- 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! fixes #1147 --------- Co-authored-by: Tessa Walsh <tessa@bitarchivist.net>
