KubernetesNotes11:Ingress限流

1. 官方文档

Annotations - NGINX Ingress Controller

You can add these Kubernetes annotations to specific Ingress objects to customize their behavior. Tip Annotation keys and values can only be strings. Other types, such as boolean or numeric values must be quoted, i.e. "true", "false", "100".
