This repository packages the upstream metio/matrix-alertmanager-receiver container as a reusable Helm chart. It does not rebuild or mirror the upstream image. The chart owns the ConfigMap, Deployment, Service, probes, and optional ServiceMonitor. Set the Matrix homeserver, bot ID, room mapping, and existing Secret reference in values; never put an access token in Helm values.

The image tag defaults to the chart's appVersion. The Git tag follows the upstream application release; CI derives package versions with git describe --tags --long. A tag release packages without the leading v; later chart-only commits append their distance and commit hash.

For the public chart repository:

helm repo add brunner.ninja https://brunner.ninja/charts
helm repo update brunner.ninja
helm search repo brunner.ninja/matrix-alertmanager-receiver

For a local install from this checkout, create the referenced Kubernetes Secret first, then run NAMESPACE=prometheus ./chart/install.sh with the appropriate values file. Argo CD is the normal deployment path in this cluster.
