Victoria Metrics Single version - high-performance, cost-effective and scalable TSDB, long-term remote storage for Prometheus

Prerequisites

• Install the follow packages: git, kubectl, helm, helm-docs. See this tutorial.
• PV support on underlying infrastructure.

Chart Details

This chart will do the following:

• Rollout Victoria Metrics Single.

How to install

Access a Kubernetes cluster.

Setup chart repository (can be omitted for OCI repositories)

Add a chart helm repository with follow commands:

helm repo add vm https://victoriametrics.github.io/helm-charts/

helm repo update

List versions of vm/victoria-metrics-single chart available to installation:

helm search repo vm/victoria-metrics-single -l

Install victoria-metrics-single chart

Export default values of victoria-metrics-single chart to file values.yaml:

• For HTTPS repository

  helm show values vm/victoria-metrics-single > values.yaml
  

• For OCI repository

  helm show values oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-single > values.yaml
  

Change the values according to the need of the environment in values.yaml file.

Test the installation with command:

• For HTTPS repository

  helm install vms vm/victoria-metrics-single -f values.yaml -n NAMESPACE --debug --dry-run
  

• For OCI repository

  helm install vms oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-single -f values.yaml -n NAMESPACE --debug --dry-run
  

Install chart with command:

• For HTTPS repository

  helm install vms vm/victoria-metrics-single -f values.yaml -n NAMESPACE
  

• For OCI repository

  helm install vms oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-single -f values.yaml -n NAMESPACE
  

Get the pods lists by running this commands:

kubectl get pods -A | grep 'vms'

Get the application by running this command:

helm list -f vms -n NAMESPACE

See the history of versions of vms application with command.

helm history vms -n NAMESPACE

How to uninstall

Remove application with command.

helm uninstall vms -n NAMESPACE

Documentation of Helm Chart

Install helm-docs following the instructions on this tutorial.

Generate docs with helm-docs command.

cd charts/victoria-metrics-single

helm-docs

The markdown generation is entirely go template driven. The tool parses metadata from charts and generates a number of sub-templates that can be referenced in a template file (by default README.md.gotmpl). If no template file is provided, the tool has a default internal template that will generate a reasonably formatted README.

Parameters

The following tables lists the configurable parameters of the chart and their default values.
