Spring Cloud Consult健康检查和GCP上的状态配置

Question

我们正在尝试在GCP计算引擎上向consul注册一个spring cloud consul应用程序，它可以向consur注册该应用程序，但该应用程序面临两个问题。下面是引导。yaml和服务器。应用程序的yaml，

<代码>应用程序。yaml

server:
  port: 10003
spring:
  application:
    name: hello-service
  cloud:
    consul:
      enabled: true
    inetutils:
      useOnlySiteLocalInterfaces: true
  endpoints:
    actuator:
      sensitive: false

<代码>引导。yaml

spring:
  cloud:
    consul:
      enabled: true
      host: 10.160.0.18
      port: 8500
      discovery:
        prefer-ip-address: true

1. Consul无法在计算引擎上调用运行状况检查，可能是因为它已在实例的内部域名上注册。

带有领事的服务：NewService{id='hello-service-10003'，name='hello-service'，tags=[secure=false]，address='consur-app-test.c.name-of-project.internal'，meta=null，port=10003，enableTagOverride=null，check=check{script null'，interval='10s'，ttl='null'，http='0http://consul-app-test.c.name-of-project.internal:10003/actuator/health'，方法='null'，头={}，tcp='null'，超时='null'，deregisterCriticalServiceAfter='null'，tlsSkipVerify=null，状态='null'，检查=null}

Answer 1

如果你像我一样使用版本2.1.2：org.springframework.cloud：spring-Cloud-starter-consul-发现：2.1.2。RELEASE

您可以设置：

spring:

  cloud:
    consul:
      host: localhost #  consul的地址
      port: 8500 # consul 的端口
      discovery:
        prefer-ip-address: true  # // This must be matched
        tags: version=1.0
        instance-id: ${spring.application.name}:${spring.cloud.client.ip-address}
        healthCheckPath: /actuator/health # 服务做健康检查的端口
        healthCheckInterval: 15s  # 服务健康检查的周期
        healthCheckTimeout: 60s # 服务检查是的timeout时长
        healthCheckCriticalTimeout: 5m # 服务健康检查失败5分钟后，删除服务

您可以在ConsultDiscoveryProperties中查看源代码：

@ConfigurationProperties("spring.cloud.consul.discovery")
public class ConsulDiscoveryProperties {

……

    /** Is service discovery enabled? */
    private boolean enabled = true;

    /** Alternate server path to invoke for health checking. */
    private String healthCheckPath = "/actuator/health";

    /** Custom health check url to override default. */
    private String healthCheckUrl;

    /** How often to perform the health check (e.g. 10s), defaults to 10s. */
    private String healthCheckInterval = "10s";

    /** Timeout for health check (e.g. 10s). */
    private String healthCheckTimeout;

    /**
     * Timeout to deregister services critical for longer than timeout (e.g. 30m).
     * Requires consul version 7.x or higher.
     */
    private String healthCheckCriticalTimeout;
……

Answer 2

我在应用程序中做了一些更改。yaml和bootstrap。为我工作的yaml。

应用亚马尔

spring:
  application:
    name: hello-service
  cloud:
    consul:
      discovery:
        instanceId: ${spring.application.name}:${random.value}
        health-check-critical-timeout: 3m
        prefer-ip-address: true # disable if we want to use google cloud internal DNS 

独自创立亚马尔

spring:
  cloud:
    consul:
      enabled: true
      host: 10.160.0.18
      port: 8500
