When you install the Prometheus operator, the new Custom Resource Definition or CRD gets created. NOTE: Kubernetes 1.10+ with Beta APIs and Helm 2.10+ are required! Installing Prometheus operator and Prometheus with all dependencies is just one command now: ⚡ helm install \ # Depending on which DNS solution you have installed in your cluster enable the right exporter I prepared a custom values file to use for installation with Helm: ⚡ cat > custom-values.yaml <
For example, if you have a frontend app which exposes Prometheus metrics on port web, you can create a service monitor which will configure the Prometheus server automatically: apiVersion: /v1 It instructs Prometheus to watch on a new target. Here is the official operator workflow and relationships view:įrom the picture above you can see that you can create a ServiceMonitor resource which will scrape the Prometheus metrics from the defined set of pods. In my opinion, operators are the best way to deploy stateful applications on Kubernetes.ĬoreOS team also created Prometheus operator for deploying Prometheus on top of Kubernetes. I wrote about Elasticsearch operator and how operator works a few months ago so you might check it out. Prometheus OperatorĬoreOS introduced operators as business logic in the first place.

In this post, I will show you how to get the Prometheus running and start monitoring your Kubernetes cluster in 5 minutes. You need a proper monitoring solution, and because the Prometheus is CNCF project as Kubernetes, it is probably the best fit. Kubernetes being a distributed system is not easy to troubleshoot. However, when you start to use it and deploy some applications, you might expect some issues over time. To have a Kubernetes cluster up and running is pretty easy these days.
