5.16. 监控 Argo CD 自定义资源工作负载

流程

1. 在给定的 Argo CD 实例中，将 .spec.monitoring.enabled 字段值设置为 true ：

   Argo CD 自定义资源示例

   apiVersion: argoproj.io/v1alpha1
   kind: ArgoCD
   metadata:
     name: example-argocd
     labels:
       example: repo
   spec:
     ...
     monitoring:
       enabled: true
     ...

2. 验证 Operator 创建的 PrometheusRule 中是否包含警报规则：

   警报规则示例

   apiVersion: monitoring.coreos.com/v1
   kind: PrometheusRule
   metadata:
     name: argocd-component-status-alert
     namespace: openshift-gitops
   spec:
     groups:
       - name: ArgoCDComponentStatus
         rules:
           ...
           - alert: ApplicationSetControllerNotReady

             annotations:
               message: >-
                 applicationSet controller deployment for Argo CD instance in
                 namespace "default" is not running
             expr: >-
               kube_statefulset_status_replicas{statefulset="openshift-gitops-application-controller statefulset",
               namespace="openshift-gitops"} !=
               kube_statefulset_status_replicas_ready{statefulset="openshift-gitops-application-controller statefulset",
               namespace="openshift-gitops"}
             for: 1m
             labels:
               severity: critical

   PrometheusRule 中的警报规则，用于检查 Argo CD 实例创建的工作负载是否如预期运行。
