  • [CHANGE] Deprecate specification of Prometheus rules via ConfigMaps in favor of PrometheusRule CRDs

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 accross namespaces. PrometheusRule replaces the configuration of Prometheus rules via K8s ConfigMaps. There are two migration paths:

  1. 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.

  2. 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
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.
  • [FEATURE] Allow configuring additional containers in Prometheus and Alertmanager Pods.
  • [FEATURE] Add ability to whitelist Kubernetes labels to become Prometheus labels.
  • [FEATURE] Allow specifying additonal secrets for Alertmanager Pods to mount.
  • [FEATURE] Allow specifying bearer_token_file for Alertmanger configurations of Prometheus objects in order to authenticate with Alertmanager.
  • [FEATURE] Allow specifying TLS configuration for Alertmanger configurations of Prometheus objects.
  • [FEATURE] Add metrics for reconciliation errors: prometheus_operator_alertmanager_reconcile_errors_total and prometheus_operator_prometheus_reconcile_errors_total.
  • [FEATURE] Support read_recent and required_matchers fields for remote read configurations.
  • [FEATURE] Allow disabling any defaults of SecurityContext fields of Pods.
  • [BUGFIX] Handle Alertmanager >=v0.15.0 breaking changes correctly.
  • [BUGFIX] Fix invalid validations for metric relabeling fields.
  • [BUGFIX] Fix validations for AlertingSpec.
  • [BUGFIX] Fix validations for deprecated storage fields.
  • [BUGFIX] Fix remote read and write basic auth support.
  • [BUGFIX] Fix properly propagate errors of Prometheus config reloader.

0.17.0 / 2018-02-15
