The `VMAlertmanagerConfig` provides way to configure [VMAlertmanager](https://docs.victoriametrics.com/operator/resources/vmalertmanager)
|
|
configuration with CRD. It allows to define different configuration parts, which will be merged by operator into config.
|
|
|
|
It behaves like other config parts - `VMServiceScrape` and etc.
|
|
|
|
Read [Usage](#usage) and [Special case](#special-case) before using.
|
|
|
|
## Specification
|
|
|
|
You can see the full actual specification of the `VMAlertmanagerConfig` resource in
|
|
the **[API docs -> VMAlertmanagerConfig](https://docs.victoriametrics.com/operator/api#vmalertmanagerconfig)**.
|
|
|
|
Also, you can check out the [examples](#examples) section.
|
|
|
|
## Validation
|
|
|
|
The operator performs validation of `VMAlertmanagerConfig`. In case of any misconfiguration it adds corresponding validation fail message into `status.lastSyncError` field and updates `status.status` field to `failed` status.
|
|
|
|
For example `VMAlertmanagerConfig` without required fields:
|
|
|
|
```yaml
|
|
apiVersion: operator.victoriametrics.com/v1beta1
|
|
kind: VMAlertmanagerConfig
|
|
metadata:
|
|
name: invalid-config
|
|
namespace: default
|
|
spec:
|
|
receivers:
|
|
- name: blackhole
|
|
- name: pagerduty
|
|
pagerduty_configs:
|
|
- url: http://example
|
|
route:
|
|
group_by:
|
|
- alertname
|
|
receiver: blackhole
|
|
routes:
|
|
- matchers:
|
|
- alertname="pd"
|
|
receiver: pagerduty
|
|
status:
|
|
lastErrorParentAlertmanagerName: default/example-alertmanager
|
|
lastSyncError: 'receiver at idx=2 is invalid: at idx=0 pagerduty_configs one of
|
|
''routing_key'' or ''service_key'' must be configured'
|
|
lastSyncErrorTimestamp: 1722950290
|
|
status: failed
|
|
```
|
|
|
|
## Usage
|
|
|
|
`VMAlertmanagerConfig` allows delegating notification configuration to the kubernetes cluster users.
|
|
The application owner may configure notifications by defining it at `VMAlertmanagerConfig`.
|
|
|
|
With the combination of `VMRule` and `VMServiceScrape` it allows delegating configuration observability to application owners, and uses popular `GitOps` practice.
|
|
|
|
Operator combines `VMAlertmanagerConfig`s into a single configuration file for `VMAlertmanager`.
|
|
|
|
```yaml
|
|
apiVersion: operator.victoriametrics.com/v1beta1
|
|
kind: VMAlertmanagerConfig
|
|
metadata:
|
|
name: example-email-web
|
|
namespace: production
|
|
spec:
|
|
route:
|
|
receiver: email
|
|
group_interval: 1m
|
|
routes:
|
|
- receiver: email
|
|
matchers:
|
|
- {severity =~ "warning|critical", app_name = "blog"}
|
|
receivers:
|
|
- name: email
|
|
email_configs:
|
|
- to: some-email@example.com
|
|
from: alerting@example.com
|
|
smarthost: example.com:25
|
|
text: ALARM
|
|
```
|
|
|
|
#### Special Case
|
|
|
|
VMAlertmanagerConfig has enforced namespace matcher.
|
|
Alerts must have a proper namespace label, with the same value as name of namespace for VMAlertmanagerConfig.
|
|
|
|
It can be disabled, by setting the following value to the VMAlertmanager: `spec.disableNamespaceMatcher: true`.
|
|
|
|
