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.
