Summary of Changes
Hello @oilbeater, 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 significantly improves the reliability of the Kube-OVN installation process by introducing a pre-flight validation. It prevents silent failures or misconfigurations by ensuring that the required master nodes, identified by their labels, are present before proceeding with the deployment, thus providing immediate feedback to the user if a prerequisite is not met.
Highlights
- Installation Robustness: I've added a critical check within the Helm helper templates (
_helpers.tpl) for bothkube-ovnandkube-ovn-v2charts. This check ensures that if no nodes are found with theMASTER_NODES_LABELduring installation, the Helm deployment will now explicitly fail with a descriptive error message. - Improved Error Messaging: The new failure message clearly indicates that no nodes were found with the specified label and advises the user to verify their
MASTER_NODES_LABELconfiguration or ensure master nodes are correctly labeled.

Code Review
This pull request adds a helpful check to fail the Helm installation if no master nodes are found using the configured labels. The implementation has issues in both charts related to the placement of the check, and an incorrect error message in the kube-ovn-v2 chart. I've left comments with suggestions to address these issues to ensure the feature works as intended and provides clear feedback to users.
