Service Fabric群集自定义终结点与应用程序开始和结束端口 [英] Service Fabric Cluster Custom endpoints vs Application start and end ports

问题描述

此屏幕快照是在Azure门户上创建群集时拍摄的.如下图所示，

This screenshot was taken while creating a cluster on the Azure portal. As given in the picture below,

1. 自定义端点和应用程序之间有什么区别 起始端口范围?

1. what is the difference between Custom endpoint and application start-end port range?

为什么一个被称为端点，另一个被称为端口?

Why is one called an endpoint and the other called a port?

自定义端点帮助显示为"Custom endpoints allow for connections to applications running on this node type. Enter endpoints separated by a comma.".

The custom endpoints help says "Custom endpoints allow for connections to applications running on this node type. Enter endpoints separated by a comma.".

推荐答案

在文档

In the documentation here and here it is explained in a very clear way,

自定义终结点:该字段允许您输入一个逗号分隔的端口列表，这些端口要通过Azure负载平衡器公开到应用程序的公共Internet .例如，如果您打算将Web应用程序部署到您的集群，请输入"80".在此处允许端口80上的流量进入您的群集.

Custom endpoints: This field allows you to enter a comma-separated list of ports that you want to expose through the Azure Load Balancer to the public Internet for your applications. For example, if you plan to deploy a web application to your cluster, enter "80" here to allow traffic on port 80 into your cluster.

应用程序端口(开始|结束):是Service Fabric应用程序使用的端口.应用程序端口范围应足够大，以覆盖您的应用程序的端点要求.此范围应与计算机上的动态端口范围(即配置中设置的EphemeralPorts范围)互斥.每当需要新端口时，Service Fabric都会使用这些端口，并负责为这些端口打开防火墙.

Application Ports (Start|End): are the ports that are used by the Service Fabric applications. The application port range should be large enough to cover the endpoint requirement of your applications. This range should be exclusive from the dynamic port range on the machine, that is, the EphemeralPorts range as set in the configuration. Service Fabric uses these ports whenever new ports are required and takes care of opening the firewall for these ports.

摘要:

自定义端点是在负载均衡器中打开的端口，用于启用外部访问.

Custom endpoints are ports opened in the Load Balancer to enable external access.

应用程序端口是在使用动态分配的端口时将在节点中打开并分配给服务但不能从外部访问的保留端口的范围.

Application Ports is a range of reserved ports to be opened in the nodes and assigned to services when using dynamic allocated ports, but not externally accessible.
