I have searched over stackoverflow & tried alot of solutions but with no result.

I have 2 containers one is for eureka server and another one for spring cloud gateway.

I’m running these 2 containers with docker-compose but spring-cloud-gateway didn’t register to eureka server.

I’m using https. On localhost everything is working as expected but when I jumped to containers this is the problem of unregistered clients.

eureka.server.yml:

eureka:
  client:
    fetch-registry: false
    register-with-eureka: false
  instance:
    secure-port-enabled: true
    non-secure-port-enabled: false
server:
    port: 8761
    ssl:
      enabled: true
      key-alias: statement
      key-store: classpath:statement-keystore.p12
      key-store-password: secret
      key-store-type: PKCS12
spring:
    application:
        name: netflix-eureka

spring.cloud.gateway.yml:

eureka:
    instance:
        nonSecurePortEnabled: false
        securePortEnabled: true
        securePort: 8765
        prefer-ip-address: true
    client:
        registerWithEureka: true
        fetchRegistry: true
