ArgoCD notifications Triggers

Triggers 定义应发送通知的条件。定义包括名称、条件 和通知模板参考。条件是一个谓词表达式，如果通知则返回 true 应该发送。

Triggers 列表

1. on-created                        # Application 创建
2. on-deleted                        # Application 删除
3. on-deployed                       # Application 已经同步完成且正常运行。每次提交触发一次。
4. on-health-degraded                # Application 降级
5. on-sync-failed                    # Application 同步失败
6. on-sync-running                   # Application 正在同步
7. on-sync-status-unknown            # Application 状态为 'Unknown'
8. on-sync-succeeded                 # Application 同步成功

Triggers 示例
