The shortest way to deploy full-stack monitoring cluster with VictoriaMetrics Operator is to use Helm-chart [victoria-metrics-k8s-stack](https://victoriametrics.github.io/helm-charts/charts/victoria-metrics-k8s-stack/). Also you can follow the other steps in documentation to use VictoriaMetrics Operator: - [Setup](./setup.md) - [Security](./security.md) - [Configuration](./configuration.md) - [Migration from Prometheus](./migration.md) - [Monitoring](./monitoring.md) - [Authorization and exposing components](./auth.md) - [High Availability](./high-availability.md) - [Enterprise](./enterprise.md) - [Custom resources](./resources/README.md) - [FAQ (Frequency Asked Questions)](./FAQ.md) But if you want to deploy VictoriaMetrics Operator quickly from scratch (without using templating for custom resources), you can follow this guide: - [Setup operator](#setup-operator) - [Deploy components](#deploy-components) - [VMCluster](#vmcluster-vmselect-vminsert-vmstorage) - [Scraping](#scraping) - [VMAgent](#vmagent) - [VMServiceScrape](#vmservicescrape) - [Access](#access) - [VMAuth](#vmauth) - [VMUser](#vmuser) - [Alerting](#alerting) - [VMAlertmanager](#vmalertmanager) - [VMAlert](#vmalert) - [VMRule](#vmrule) - [VMUser](#vmuser-update) - [Anythings else?](#anythings-else) Let's start! ## Setup operator You can find out how to and instructions for installing the VictoriaMetrics operator into your kubernetes cluster on the [Setup page](./setup.md). Here we will elaborate on just one of the ways - for instance, we will install operator via Helm-chart [victoria-metrics-operator](https://github.com/VictoriaMetrics/helm-charts/blob/master/charts/victoria-metrics-operator/README.md): Add repo with helm-chart: ```shell helm repo add vm https://victoriametrics.github.io/helm-charts/ helm repo update ``` Render `values.yaml` with default operator configuration: ```shell helm show values vm/victoria-metrics-operator > values.yaml ``` Now you can configure operator - open rendered `values.yaml` file in your text editor. For example: ```shell code values.yaml ``` Now you can change configuration in `values.yaml`. For more details about configuration options and methods, see [configuration -> victoria-metrics-operator](./configuration.md#victoria-metrics-operator). If you migrated from prometheus-operator, you can read about prometheus-operator objects conversion on the [migration from prometheus-operator](./migration.md). Since we're looking at installing from scratch, let's disable prometheus-operator objects conversion, and also let's set some resources for operator in `values.yaml`: ```yaml # ... operator: # -- By default, operator converts prometheus-operator objects. disable_prometheus_converter: true # -- Resources for operator resources: limits: cpu: 500m memory: 500Mi requests: cpu: 100m memory: 150Mi # ... ``` You will need a kubernetes namespace to deploy the operator and VM components. Let's create it: ```shell kubectl create namespace vm ``` After finishing with `values.yaml` and creating namespace, you can test the installation with command: ```shell helm install vmoperator vm/victoria-metrics-operator -f values.yaml -n vm --debug --dry-run ``` Where `vm` is the namespace where you want to install operator. If everything is ok, you can install operator with command: ```shell helm install vmoperator vm/victoria-metrics-operator -f values.yaml -n vm # NAME: vmoperator # LAST DEPLOYED: Thu Sep 14 15:13:04 2023 # NAMESPACE: vm # STATUS: deployed # REVISION: 1 # TEST SUITE: None # NOTES: # victoria-metrics-operator has been installed. Check its status by running: # kubectl --namespace vm get pods -l "app.kubernetes.io/instance=vmoperator" # # Get more information on https://github.com/VictoriaMetrics/helm-charts/tree/master/charts/victoria-metrics-operator. # See "Getting started guide for VM Operator" on https://docs.victoriametrics.com/guides/getting-started-with-vm-operator.html . ``` And check that operator is running: ```shell kubectl get pods -n vm -l "app.kubernetes.io/instance=vmoperator" # NAME READY STATUS RESTARTS AGE # vmoperator-victoria-metrics-operator-7b88bd6df9-q9qwz 1/1 Running 0 98s ``` ## Deploy components Now you can create instances of VictoriaMetrics applications. Let's create fullstack monitoring cluster with [`vmagent`](./resources/vmagent.md), [`vmauth`](./resources/vmauth.md), [`vmalert`](./resources/vmalert.md), [`vmalertmanager`](./resources/vmalertmanager.md), [`vmcluster`](./resources/vmcluster.md) (a component for deploying a cluster version of [VictoriaMetrics](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#architecture-overview) consisting of `vmstorage`, `vmselect` and `vminsert`): More details about resources of VictoriaMetrics operator you can find on the [resources page](./resources/README.md). ### VMCluster (vmselect, vminsert, vmstorage) Let's start by deploying the [`vmcluster`](./resources/vmcluster.md) resource. Create file `vmcluster.yaml` ```shell code vmcluster.yaml ``` with the following content: ```yaml # vmcluster.yaml apiVersion: operator.victoriametrics.com/v1beta1 kind: VMCluster metadata: name: demo spec: retentionPeriod: "1" replicationFactor: 2 vmstorage: replicaCount: 2 storageDataPath: "/vm-data" storage: volumeClaimTemplate: spec: resources: requests: storage: "10Gi" resources: limits: cpu: "1" memory: "1Gi" vmselect: replicaCount: 2 cacheMountPath: "/select-cache" storage: volumeClaimTemplate: spec: resources: requests: storage: "1Gi" resources: limits: cpu: "1" memory: "1Gi" requests: cpu: "0.5" memory: "500Mi" vminsert: replicaCount: 2 resources: limits: cpu: "1" memory: "1Gi" requests: cpu: "0.5" memory: "500Mi" ``` After that you can deploy `vmcluster` resource to the kubernetes cluster: ```shell kubectl apply -f vmcluster.yaml -n vm # vmcluster.operator.victoriametrics.com/demo created ``` Check that `vmcluster` is running: ```shell kubectl get pods -n vm -l "app.kubernetes.io/instance=demo" # NAME READY STATUS RESTARTS AGE # vminsert-demo-8688d88ff7-fnbnw 1/1 Running 0 3m39s # vminsert-demo-8688d88ff7-5wbj7 1/1 Running 0 3m39s # vmselect-demo-0 1/1 Running 0 3m39s # vmselect-demo-1 1/1 Running 0 3m39s # vmstorage-demo-1 1/1 Running 0 22s # vmstorage-demo-0 1/1 Running 0 6s ``` Now you can see that 6 components of your demo vmcluster is running. In addition, you can see that the operator created services for each of the component type: ```shell kubectl get svc -n vm -l "app.kubernetes.io/instance=demo" # NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE # vmstorage-demo ClusterIP None 8482/TCP,8400/TCP,8401/TCP 8m3s # vmselect-demo ClusterIP None 8481/TCP 8m3s # vminsert-demo ClusterIP 192.168.194.183 8480/TCP 8m3s ``` We'll need them in the next steps. More information about `vmcluster` resource you can find on the [vmcluster page](./resources/vmcluster.md). ### Scraping #### VMAgent Now let's deploy [`vmagent`](./resources/vmagent.md) resource. Create file `vmagent.yaml` ```shell code vmagent.yaml ``` with the following content: ```yaml apiVersion: operator.victoriametrics.com/v1beta1 kind: VMAgent metadata: name: demo spec: selectAllByDefault: true remoteWrite: - url: "http://vminsert-demo.vm.svc:8480/insert/0/prometheus/api/v1/write" ``` After that you can deploy `vmagent` resource to the kubernetes cluster: ```shell kubectl apply -f vmagent.yaml -n vm # vmagent.operator.victoriametrics.com/demo created ``` Check that `vmagent` is running: ```shell kubectl get pods -n vm -l "app.kubernetes.io/instance=demo" -l "app.kubernetes.io/name=vmagent" # NAME READY STATUS RESTARTS AGE # vmagent-demo-6785f7d7b9-zpbv6 2/2 Running 0 72s ``` More information about `vmagent` resource you can find on the [vmagent page](./resources/vmagent.md). #### VMServiceScrape Now we have the timeseries database (vmcluster) and the tool to collect metrics (vmagent) and send it to the database. But we need to tell vmagent what metrics to collect. For this we will use [`vmservicescrape`](./resources/vmservicescrape.md) resource or [other `*scrape` resources](./resources/README.md). By default, operator creates `vmservicescrape` resource for each component that it manages. More details about this you can find on the [monitoring page](./configuration.md#monitoring-of-cluster-components). For instance, we can create `vmservicescrape` for VictoriaMetrics operator manually. Let's create file `vmservicescrape.yaml`: ```shell code vmservicescrape.yaml ``` with the following content: ```yaml apiVersion: operator.victoriametrics.com/v1beta1 kind: VMServiceScrape metadata: name: vmoperator-demo spec: selector: matchLabels: app.kubernetes.io/instance: vmoperator app.kubernetes.io/name: victoria-metrics-operator namespaceSelector: matchNames: - vm ``` After that you can deploy `vmservicescrape` resource to the kubernetes cluster: ```shell kubectl apply -f vmservicescrape.yaml -n vm # vmservicescrape.operator.victoriametrics.com/vmoperator-demo created ``` ### Access We need to look at the results of what we got. Up until now, we've just been looking only at the status of the pods. #### VMAuth Let's expose our components with [`vmauth`](./resources/vmauth.md). Create file `vmauth.yaml` ```shell code vmauth.yaml ``` with the following content: ```yaml apiVersion: operator.victoriametrics.com/v1beta1 kind: VMAuth metadata: name: demo spec: userNamespaceSelector: {} userSelector: {} ingress: class_name: nginx # <-- change this to your ingress-controller host: vm-demo.k8s.orb.local # <-- change this to your domain ``` **Note** that content of `ingress` field depends on your ingress-controller and domain. Your cluster will have them differently. Also, for simplicity, we don't use tls, but in real environments not having tls is unsafe. #### VMUser To get authorized access to our data it is necessary to create a user using the [vmuser](./resources/vmuser.md) resource. Create file `vmuser.yaml` ```shell code vmuser.yaml ``` with the following content: ```yaml apiVersion: operator.victoriametrics.com/v1beta1 kind: VMUser metadata: name: demo spec: name: demo username: demo generatePassword: true targetRefs: # vmui + vmselect - crd: kind: VMCluster/vmselect name: demo namespace: vm target_path_suffix: "/select/0" paths: - "/vmui" - "/vmui/.*" - "/prometheus/api/v1/query" - "/prometheus/api/v1/query_range" - "/prometheus/api/v1/series" - "/prometheus/api/v1/label/" - "/prometheus/api/v1/label/[^/]+/values" ``` After that you can deploy `vmauth` and `vmuser` resources to the kubernetes cluster: ```shell kubectl apply -f vmauth.yaml -n vm kubectl apply -f vmuser.yaml -n vm # vmauth.operator.victoriametrics.com/demo created # vmuser.operator.victoriametrics.com/demo created ``` Operator automatically creates a secret with username/password token for `VMUser` resource with `generatePassword=true`: ```shell kubectl get secret -n vm -l "app.kubernetes.io/instance=demo" -l "app.kubernetes.io/name=vmuser" # NAME TYPE DATA AGE # vmuser-demo Opaque 3 29m ``` You can get password for your user with command: ```shell kubectl get secret -n vm vmuser-demo -o jsonpath="{.data.password}" | base64 --decode # Yt3N2r3cPl ``` Now you can get access to your data with url `http://vm-demo.k8s.orb.local/vmui`, username `demo` and your given password (`Yt3N2r3cPl` in our case): ### Alerting The remaining components will be needed for alerting. #### VMAlertmanager Let's start with [`vmalertmanager`](./resources/vmalertmanager.md). Create file `vmuser.yaml` ```shell code vmuser.yaml ``` with the following content: ```yaml apiVersion: operator.victoriametrics.com/v1beta1 kind: VMAlertmanager metadata: name: demo spec: configRawYaml: | global: resolve_timeout: 5m route: group_wait: 30s group_interval: 5m repeat_interval: 12h receiver: 'webhook' receivers: - name: 'webhook' webhook_configs: - url: 'http://your-webhook-url' ``` where webhook-url is the address of the webhook to receive notifications (configuration of AlertManager notifications will remain out of scope). You can find more details about `alertmanager` configuration in the [Alertmanager documentation](https://prometheus.io/docs/alerting/latest/configuration/). After that you can deploy `vmalertmanager` resource to the kubernetes cluster: ```shell kubectl apply -f vmalertmanager.yaml -n vm # vmalertmanager.operator.victoriametrics.com/demo created ``` Check that `vmalertmanager` is running: ```shell kubectl get pods -n vm -l "app.kubernetes.io/instance=demo" -l "app.kubernetes.io/name=vmalertmanager" # NAME READY STATUS RESTARTS AGE # vmalertmanager-demo-0 2/2 Running 0 107s ``` #### VMAlert And now you can create [`vmalert`](./resources/vmalert.md) resource. Create file `vmalert.yaml` ```shell code vmalert.yaml ``` with the following content: ```yaml apiVersion: operator.victoriametrics.com/v1beta1 kind: VMAlert metadata: name: demo spec: datasource: url: "http://vmselect-demo.vm.svc:8481/select/0/prometheus" remoteWrite: url: "http://vminsert-demo.vm.svc:8480/insert/0/prometheus" remoteRead: url: "http://vmselect-demo.vm.svc:8481/select/0/prometheus" notifier: url: "http://vmalertmanager-demo.vm.svc:9093" evaluationInterval: "30s" selectAllByDefault: true # for accessing to vmalert via vmauth with path prefix extraArgs: http.pathPrefix: /vmalert ``` After that you can deploy `vmalert` resource to the kubernetes cluster: ```shell kubectl apply -f vmalert.yaml -n vm # vmalert.operator.victoriametrics.com/demo created ``` Check that `vmalert` is running: ```shell kubectl get pods -n vm -l "app.kubernetes.io/instance=demo" -l "app.kubernetes.io/name=vmalert" # NAME READY STATUS RESTARTS AGE # vmalert-demo-bf75c67cb-hh4qd 2/2 Running 0 5s ``` #### VMRule Now you can create [vmrule](./resources/vmrule.md) resource for [vmalert](./resources/vmalert.md). Create file `vmrule.yaml` ```shell code vmrule.yaml ``` with the following content: {% raw %} ```yaml apiVersion: operator.victoriametrics.com/v1beta1 kind: VMRule metadata: name: demo spec: groups: - name: vmalert rules: - alert: vmalert config reload error expr: delta(vmalert_config_last_reload_errors_total[5m]) > 0 for: 10s labels: severity: major job: "{{ $labels.job }}" annotations: value: "{{ $value }}" description: 'error reloading vmalert config, reload count for 5 min {{ $value }}' ``` {% endraw %} After that you can deploy `vmrule` resource to the kubernetes cluster: ```shell kubectl apply -f vmrule.yaml -n vm # vmrule.operator.victoriametrics.com/demo created ``` #### VMUser update Let's update our user with access to `vmalert` and `vmalertmanager`: ```shell code vmuser.yaml ``` ```yaml apiVersion: operator.victoriametrics.com/v1beta1 kind: VMUser metadata: name: demo spec: name: demo username: demo generatePassword: true targetRefs: # vmui + vmselect - crd: kind: VMCluster/vmselect name: demo namespace: vm target_path_suffix: "/select/0" paths: - "/vmui" - "/vmui/.*" - "/prometheus/api/v1/query" - "/prometheus/api/v1/query_range" - "/prometheus/api/v1/series" - "/prometheus/api/v1/label/" - "/prometheus/api/v1/label/[^/]+/values" # vmalert - crd: kind: VMAlert name: demo namespace: vm paths: - "/vmalert" - "/vmalert/.*" - "/api/v1/groups" - "/api/v1/alert" - "/api/v1/alerts" ``` After that you can deploy `vmuser` resource to the kubernetes cluster: ```shell kubectl apply -f vmuser.yaml -n vm # vmuser.operator.victoriametrics.com/demo created ``` And now you can get access to your data with url `http://vm-demo.k8s.orb.local/vmalert` (for your environment it most likely will be different) with username `demo`: ## Anything else That's it. We obtained a monitoring cluster corresponding to the target topology: You have a full-stack monitoring cluster with VictoriaMetrics Operator.
