Collect container logs for restarted components in E2E tests
What type of PR is this?
/kind cleanup
- Added log collection functionality to check_component_restart function
- Automatically collect logs from previous container instances using kubectl logs -p when Karmada components are detected to have restarted
- Save collected logs to
$ARTIFACTS_PATHdirectory with filename format:${component_name}-${pod_name}-previous-logs.log
What this PR does / why we need it:
- Facilitate troubleshooting of component restart causes (OOM, panic, etc.)
- Provide more detailed debugging information to improve issue identification efficiency
- Collect logs alongside other E2E test artifacts for comprehensive test reporting
Which issue(s) this PR fixes:
Fixes #
Special notes for your reviewer:
- Log collection only occurs when component restarts are detected, no impact on normal test flow
- Added error handling to ensure log collection failures don't interrupt test execution
Does this PR introduce a user-facing change?:
NONE
Summary of Changes
Hello @XiShanYongYe-Chang, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request significantly enhances the debugging capabilities of E2E tests by introducing automatic log collection for restarted Karmada components. When a component restart is detected, the system now captures logs from the previous container instance, saving them as artifacts. This change aims to streamline troubleshooting of issues like OOM errors or panics, providing more comprehensive data for efficient problem identification and resolution, while ensuring no disruption to the standard test flow.
Highlights
- Enhanced E2E Test Debugging: Implemented automatic collection of previous container logs for restarted Karmada components during E2E tests.
- Log Collection Mechanism: Utilizes "kubectl logs -p" to retrieve logs from prior container instances, saving them to the "$ARTIFACTS_PATH" for analysis.
- Impact on Troubleshooting: Provides crucial debugging information for investigating component restarts (e.g., OOM, panic) without affecting normal test execution.
- Robustness: Includes error handling to ensure that failures during log collection do not interrupt the ongoing test execution.
