-20220512225026

  4. Run the kubectl edit cm -nistio-system istio-sidecar-injector command to modify the istio-sidecar-injector configuration item.
