- Ability for pod to be Completed, unlike in Statefulset - eg. if 3 pods are running and first one finishes, all 3 must be running until all 3 are done. With this setup, the first finished pod can remain in Completed state.
- Fixed shutdown order - crawler pods now correctly shutdown first before redis pods, by switching to background deletion.
- Pod priority decreases with scale: 1st instance of a new crawl can preempt 3rd or 2nd instance of another crawl
- Create priority classes upto 'max_crawl_scale, configured in values.yaml
- Improved scale change reconciliation: if increasing scale, immediately scale up. If decreasing scale,
graceful stop scaled-down instance to complete via redis 'stopone' key, wait until they exit with Completed state
before adjust status.scale / removing scaled down pods. Ensures unaccepted interrupts don't cause scaled down data to be deleted.
- Redis pod remains inactive until crawler is first active, or after no crawl pods are active for 60 seconds
- Configurable Redis storage with 'redis_storage' value, set to 3Gi by default
- CrawlJob deletion starts as soon as post-finish crawl operations are run
- Post-crawl operations get their own redis instance, since one during response is being cleaned up in finalizer
- Finalizer ignores request with incorrect state (returns 400 if reported as not finished while crawl is finished)
- Current resource usage added to status
- Profile browser: also manage single pod directly without statefulset for consistency.
- Restart pods via restartTime value: if spec.restartTime != status.restartTime, clear out pods and update status.restartTime (using OnDelete policy to avoid recreate loops in edge cases).
- Update to latest metacontroller (v4.11.0)
- Add --restartOnError flag for crawler (for browsertrix-crawler 0.11.0)
- Failed crawl logging: dd 'fail_crawl()' to be used for failing a crawl, which prints logs for default container (if enabled) as well as pod status
- tests: check other finished states to avoid stuck in infinite loop if crawl fails
- tests: disable disk utilization check, which adds unpredictability to crawl testing!
