Integrate Thanos with Kurator

This task shows how to integrate multi-cluster monitoring with Kurator.

What is Thanos

Thanos provides a global query view, high availability, data backup with historical, cheap data access as its core features in a single binary.

In this task, we will show you how to install Thanos with kurator.

Prerequisites

This task requires you have installed karmada and have joined at least one member cluster. Otherwise, setup karmada environment following Install Karmada with Kurator.

Install Thanos

Kurator provides a very simple command to install Thanos and add karmada-apiserver as the destination to deploy application to.

  • --kubeconfig and --context specifies the cluster where Karmada Apiserver, Kurator use Karmada to orchestrate Thanos application.
  • --host-kubeconfig and --host-context specifies the cluster where to deploy Thanos itself, it is the host cluster that hold Thanos.
  • --object-store-config specifies the object store configuration used by Thanos, more details can be found here.
kurator install thanos --host-kubeconfig /root/.kube/kurator-host.config --host-context kurator-host --object-store-config /root/thanos/thanos-config.yaml

Verify Thanos query

Suppose you are running the installation in an external VM, you need to expose Thanos server.

kubectl port-forward --address 0.0.0.0 svc/thanos-query -n thanos 9090:9090 --kubeconfig /root/.kube/kurator-host.config --context kurator-host

And then access Thanos server https://<your vm address>:9090/stores from your browser.
