1. 确认argocd-image-updater已经正确安装且配置正确。
2. 确认Kustomize overlay或patch已经正确配置，Kustomize文件中的镜像路径应该指向argocd-image-updater支持的镜像扫描格式（可参考argocd-image-updater的文档）。
3. 确认Kustomize overlay或patch在部署时被正确应用。
4. 确认 Kubernetes deployment yaml 文件中的镜像路径正确指向了 Kustomize 文件中的路径。
5. 确认新的镜像已经被正确推送到镜像仓库中并能够被Kubernetes集群访问到。

示例代码：

  replicas: 1
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
