0.43.0 / 2020-10-26

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

0.24.0 / 2018-10-11

This release has a breaking changes for prometheus_operator_.* metrics.

prometheus_operator_alertmanager_reconcile_errors_total and prometheus_operator_prometheus_reconcile_errors_total are now combined and called prometheus_operator_reconcile_errors_total. Instead the metric has a "controller" label which indicates the errors from the Prometheus or Alertmanager controller.

The same happened with prometheus_operator_alertmanager_spec_replicas and prometheus_operator_prometheus_spec_replicas which is now called prometheus_operator_spec_replicas and also has the "controller" label.

The prometheus_operator_triggered_total metric now has a "controller" label as well and finally instruments the Alertmanager controller.

For a full description see: prometheus-operator#1984 (comment)

In order to support multiple namespaces, the --namespace flag changed to --namespaces and accepts and comma-separated list of namespaces as a string.

0.20.0 / 2018-06-05

With this release we introduce a new Custom Resource Definition - the PrometheusRule CRD. It addresses the need for rule syntax validation and rule selection across namespaces. PrometheusRule replaces the configuration of Prometheus rules via K8s ConfigMaps. There are two migration paths:

Automated live migration: If the Prometheus Operator finds Kubernetes ConfigMaps that match the RuleSelector in a Prometheus specification, it will convert them to matching PrometheusRule resources.
Manual migration: We provide a basic CLI tool to convert Kubernetes ConfigMaps to PrometheusRule resources.

go get -u github.com/coreos/prometheus-operator/cmd/po-rule-migration

--rule-config-map=<path-to-config-map> \
--rule-crds-destination=<path-to-rule-crd-destination>

[BUGFIX] Fix alertmanager >=0.15.0 cluster gossip communication (#1193)

0.18.0 / 2018-03-04

From this release onwards only Kubernetes versions v1.8 and higher are supported. If you have an older version of Kubernetes and the Prometheus Operator running, we recommend upgrading Kubernetes first and then the Prometheus Operator.

While multiple validation issues have been fixed, it will remain a beta feature in this release. If you want to update validations, you need to either apply the CustomResourceDefinitions located in example/prometheus-operator-crd or delete all CRDs and restart the Prometheus Operator.

Some changes cause Prometheus and Alertmanager clusters to be redeployed. If you do not have persistent storage backing your data, this means you will loose the amount of data equal to your retention time.

[CHANGE] Use canonical /prometheus and /alertmanager as data dirs in containers.
[FEATURE] Allow configuring Prometheus and Alertmanager servers to listen on loopback interface, allowing proxies to be the ingress point of those Pods.
