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

helm repo update

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

for helm v3

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

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

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

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

Test the installation with command:

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

Install chart with command:

for helm v3

helm install vmalert vm/victoria-metrics-alert -f values.yaml -n NAMESPACE

Get the pods lists by running this commands:

kubectl get pods -A | grep 'alert'

Get the application by running this command:

helm list -f vmalert -n NAMESPACE

See the history of versions of vmalert application with command.

helm history vmalert -n NAMESPACE

HA configuration for Alertmanager

There is no option on this chart to set up Alertmanager with HA mode. To enable the HA configuration, you can use:

Documentation of Helm Chart

Install helm-docs following the instructions on this tutorial.

Generate docs with helm-docs command.

cd charts/victoria-metrics-alert

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-alert/values.yaml file.
