VMAlertmanagerConfig

The VMAlertmanagerConfig provides way to configure 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 and Special case before using.

Specification

You can see the full actual specification of the VMAlertmanagerConfig resource in the API docs -> VMAlertmanagerConfig.

Also, you can check out the examples section.

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 VMAlertmanagerConfigs into a single configuration file for VMAlertmanager.

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.
