# velero-pvc-watcher

[![Build Status](https://cloud.drone.io/api/badges/bitsbeats/velero-pvc-watcher/status.svg)](https://cloud.drone.io/bitsbeats/velero-pvc-watcher)

[![Go Report](https://goreportcard.com/badge/github.com/bitsbeats/velero-pvc-watcher)](https://goreportcard.com/badge/github.com/bitsbeats/velero-pvc-watcher)

velero-pvc-watcher is a Prometheus exporter that monitores all PVCs in the cluster and verifies that a matching `backup.velero.io/backup-volumes` or a `backup.velero.io/backup-volumes-excludes` is set.

Note: Due to the design all unmounted PVCs will reported as not being backuped, since there is no configuration for them.

## Installation

Helm Chart

https://github.com/bitsbeats/helm-charts

```sh

helm repo add bitsbeats https://bitsbeats.github.io/helm-charts/

helm upgrade -i --namespace  bitsbeats/velero-pvc-watcher

```

You can now scrape the metrics directly via prometheus kubernetes discovery, annotations:

| annotation           | default value |

|----------------------|---------------|

| prometheus.io/scrape | true          |

| prometheus.io/port   | 2112          |

| prometheus.io/path   | /metrics      |

## Example StatefulSet config

**Note**: The names come from `pod.spec.volumes`, not the pvc name.

```

apiVersion: apps/v1

kind: StatefulSet

spec:

  template:

    metadata:

      annotations:

        backup.velero.io/backup-volumes: data,logging

        backup.velero.io/backup-volumes-excludes: tmp

```

## Example PVC config

To exclude a PVC that is not in use from backups annotate it as follows:

```yaml

apiVersion: v1

kind: PersistentVolumeClaim

metadata:

  annotations:

    backup.velero.io/backup-excluded: "true"

```

## Example Alertmanager config

```

alert: Velero PVC Check

for: 10m

expr: |

  backupmonitor_missing != 0

labels:

  severity: warning

annotations:

  text: >-

    The pvc {{ $labels.pvc_name }} in namespace {{ $labels.namespace }} has no backup annotation.

  action: >-

    Either configure a backup or exclude the volume from backup. For more
