使用spring cloud consul時如何注銷consul中的服務

Question

我使用 consul( docker.io/bitnami/consul:1.10.2-debian-10-r0 ) 作為我的注冊中心，首先我使用 gradle 添加 spring consul 依賴項( 2.2.7.RELEASE )：

implementation "org.springframework.cloud:spring-cloud-starter-consul-discovery"

然后在我項目的application.properties中添加配置：

# registry center
spring.cloud.consul.host=consul-1630121482-headless.reddwarf-pro.svc.cluster.local
spring.cloud.consule.port=8500
spring.cloud.consul.enabled=true
spring.cloud.consul.discovery.health-check-interval=15s
spring.cloud.consul.discovery.instance-id= ${spring.application.name}:${vcap.application.instance_id:${spring.application.instance_id:${random.value}}}
spring.cloud.consul.discovery.prefer-ip-address= true
spring.cloud.consul.discovery.deregister=false
# service check failed, delete service
spring.cloud.consul.discovery.health-check-critical-timeout=10m

該寄存器可以注冊成功並且工作正常。 但是現在我面臨一個問題，即遺留服務沒有自動刪除。 我已經添加了注銷配置，為什么不起作用？ 為什么該服務仍然沒有自動注銷？ ` 這是我的 kubernetes yaml 配置：

我已經嘗試添加配置：

spring:
  application:
    name: dolphin-gateway
  cloud:
    consul:
      discovery:
        health-check-interval: 15s
        deregister: true
        health-check-critical-timeout: 5s
        instance-id: ${spring.application.name}:${vcap.application.instance_id:${spring.application.instance_id:${random.value}}}
        prefer-ip-address: true
      enabled: true
      host: consul-1630121482-headless.reddwarf-pro.svc.cluster.local

這是領事儀表板用戶界面： https ://consul.poemhub.top/ui/dc1/services/dolphin-gateway/instances。 這是無效的服務：

These worked for me.

    spring.cloud.consul.discovery.enabled=true
spring.cloud.consul.discovery.register=true
spring.cloud.consul.discovery.deregister=false
spring.cloud.consul.discovery.health-check-path=/context-path/actuator/health
spring.cloud.consul.discovery.health-check-interval=3s
spring.cloud.consul.discovery.health-check-timeout=3s
spring.cloud.consul.discovery.health-check-critical-timeout=5s
spring.cloud.consul.discovery.scheme=http
spring.cloud.consul.discovery.health-check-tls-skip-verify=true
spring.cloud.consul.discovery.prefer-ip-address=true
spring.cloud.consul.discovery.register-health-check=true
spring.cloud.consul.port=8500
spring.cloud.consul.host=consul-headless

Apply these in application.properties file.
