(camel-k) branch main updated: feat(trait): Add metricType support to the KEDA trait triggers
This is an automated email from the ASF dual-hosted git repository.
squakez pushed a commit to branch main
in repository https://gitbox.apache.org/repos/asf/camel-k.git
The following commit(s) were added to refs/heads/main by this push:
new 2dd450478 feat(trait): Add metricType support to the KEDA trait triggers
2dd450478 is described below
commit 2dd450478bc3be72f6639d281c3ca959709383e9
Author: Wojciech_Grazawski <Wo...@ah.nl>
AuthorDate: Wed Aug 5 09:53:01 2026 +0200
feat(trait): Add metricType support to the KEDA trait triggers
Add an optional trigger-level `metricType` field to the KEDA trait
(`Utilization`, `AverageValue` or `Value`), mapping to KEDA's
ScaleTriggers.metricType. Required by the cpu/memory scalers in KEDA
v2.18+ where the deprecated metadata.type was removed.
Regenerated CRDs, Helm CRDs and API docs.
