Victoria Metrics Anomaly Detection - a service that continuously scans Victoria Metrics time series and detects unexpected changes within data patterns in real-time.
## Prerequisites
* Install the follow packages: ``git``, ``kubectl``, ``helm``, ``helm-docs``. See this [tutorial](https://docs.victoriametrics.com/helm/requirements/).
* PV support on underlying infrastructure
## Chart Details
This chart will do the following:
* Rollout victoria metrics anomaly
## 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-anomaly` chart available to installation:
```console
helm search repo vm/victoria-metrics-anomaly -l
```
### Install `victoria-metrics-anomaly` chart
Export default values of `victoria-metrics-anomaly` chart to file `values.yaml`:
- For HTTPS repository
```console
helm show values vm/victoria-metrics-anomaly > values.yaml
```
- For OCI repository
```console
helm show values oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-anomaly > 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 vma vm/victoria-metrics-anomaly -f values.yaml -n NAMESPACE --debug --dry-run
```
- For OCI repository
```console
helm install vma oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-anomaly -f values.yaml -n NAMESPACE --debug --dry-run
```
Install chart with command:
- For HTTPS repository
```console
helm install vma vm/victoria-metrics-anomaly -f values.yaml -n NAMESPACE
```
- For OCI repository
```console
helm install vma oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-anomaly -f values.yaml -n NAMESPACE
```
Get the pods lists by running this commands:
```console
kubectl get pods -A | grep 'vma'
```
Get the application by running this command:
```console
helm list -f vma -n NAMESPACE
```
See the history of versions of `vma` application with command.
```console
helm history vma -n NAMESPACE
```
## How to uninstall
Remove application with command.
```console
helm uninstall vma -n NAMESPACE
```
## Documentation of Helm Chart
Install ``helm-docs`` following the instructions on this [tutorial](https://docs.victoriametrics.com/helm/requirements/).
Generate docs with ``helm-docs`` command.
```bash
cd charts/victoria-metrics-anomaly
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.
For more `vmanomaly` config parameters see https://docs.victoriametrics.com/anomaly-detection/components
Change the values according to the need of the environment in ``victoria-metrics-anomaly/values.yaml`` file.
