# Alertmanager
|
|
|
|
As per [prometheus.io documentation](https://prometheus.io/docs/alerting/latest/alertmanager/):
|
|
> The Alertmanager handles alerts sent by client applications such as the
|
|
> Prometheus server. It takes care of deduplicating, grouping, and routing them
|
|
> to the correct receiver integration such as email, PagerDuty, or OpsGenie. It
|
|
> also takes care of silencing and inhibition of alerts.
|
|
|
|
## Prerequisites
|
|
|
|
Kubernetes 1.14+
|
|
|
|
## Usage
|
|
|
|
The chart is distributed as an [OCI Artifact](https://helm.sh/docs/topics/registries/) as well as via a traditional [Helm Repository](https://helm.sh/docs/topics/chart_repository/).
|
|
|
|
- OCI Artifact: `oci://ghcr.io/prometheus-community/charts/alertmanager`
|
|
- Helm Repository: `https://prometheus-community.github.io/helm-charts` with chart `alertmanager`
|
|
|
|
The installation instructions use the OCI registry. Refer to the [`helm repo`]([`helm repo`](https://helm.sh/docs/helm/helm_repo/)) command documentation for information on installing charts via the traditional repository.
|
|
|
|
### Install Chart
|
|
|
|
```console
|
|
helm install [RELEASE_NAME] oci://ghcr.io/prometheus-community/charts/alertmanager
|
|
```
|
|
|
|
_See [configuration](#configuration) below._
|
|
|
|
_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._
|
|
|
|
### Uninstall Chart
|
|
|
|
```console
|
|
helm uninstall [RELEASE_NAME]
|
|
```
|
|
|
|
This removes all the Kubernetes components associated with the chart and deletes the release.
|
|
|
|
_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._
|
|
|
|
### Upgrading Chart
|
|
|
|
```console
|
|
helm upgrade [RELEASE_NAME] [CHART] --install
|
|
```
|
|
|
|
_See [helm upgrade](https://helm.sh/docs/helm/helm_upgrade/) for command documentation._
|
|
|
|
### To 1.0
|
|
|
|
The [configmap-reload](https://github.com/jimmidyson/configmap-reload) container was replaced by the [prometheus-config-reloader](https://github.com/prometheus-operator/prometheus-operator/tree/main/cmd/prometheus-config-reloader).
|
|
Extra command-line arguments specified via configmapReload.prometheus.extraArgs are not compatible and will break with the new prometheus-config-reloader, refer to the [sources](https://github.com/prometheus-operator/prometheus-operator/blob/main/cmd/prometheus-config-reloader/main.go) in order to make the appropriate adjustment to the extea command-line arguments.
|
|
The `networking.k8s.io/v1beta1` is no longer supported. use [`networking.k8s.io/v1`](https://kubernetes.io/docs/reference/using-api/deprecation-guide/#ingressclass-v122).
|
|
|
|
## Configuration
|
|
|
|
See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments, visit the chart's [values.yaml](./values.yaml), or run these configuration commands:
|
|
|
|
```console
|
|
helm show values oci://ghcr.io/prometheus-community/charts/alertmanager
|
|
```
