Summary of Changes

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!

This pull request streamlines and modernizes the CI/CD pipeline infrastructure by standardizing artifact management. It introduces a common utility container for various test environments and transitions the artifact download process to leverage OCI (Open Container Initiative) artifacts. This refactoring aims to improve the consistency, reliability, and potentially the performance of pipeline executions by centralizing utility functions and adopting a more robust artifact distribution method.

Highlights

• Introduction of a utils container: A new utils container, sourced from ghcr.io/pingcap-qe/cd/utils/release:v2025.10.12-7-gfdd779c, has been added to numerous Kubernetes pod templates across various release branches (6.2, 6.5, 8.2, 8.3, 8.4, and 9.0-beta) and test types. This container is configured with specific CPU and memory resources.
• Migration to OCI Artifact Download: Jenkins Groovy pipeline scripts for jdbc, mysql, nodejs, and python_orm integration tests in the release-9.0-beta branch have been updated. This involves defining OCI artifact tags (OCI_TAG_PD, OCI_TAG_TIKV), switching the artifact host from FILE_SERVER_URL to OCI_ARTIFACT_HOST (hub-zot.pingcap.net/mirrors/hub), and utilizing a new script (download_pingcap_oci_artifact.sh) within the newly introduced utils container for downloading TiDB components.

Code Review

This pull request refactors the CI pipelines to download Pingcap OCI artifacts using a new utils container and a dedicated script. This is a good improvement that centralizes the artifact download logic. However, I've found a critical issue in several of the pod template YAML files where the new utils container is defined twice. This will cause the Kubernetes pods to fail to be created and will break the corresponding pipelines. Please see the detailed comments for the specific files that need to be fixed.
