蜻蜓虫群领事服务发现 - 服务地址无效

Question

我正在开发Wildfly-Swarm应用，我想用Consul作为我的服务发现。所以我添加了拓扑 - 顾问分数，将我的Consul路径设置为project-defaults.yml并将@Advertise("service-name")添加到我的端点。

如果我使用

java –jar my-swarm-app.jar 

一切开始我的应用程序的工作就好了。

我的项目defaults.yml：

service: 
    catalog: 
    service-name: "service-name" 
swarm: 
    port: 
    offset: 501 
    consul: 
    url: "http://172.30.3.80:8500" 

但是，当我收拾我的泊坞窗图像内脂肪的罐子这个Dockerfile：

FROM openjdk:8-jre-alpine 
ADD my-swarm-app.jar /opt/my-swarm-app.jar 
EXPOSE 8581 
ENTRYPOINT ["java", "-jar", "-Djava.net.preferIPv4Stack=true", "/opt/my-swarm-app.jar"] 

构建：

docker build -f Dockerfile -t my-swarm-app . 

而且像这样运行它：

docker run -p 8581:8581 my-swarm-app 

我得到以下异常：

2017-09-26 15:17:54,240 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-4) MSC000001: Failed to start service swarm.topology.register.consent-service.http: org.jboss.msc.service.StartException in service swarm.topology.register.consent-service.http: com.orbitz.consul.ConsulException: Invalid service address

难道我做错了什么？

编辑： 我试着用consul-api自我实现服务发现。

 <dependency> 
      <groupId>com.ecwid.consul</groupId> 
      <artifactId>consul-api</artifactId> 
      <version>1.2.4</version> 
     </dependency> 

像这样：

@ApplicationScoped 
public class Config { 

    private ConsulClient client; 

    @Inject 
    @ConfigurationValue("swarm.http.port") 
    private Integer port; 

    public void init(@Observes @Initialized(ApplicationScoped.class) ServletContext context) { 
     client = new ConsulClient("http://172.30.3.80:8500"); 

     // register new service with associated health check 
     NewService newService = new NewService(); 
     newService.setId("myapp_02"); 
     newService.setTags(Collections.singletonList("EU-East")); 
     newService.setName("myapp_aaa"); 
     newService.setPort(port); 

     client.agentServiceRegister(newService); 
    } 
} 

而且其内部搬运工形象的工作。这可能是Wildfly-Swarm拓扑部分中的一个错误，或者我缺少一些配置？

编辑2： 我发现问题是与野蝇群参数-Djava.net.preferIPv4Stack=true。当我运行jar文件使用此参数，我得到相同的异常，但如果我删除它Dockerfile创建码头工人形象，并运行它，我得到这个异常：

Answer 1

看起来类似于this的问题。

您可以尝试将swarm.bind.address: 127.0.0.1添加到yml配置。
