检测configMap，重载Pod内的业务容器

标签：interface   ima   when   and   ace   tar   update   which   自动   

Usage：

使用sidecar模式，跟业务进程运行在同一个Pod内，检测到configMap更新后，会自动触发Hook

       - name: prometheus-server-configmap-reload
          image: ‘jimmidyson/configmap-reload:v0.3.0‘
          args:
            - ‘--volume-dir=/etc/config‘
            - ‘--webhook-url=http://127.0.0.1:9090/-/reload‘       # 以prometheus为例，调用prom的reload api
          resources: {}
          volumeMounts:
            - name: config-volume
              readOnly: true
              mountPath: /etc/config
