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.

• [CHANGE] Decrease the default CPU requests for the config-reloader container from 100m to 10m. #5539
• [FEATURE] Add spec.alertmanagerConfiguration.global.PagerdutyURL to the Alertmanager CRD. #5469
• [FEATURE] Add spec.volumeMounts to the ThanosRuler CRD. #5541

0.65.2 / 2023-05-31

0.65.1 / 2023-05-05

• [BUGFIX] Fix panic when ScrapeConfig CRD is not installed. #5550

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:

1. Install the new CRD in the cluster (see example/prometheus-operator-crd/monitoring.coreos.com_scrapeconfigs.yaml).
2. 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
• [FEATURE] Add ScrapeConfig CRD. #5335
• [ENHANCEMENT] Set a default for seccompProfile on the operator and webhook Deployments to RuntimeDefault. #5477
• [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:

1. Install the new CRD in the cluster (see
   example/prometheus-operator-crd/monitoring.coreos.com_prometheusagents.yaml).
2. 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.

• [CHANGE] Remove the /apis endpoints from the operator's web server. #5396
• [CHANGE] Set default default value of spec.portName to web. #5350
• [FEATURE] Add v1alpha1 PrometheusAgent CRD to run Prometheus in agent mode. #5385
• [FEATURE] Add --reload-timeout argument to the config-reloader binary which controls how long the program will wait for the reload operation to complete (default: 30s). #5349
• [ENHANCEMENT] Set web server's ReadTimeout and ReadHeaderTimeout to 30s for Prometheus operator and config-reloader to avoid potential slowloris attacks. #5340
• [ENHANCEMENT] Add support for DropEqual and KeepEqual relabeling actions. #5368
• [ENHANCEMENT] Drop invalid PrometheusRule objects instead of failing the reconciliation of Prometheus and ThanosRuler objects. #5221
• [ENHANCEMENT] Add spec.thanos.blockSize field to the Prometheus CRD. #5360
• [ENHANCEMENT] Add spec.thanos.configTimeout and spec.thanos.configInterval to the Prometheus CRD. #5399

• [ENHANCEMENT] Add spec.alertmanagerConfiguration.global.opsGenieApiUrl and spec.alertmanagerConfiguration.global.opsGenieApiKey fields to the Alertmanager CRD. #5422
• [ENHANCEMENT] Reduce the operator's memory usage by using metadata informers for Kubernetes secrets and configmaps. #5424 #5448
• [BUGFIX] Add init-config-reloader init container to avoid a restart of the Alertmanager's config-reloader container when the pod starts. #5358
