4.2. 为监控配置注解

流程

1. 作为 Operator 的管理员，编辑默认配置以添加 Prometheus 注解，如下所示：

   # Update OPERATOR_NS accordingly
   OPERATOR_NS=rhdh-operator
   kubectl edit configmap backstage-default-config -n "${OPERATOR_NS}"

   Copy to Clipboard Toggle word wrap

2. 在 ConfigMap 中找到 deployment.yaml 键，并将注解添加到 spec.template.metadata.annotations 字段中，如下所示：

   deployment.yaml: |-
     apiVersion: apps/v1
     kind: Deployment
     # --- truncated ---
     spec:
       template:
         # --- truncated ---
         metadata:
           labels:
            rhdh.redhat.com/app:  # placeholder for 'backstage-<cr-name>'
           # --- truncated ---
           annotations:
             prometheus.io/scrape: 'true'
             prometheus.io/path: '/metrics'
             prometheus.io/port: '9464'
             prometheus.io/scheme: 'http'
     # --- truncated ---

   Copy to Clipboard Toggle word wrap
3. 保存您的更改。
