Single Cluster installation

To install the Thanos operator on a single cluster, complete the following steps.

Prerequisites 🔗︎

• Thanos operator requires Kubernetes v1.14.x or later.
• For the Helm based installation you need Helm v3.0.2 or later.

1. Create the monitor namespace where the Thanos operator and other components will be deployed.

   CAUTION:

   Prometheus operator and Thanos must be deployed into the same namespace.

   kubectl create namespace monitor
   

2. (Optional) If you want to store your metrics in an object store, complete the following steps.

   1. Create an Object Store secret.

      Example S3 configuration

      cat <<'EOF' >> object-store.yaml
      type: S3
      config:
        endpoint: "s3.eu-west-1.amazonaws.com"
        bucket: "test-bucket"
        region: "eu-west-1"
        access_key: "XXXXXXXXX"
        secret_key: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
      EOF
      

   2. Deploy the secret on Kubernetes

      kubectl create secret generic thanos --from-file=object-store.yaml=object-store.yaml --namespace monitor
      

   3. Create the Thanos sidecar definition. Remember to set externalLabels as it identifies the Prometheus instance for Thanos.

      Extra configuration for prometheus operator.

      cat <<'EOF' >> thanos-sidecar.yaml
      prometheus:
        prometheusSpec:
          thanos:
            image: quay.io/thanos/thanos:v0.17.2
            version: v0.17.2
            objectStorageConfig:
              name: thanos
              key: object-store.yaml
          externalLabels: 
            cluster: thanos-operator-test
      EOF
      

Install the Thanos operator using Helm, the One Eye CLI, or from manifests.

Install the Thanos operator with Helm 🔗︎

To install the Thanos operator with Helm 3, complete the following steps. Alternatively, you can install the Thanos operator with the One Eye CLI.

1. Add the Prometheus operator Helm repository.

   helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
   helm repo update
   

2. Install the Prometheus operator. If you want to use object storage to store your metrics, include the configuration of the Thanos sidecar.

   helm install prometheus-operator --namespace monitor prometheus-community/kube-prometheus-stack -f thanos-sidecar.yaml
   

3. Add the Thanos operator chart repository.

   helm repo add banzaicloud-stable https://kubernetes-charts.banzaicloud.com
   helm repo update
   

4. Install the Thanos operator.

   helm install thanos-operator --namespace monitor banzaicloud-stable/thanos-operator
   

Validate Thanos operator deployment 🔗︎

To verify that the installation was successful, complete the following steps.

1. Check the status of the pods. You should see a new thanos-operator pod.

   $ kubectl -n monitor get pods
   NAME                                        READY   STATUS    RESTARTS   AGE
   thanos-operator-7df8485bf6-gf5gk   1/1     Running   0          13s
   

2. Check the CRDs. You should see the following three new CRDs.

   $  kubectl get crd
   NAME                                    CREATED AT
   objectstores.monitoring.banzaicloud.io      2020-02-07T21:48:20Z
   storeendpoints.monitoring.banzaicloud.io    2020-02-07T21:48:20Z
   thanos.monitoring.banzaicloud.io            2020-02-07T21:48:20Z
   

3. Verify the installation by opening the Thanos query page.
