在Eureka中使用特定端口注册Spring Boot https应用程序 [英] Register spring boot https application in eureka with specific port

问题描述

我正在尝试注册仅可通过https使用的应用程序.我对正确的配置有疑问，并且在eureka的仪表板上显示的链接不正确.我已经尝试了一些配置，但无法获得正确的效果，即Eureka中的仪表板链接有效.

I am trying to register an application available through https only. I have problem with correct configuration and links displayed in eureka's dashboard are not correct. I have tried some configurations but I can't get the right effect i.e. working dashboard links in Eureka.

我的基本配置.

server:
  port: 9999
  context-path: /ctx
  ssl:
    key-store: classpath:keystore.jks
    key-store-password: 'kspass'
    key-password: 'kpass'
    keyAlias: ssl

spring:
  application:
    name: app-ctx
  cloud:
    loadbalancer:
      retry:
        enabled: true

eureka:
  client:
    serviceUrl:
      defaultZone: https://localhost:8761/eureka/
  instance:
    hostname: localhost
    secure-port-enabled: true
    non-secure-port-enabled: false
    secure-port: ${server.port}
    health-check-url: https://${eureka.hostname}:XYZ/ctx/health
    status-page-url: https://${eureka.hostname}:XYZ/ctx/info
    home-page-url: https://${eureka.hostname}:XYZ/ctx

我尝试了以下版本的运行状况/状态/家庭网址:

I have tried following versions of health/status/home URLs:

1. 不带端口的绝对URL

1. Absolute URLs without port

例如:health-check-url:https://$ {eureka.hostname}/ctx/health

Example: health-check-url: https://${eureka.hostname}/ctx/health

结果:https://localhost/ctx/info

Result: https://localhost/ctx/info

替换$ {server.port}的绝对URL

Absolute URLs with ${server.port} replacement

例如:health-check-url:https://$ {eureka.hostname}:$ {server.port}/ctx/health)

Example: health-check-url: https://${eureka.hostname}:${server.port}/ctx/health)

结果:$ {server.port}未解析，仪表板中的URL为: https://localhost:$ {server.port}/ctx/info

Result: ${server.port} not resolved, url in dashboard is: https://localhost:${server.port}/ctx/info

相对网址

示例:health-check-url-path:/ctx/health

Example: health-check-url-path: /ctx/health

结果: http://localhost:9999/ctx/info，没有https.

Result: http://localhost:9999/ctx/info, no https.

最后一个与我的预期非常接近，但是没有没有https .

Last one is quite close to my expectations, but there is no https.

推荐答案

最后，我已经解决了我的问题.不确定它是否是最好的，因为据我所知，它不适用于随机端口，即server.port =0.在这种情况下，eureka使用端口0注册应用程序，并且在仪表板上存在与未转发端口的链接来纠正位置，这不是预期的行为.

Finally I've got solution for my problem. Not sure it that's the best one because as far as I can see it doesn't work with random ports i.e. server.port = 0. In that case eureka registers application with port 0 and on dashboard there is link with port that does not forward to correct location and that's not expected behavior.

代替使用与当前应用程序相关的$ {server.port}占位符，我们必须使用eureka的$ {eureka.instance.secure-port}配置部分

Instead of using ${server.port} placeholder that is related to current application we have to use eureka's part of configuration ${eureka.instance.secure-port} i.e.

server:
  port: 9999
  context-path: /ctx
  ssl:
    key-store: classpath:keystore.jks
    key-store-password: 'kspass'
    key-password: 'kpass'
    keyAlias: ssl

spring:
  application:
    name: app-ctx
  cloud:
    loadbalancer:
      retry:
        enabled: true

eureka:
  client:
    serviceUrl:
      defaultZone: https://localhost:8761/eureka/
  instance:
    hostname: localhost
    secure-port-enabled: true
    non-secure-port-enabled: false
    secure-port: ${server.port}
    health-check-url: https://${eureka.instance.hostname}:${eureka.instance.secure-port}/ctx/health
    status-page-url: https://${eureka.instance.hostname}:${eureka.instance.secure-port}/ctx/info
    home-page-url: https://${eureka.instance.hostname}:${eureka.instance.secure-port}/ctx
