See this [tutorial](../../REQUIREMENTS.md). * PV support on underlying infrastructure ## Chart Details Note: this chart installs VictoriaMetrics cluster components such as vminsert, vmselect and vmstorage. It doesn't create or configure metrics scraping. If you are looking for a chart to configure monitoring stack in cluster check out [victoria-metrics-k8s-stack chart](https://github.com/VictoriaMetrics/helm-charts/tree/master/charts/victoria-metrics-k8s-stack#helm-chart-for-victoria-metrics-kubernetes-monitoring-stack). ## How to install Access a Kubernetes cluster. ### Setup chart repository (can be omitted for OCI repositories) Add a chart helm repository with follow commands: ```console helm repo add vm https://victoriametrics.github.io/helm-charts/ helm repo update ``` List versions of `vm/victoria-metrics-cluster` chart available to installation: ```console helm search repo vm/victoria-metrics-cluster -l ``` ### Install `victoria-metrics-cluster` chart Export default values of `victoria-metrics-cluster` chart to file `values.yaml`: - For HTTPS repository ```console helm show values vm/victoria-metrics-cluster > values.yaml ``` - For OCI repository ```console helm show values oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-cluster > values.yaml ``` Change the values according to the need of the environment in ``values.yaml`` file. Test the installation with command: - For HTTPS repository ```console helm install vmc vm/victoria-metrics-cluster -f values.yaml -n NAMESPACE --debug --dry-run ``` - For OCI repository ```console helm install vmc oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-cluster -f values.yaml -n NAMESPACE --debug --dry-run ``` Install chart with command: - For HTTPS repository ```console helm install vmc vm/victoria-metrics-cluster -f values.yaml -n NAMESPACE ``` - For OCI repository ```console helm install vmc oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-cluster -f values.yaml -n NAMESPACE ``` Get the pods lists by running this commands: ```console kubectl get pods -A | grep 'vmc' ``` Get the application by running this command: ```console helm list -f vmc -n NAMESPACE ``` See the history of versions of `vmc` application with command. ```console helm history vmc -n NAMESPACE ``` ## How to uninstall Remove application with command. ```console helm uninstall vmc -n NAMESPACE ``` ## Documentation of Helm Chart Install ``helm-docs`` following the instructions on this [tutorial](../../REQUIREMENTS.md). Generate docs with ``helm-docs`` command. ```bash cd charts/victoria-metrics-cluster 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. Change the values according to the need of the environment in ``victoria-metrics-cluster/values.yaml`` file.
