0.72.0 / 2024-02-23

In this release we want to highlight the addition of ScrapeClasses.

ScrapeClasses is an experimental feature that allows declaring multiple scrape configurations in the Prometheus/PrometheusAgent objects that can be consumed by selected scrape-related resources, like ScrapeConfig, ServiceMonitor, PodMonitor and Probes. Initial support only allows the declaration of TLS configuration, but we plan to extend ScrapeClasses with more options in the future, e.g. Authorization, relabelings and scrape protocols.

0.66.0 / 2023-06-14

After research, we noticed how the default CPU requests of the config-reloader container were too high compared to the effective usage. We decided to decrease the default CPU requests from 100m to 10m. For most environments, this won't make a difference but if you need to increase the values, you can use the -config-reloader-cpu-request and -config-reloader-cpu-limit CLI arguments of the Prometheus operator.

0.65.0 / 2023-05-04

The main change introduced by this release is the new v1alpha1 ScrapeConfig CRD. This implements the proposal documented in #5279 and provides a Kubernetes native API to create and manage additional scrape configurations.

To try it, follow the following steps:

Install the new CRD in the cluster (see example/prometheus-operator-crd/monitoring.coreos.com_scrapeconfigs.yaml).
Update the Prometheus operator's RBAC permissions to manage ScrapeConfig resources (see example/rbac/prometheus-operator/prometheus-operator-cluster-role.yaml).

NOTE: if these conditions aren't met, the operator will start but it won't be able to reconcile the ScrapeConfig resources.

[FEATURE] Add the status subresource for the ThanosRuler CRD. #5520
[FEATURE] Add spec.web.timeout and spec.web.getConcurrency to the Alertmanager CRD. #5478
[FEATURE] Add spec.groups[].limit to the Prometheus CRD. #4999

[ENHANCEMENT] Add optional liveness and readiness probes to prometheus-config-reloader. This can be enabled via the --enable-config-reloader-probes CLI flag. #5449
[BUGFIX] Don't start the PrometheusAgent controller if the CRD isn't present or the operator lacks permissions. #5476
[BUGFIX] Declare spec.rules optional in PrometheusRule CRD. #5481
[BUGFIX] Fix incorrect metric counter value for failed sync status. #5533

0.64.1 / 2023-04-24

[BUGFIX] Fix panic when scraping /metrics with PrometheusAgent resources declared. #5511

0.64.0 / 2023-03-29

This release provides first-class support for running Prometheus in agent mode with the new PrometheusAgent CRD. As the v1alpha1 version tells it, we don't recommend using it in production but we're eager to hear all possible feedback.

To try it, follow the following steps:

Install the new CRD in the cluster (see example/prometheus-operator-crd/monitoring.coreos.com_prometheusagents.yaml).
Update the Prometheus operator's RBAC permissions to manage PrometheusAgents resources (see example/rbac/prometheus-operator/prometheus-operator-cluster-role.yaml).

NOTE: if these conditions aren't met, the operator will start but it won't be able to reconcile the PrometheusAgent resources.

For the first time, the container images associated to this release are signed using sigstore.

0.57.0 / 2022-06-02

The main change introduced by this release is a new v1beta1 API version for the AlertmanagerConfig CRD.

Changes compared to the v1alpha1 API:

Renamed spec.muteTimeIntervals field to to spec.timeIntervals.
Removed regex field from the Matcher type.
Replaced all v1.SecretKeySelector types by the SecretKeySelector type
- Removed optional field.
- name and key fields are required.

As a pre-requisite, you need to deploy the admission webhook and configure the conversion webhook in the AlertmanagerConfig CRD object so that users can use both v1alpha1 and v1beta1 versions at the same time. There are more details in Documentation/user-guides/webhook.md about the webhook configuration.

Because of the conversion webhook requirement, the new version is an opt-in feature: the bundle.yaml file and the manifests from example/prometheus-operator-crd don't deploy the new API version (the manifests to enable the v1beta1 version are under the example/prometheus-operator-crd-full directory). We will wait until v0.59.0 (at least) before enabling the new API version by default.

[CHANGE] Added validations at the API level for the time-based fields of the ThanosRuler CRD. #4815
[CHANGE] Added validations at the API level for the OpsGenie's responders field of the AlertmanagerConfig CRD. #4725

[BUGFIX] Fixed errors for Alertmanager configurations using the new entity, actions and opsgenie_api_key_file fields. #4797

[FEATURE] Added status subresource to the Prometheus CRD. #4580
[ENHANCEMENT] Added excludedFromEnforce field to the Prometheus CRD. It allows to define PodMonitor, ServiceMonitor, Probe or PrometheusRule objects for which the namespace label enforcement (if enabled) should not be applied.

When the path contains a full path, a volume + volume mount should be explicitly given in the Prometheus spec since the root file system is now read-only. #4566
[CHANGE/BUGFIX] Added skip TLS verify for the config-reloader HTTP client when informing Prometheus/Alertmanager on a config reload (partial fix for #4273). #4592

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: https://github.com/coreos/prometheus-operator/pull/1984#issue-221139702

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>

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.

[FEATURE] Allow configuring Prometheus and Alertmanager servers to listen on loopback interface, allowing proxies to be the ingress point of those Pods.
[FEATURE] Allow configuring additional containers in Prometheus and Alertmanager Pods.
