Summary of Changes

Hello @MahaoAlex, 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 introduces a streamlined and automated workflow for generating and packaging Helm charts. By adding a new Makefile target and a dedicated script, the process of preparing charts for release is standardized, ensuring consistent versioning and simplifying distribution for other developers.

Highlights

• New Helm Chart Generation Target: A new generate-charts target has been added to the Makefile to automate the process of generating and packaging Helm charts.
• Automated Helm Chart Script: A new shell script, hack/generate-charts.sh, has been introduced. This script handles the installation of the Helm CLI, copying of base charts, dynamic updating of version tags, and packaging of the final Helm chart.
• Dynamic Versioning: The chart generation process now dynamically updates image tags and chart versions within values.yaml and Chart.yaml based on environment variables (AGENTCUBE_CHART_VERSION and AGENTCUBE_IMAGE_TAG), ensuring consistent versioning for releases.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request introduces a new Makefile target and a shell script to automate the generation and packaging of Helm charts. This is a valuable addition for distributing the application. The script is well-structured, but I've identified a few issues related to script robustness and correctness. My review includes suggestions to improve temporary directory handling to prevent potential errors, and to fix and simplify the logic for updating chart metadata, which is currently incorrect and redundant. Addressing these points will make the script more reliable and maintainable.

Hi @hzxuzhonghu ,

I've submitted this PR to automate the Helm Chart releases, and to make it fully functional, I would really appreciate your help with a small configuration step:

Could you please help add a repository secret? It would be wonderful if you could:

1. Create a Fine-grained PAT: With 'Contents: Read & Write' permissions for the volcano-sh/helm-charts repository.
2. Set up the Secret:

• Name: HELM_CHARTER_TOKEN
• Value: The token created above.

TIA!
