• For application monitoring, a separate Prometheus operator is required. Careful planning must be taken into consideration to avoid the situation where the two managers (operators) are managing the exact same resources (CRD). Though I am using OpenShift as the cluster, the general steps apply to other Kubernetes implementations.

    • The Prometheus Operator creates, configures and manages a prometheus cluster. The Prometheus operator manages 3 customer resource definitions namely: Prometheus: The Prometheus CRD defines a Prometheus setup to be run on a Kubernetes cluster. The Operator creates a Statefulset for each definition of the Prometheus resource.
    • For example: if a prometheus CRD like the one below is present in the cluster, the prometheus-operator controller would create a matching deployment of Prometheus into the kubernetes cluster, that in this case would also link up with the alertmanager by that name in the monitoring namespace.

    • Sep 21, 2020 · Prometheus Operator operates Prometheus and optionally ThanosRuler components. Other Thanos components, such as the querier and store gateway, must be configured separately. The Thanos system integrates with Prometheus by adding a Thanos sidecar to each Prometheus instance. The Thanos sidecar can be configured directly in the Prometheus CRD.
    • The prometheus operator provides the easy way to deploy configure and monitor your prometheus instances on kubernetes cluster. To do so, prometheus operator introduces three types of custom resource definition(CRD) in kubernetes. Prometheus; Alertmanager; ServiceMonitor

    • Custom resources are extensions of the Kubernetes API. This page discusses when to add a custom resource to your Kubernetes cluster and when to use a standalone service. It describes the two methods for adding custom resources and how to choose between them. Custom resources A resource is an endpoint in the Kubernetes API that stores a collection of API objects of a certain kind; for example ...
    • Prometheus operator watches for Prometheus crd. Once a Prometheus crd is created, Prometheus operator generates respective configuration and creates a StatefulSet to run Prometheus server.

    • Mar 15, 2019 · Red Hat, in collaboration with Microsoft, Google Cloud, and Amazon Web Services, recently launched OperatorHub.io. OperatorHub.io is designed as a public registry for finding services backed by Kubern
    • The Prometheus Operator uses CRD’s as they are introduced as new resources into the cluster to perform operations such as adding service monitors for new types of applications, to configure rules to run against metrics collected from service monitors, or to configure alerts to send to the Prometheus Alert Manager.

    • Jul 25, 2019 · CoreOs launched Prometheus operator to ease the process of integrating K8s with Prometheus. It preserves the configuration of both the K8s and Prometheus while installing and configuring the cluster. It provides easy monitoring for K8s services and deployments, along with managing Prometheus, Grafana and Alertmanager configuration.

    • The Operator automatically generates Prometheus scrape configuration based on the definition. Alertmanager , which defines a desired Alertmanager deployment. The first stage is to deploy the service account and RBAC rules required for your instance of Prometheus to allow it to pull metrics from the pods in the name space.
