    Create Service Accounts for Cluster Authentication

    The CN-Series firewall requires three Service accounts with the minimum permissions that authorize it to communicate with your Kubernetes cluster resources. The service account (pan-plugin-user) created with the
    plugin-serviceaccount.yaml
     enables the Kubernetes plugin on Panorama to authenticate with the Kubernetes cluster for retrieving metadata on the pods.The other two yaml files,
    pan-mgmt-serviceaccount.yaml
    and
    pan-cni-serviceaccount.yaml
    , create the pan-mgmt-sa and the pan-cni-sa service accounts to enable the authentication between the fault tolerant CN-Mgmt pods, and between the CN-MGMT pod and the CN-NGFW pods.
    By default, the YAML files create the service account and the secret in the kube-system namespace; the Kubernetes plugin will only look for the secret in the kube-system namespace.
    To create the service accounts, your Kubernetes cluster should be ready.
    1. Run the service account YAML for the
      plugin-serviceaccount.yaml
      .
      This service account enables the permissions that Panorama requires to authenticate to the GKE cluster for retrieving Kubernetes labels and resource information. This service account is named pan-plugin-user by default.
      1. kubectl apply -f plugin-serviceaccount.yaml
      2. kubectl -n kube-system get secrets | grep pan-plugin-user-token
        To view the secrets associated with this service account.
      3. kubectl -n kube-system get secrets <secrets-from-above-command> -o json >> cred.json
        Create the credential file, named cred.json in this example, that includes the secrets and save this file. You need to upload this file to Panorama to set up the Kubernetes plugin for monitoring the clusters in Install the Kubernetes Plugin and Set up Panorama for CN-Series.
    2. Run the
      pan-mgmt-serviceaccount.yaml
       and
      pan-cni-serviceaccount.yaml
      .
      The
      pan-mgmt-serviceaccount.yaml
       creates a service account named pan-sa, and is required to enable the CN-MGMT and CN-NGFW Pods to communicate with each other, the PAN-CNI, and the Kubernetes API server. If you modify this service account name, you must also update the YAML files that you use to deploy the CN-MGMT and CN-NFGW Pods. The
      pan-cni-serviceaccount.yaml
       creates a service account named pan-cni-sa.
      kubectl apply -f pan-mgmt-serviceaccount.yaml
      kubectl apply -f pan-cni-serviceaccount.yaml
    3. Verify the service accounts.
      kubectl get serviceaccounts -n kube-system
