Modify the Rancher Cluster Options YAML File

1. Using the admin credentials that you created previously, log in to the Rancher portal.
2. Click the Navigation Menu and select Cluster Management.
3. Locate the cluster to be modified, click the vertical ellipses menu, and then select Edit Config.
4. Click Edit as YAML.

   For different versions of Rancher, see Rancher documentation.
5. Add the following lines under the Services section in the existing YAML file.

   kube-controller:
    extra_args: 
         cluster-signing-cert-file: "/etc/kubernetes/ssl/kube-ca.pem"
         cluster-signing-key-file: "/etc/kubernetes/ssl/kube-ca-key.pem"

   kubelet:
    extra_binds: 
       - ’/mnt:/mnt:rshared’
       - '/var/log/pan-appinfo:/var/log/pan-appinfo’

   If you are using a storage path other than '/mnt', you should ensure that you modify the storage path under the extra_binds.

6. Click Save and wait until cluster upgrading becomes active before deploying the CN-Series firewall.
