Modifying Cluster Agent Installation Information

Scenario

• You need to modify the scope of cluster nodes where the agent is to be installed. After the modification, the agent on all cluster nodes will be automatically uninstalled, and then the agent will be reinstalled on specified nodes.
• The container runtime type and sock address need to be modified. After the modification, the agent on all cluster nodes will be automatically uninstalled, and then the agent will be reinstalled on specified nodes.
• Automatic agent upgrade needs to be enabled or disabled.

Modifying Access Information

1. Log in to the management console.
2. Click in the upper left corner of the page, select a region, and choose Security > Host Security Service. The HSS page is displayed.

   Table 1 Modifiable access parameters

   Parameter	Description
   Configuration Rules	Select an agent configuration rule. Default Rule: Select this if the sock address of container runtime is a common address. The agent will be installed on nodes having no taints. Custom: Select this rule if the sock address of your container runtime is not a common address or needs to be modified, or if you only want to install the agent on specific nodes. NOTE: If the sock address of your container runtime is incorrect, some HSS functions may be unavailable after the cluster is connected to HSS. You are advised to select all runtime types.
   (Optional) Advanced Configuration	This parameter can be set if Custom is selected for Configuration Rules. Click to expand all advanced configuration items. Enabling auto upgrade agent Configure whether to enable automatic agent upgrade. If it is enabled, HSS automatically upgrades the agent to the latest version between 00:00 to 06:00 every day to provide you with better services. Node Selector Configuration Select the tag of the nodes where the agent is to be installed. If this parameter is not specified, the agent will be installed on all nodes having no taints by default. Tolerance Configuration If the taint tag is selected in Node Selector Configuration and the agent needs to be installed on the taint node, you can configure taint toleration.

7. Click Complete.

   If the container runtime type, container runtime sock address, node selection configuration, or tolerance configuration is modified, the agent on all cluster nodes will be automatically uninstalled and then reinstalled. Wait until the agent installation is complete.
