java - Wildfly-Swarm Consul服务发现-无效的服务地址

我正在开发Wildfly-Swarm应用，我想使用Consul作为我的服务发现。因此，我添加了拓扑Consul分数，在project-defaults.yml中设置了Consul路径，并将@Advertise("service-name")添加到了Endpoint。

如果我使用以下方式启动应用程序

java –jar my-swarm-app.jar

一切正常。

我的project-defaults.yml:

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

但是，当我用这个Dockerfile将胖子打包到Docker镜像中时:

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"]

建立它:

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

并像这样运行它:

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:
我尝试使用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);
    }
}

及其在docker镜像中的工作方式。这可能是Wildfly-Swarm拓扑部分中的错误，还是我缺少某些配置？

我发现问题出在野蝇群参数-Djava.net.preferIPv4Stack=true上。当我使用此参数运行jar文件时，会遇到相同的异常，但是如果我将其删除以创建docker镜像的Dockerfile并运行，则会出现此异常:

这是github项目的链接，您可以在其中重现该错误:

最佳答案

它看起来类似于this问题。

您可以尝试将swarm.bind.address: 127.0.0.1添加到yml配置中吗？
