YellowDog 1.02 for Core

New Features and Improvements for Core

New Log Service

A new Log Service significantly enhances the task of administering and troubleshooting the core platform. This integrates with Grafana Loki to provide account-specific access to system logs, including both logs from Platform Services and logs from workers managed by the YellowDog Scheduler Service.

You can access this log information through the Platform Services Portal, where you can easily filter entries by entity ID, source service, and more.

All existing services have been updated to integrate with the new log format.

Compute Requirement Automatic Termination

Where a compute requirement has no running instances, it will be terminated by the YellowDog Platform.

This feature is intended to free up service resources, where these are unnecessarily allocated to compute requirements that have finished or stalled without properly terminating. A compute requirement will only be terminated if it has no instances, or if all its instances have been terminated, and if it has not changed status or claimed new instances for at least several hours.

YellowDog Scheduler Service Improvements

A number of improvements have been made to the YellowDog Scheduler Service. These include:

• If a Task Group is Starved of workers, but cannot claim more due to a worker claim behaviour of STARTUP_ONLY, its status will update to Failed.
• Communication between Scheduler and workers is now secured by generating a unique access key for each individual worker. The Yellowg Agent has been updated to support use of this key.
• The work requirement summary now provides information about when it was created, how many tasks it contains, how many of those tasks have been completed, and whether any tasks have failed.
• The Java client library auto-reconnects failed SSE stream connections.
• When configuring a compute requirement for a worker pool, pre-existing cloud-init information is not deleted.

Fixes for Core

• The Image Registry Service has been renamed to the Images Service.
• The Account Service’s error messages are now displayed correctly in the user interface.
