Summary of Changes

Hello @zhangzujian, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the Role-Based Access Control (RBAC) configurations within Kube-OVN by moving away from broad wildcard permissions. It explicitly defines the allowed actions for specific resources, enhancing security and clarity in access management.

Highlights

• RBAC Verb Specificity: Replaced the wildcard "*" verb with an explicit list of allowed verbs (create, get, list, update, patch, watch, delete) for qos-policies and qos-policies/status resources in RBAC configurations.
• Lease Resource Permissions: Updated the RBAC rules for leases resources, replacing the wildcard verb with a specific list (create, update, patch, get, watch) and adding a resourceNames constraint to kube-ovn-controller.

Code Review

This pull request improves the security of Kube-OVN by adhering to the principle of least privilege in its RBAC configuration. The changes replace wildcard verb permissions with an explicit list of required verbs for various resources. A significant improvement is scoping the permissions for leader election leases to a specific resource name, which greatly reduces the potential attack surface. These changes are applied consistently across both Helm chart versions and the installation script. The implementation is correct and enhances the overall security posture of the project.
