Configuration: Check Scheduling¶
This page describes how check intervals and parallelism work.
Resource Type Defaults¶
| Resource Type | Default Interval | Default Parallelism |
|---|---|---|
| HTTP | 1 minute | 5 threads |
| DOCKER | 3600 minutes (60 h) | 2 threads |
| DOCKERREPOSITORY | 60 minutes | 1 thread |
Settings are managed in Admin -> Resource Types.
How Scheduler Timing Works¶
- The scheduler loop runs every 30 seconds.
- A resource type run is dispatched when
now - lastRun >= interval. - Parallelism controls concurrent checks for that type.
Startup Behavior¶
Kairos always performs an immediate check pass at startup, independent of configured intervals.
DOCKERREPOSITORY Behavior¶
DOCKERREPOSITORY runs do not create direct check entries.
Instead, each run synchronizes discovered images into generated DOCKER resources in an auto-created group and removes resources that no longer exist in the upstream registry.
