prometheus-operator/prometheus-operator v0.43.0

0.43.0 / 2020-10-26

on GitHub

This release introduces a new AlertmanagerConfig CRD that allows to split the Alertmanager configuration in different objects. For now the CRD only supports the PagerDuty, OpsGenie and webhook receivers, other integrations will follow in future releases of the operator. The current version of the CRD is v1alpha1 meaning that testing/feedback is encouraged and welcome but the feature is not yet considered stable and the API is subject to change in the future.

• [CHANGE] Use a single reloader sidecar (instead of 2) for Prometheus. The --config-reloader-image flag is deprecated and will be removed in a future release (not before v0.45.0). Make sure to start the operator with a version of --prometheus-config-reloader that is at least v0.43.0 otherwise the Prometheus pods will fail to start. #3457
