Hello @wuhuizuo, 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!

Summary of Changes

Hello! Gemini here, providing a summary of this pull request. This PR, authored by wuhuizuo, is titled "feat(dockerfiles/products): add OCI labels to Dockerfiles". Based on the title and the changes, the primary intent is to enhance the Dockerfiles for the ng-monitoring product by adding standard Open Container Initiative (OCI) image labels. This helps provide structured metadata about the image, such as its title, source repository, vendor, and license.

Highlights

• Add OCI Labels: The core change across all modified Dockerfiles is the addition of OCI standard LABEL instructions. These labels provide machine-readable metadata about the container image.
• Targeted Dockerfiles: The changes are applied to the Dockerfiles for the ng-monitoring product, specifically in the main directory and versioned subdirectories (lt6.5.12 and ~6.5.12).

Changelog

• dockerfiles/products/ng-monitoring/Dockerfile
  • Added OCI labels: org.opencontainers.image.title, org.opencontainers.image.source, org.opencontainers.image.vendor, and org.opencontainers.image.licenses.
• dockerfiles/products/ng-monitoring/lt6.5.12/Dockerfile
  • Added OCI labels: org.opencontainers.image.title, org.opencontainers.image.source, org.opencontainers.image.vendor, and org.opencontainers.image.licenses.
• dockerfiles/products/ng-monitoring/~6.5.12/Dockerfile
  • Added OCI labels: org.opencontainers.image.title, org.opencontainers.image.source, org.opencontainers.image.vendor, and org.opencontainers.image.licenses.

Code Review

The pull request successfully adds OCI image labels to the Dockerfiles for ng-monitoring. This is a good step towards improving image metadata and discoverability. The labels chosen (title, source, vendor, licenses) are standard and appropriate for the project.

Summary of Findings

• Duplication of OCI Labels: The OCI labels are duplicated across multiple Dockerfiles for the same product (ng-monitoring). This can lead to maintainability issues if the labels need to be updated in the future. While Dockerfiles don't have direct include mechanisms, exploring options like build arguments or build scripts could help centralize this information.

Merge Readiness

The code changes correctly add the specified OCI labels. The primary concern is the duplication of these labels across multiple Dockerfiles, which is a medium severity maintainability issue. I recommend addressing this duplication to improve future maintainability before merging. I am unable to approve the pull request; please have other reviewers review and approve this code before merging.

[gemini-code-assist]

These OCI labels are duplicated across the three ng-monitoring Dockerfiles (Dockerfile, lt6.5.12/Dockerfile, ~6.5.12/Dockerfile). While this is a simple change now, maintaining identical labels across multiple files can become cumbersome if they need to be updated in the future.

Consider if there's a way to define these common labels in a single place, perhaps using build arguments passed during the build process, or a script that generates the Dockerfiles. This would improve maintainability by adhering to the DRY (Don't Repeat Yourself) principle.
