野蛮群体领事服务发现 – 服务地址无效
我正在开发Wildfly Swarm应用程序，我想用Consul作为我的服务发现。 所以我添加了拓扑 – @Advertise("service-name")分数，在我的端点中设置了我的Consulpath到project-defaults.yml并添加了@Advertise("service-name") 。
如果我开始使用我的应用程序
java –jar my-swarm-app.jar
一切正常。
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，当我用这个Dockerfile将我的胖jar包装到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"]
build立它：
docker build -f Dockerfile -t my-swarm-app .
像这样运行：
docker run -p 8581:8581 my-swarm-app
我得到以下exception：
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 at org.wildfly.swarm.topology.deployment.RegistrationAdvertiser.start(RegistrationAdvertiser.java:79) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1948) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1881) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: com.orbitz.consul.ConsulException: Invalid service address at com.orbitz.consul.AgentClient.register(AgentClient.java:180) at com.orbitz.consul.AgentClient.register(AgentClient.java:184) at org.wildfly.swarm.topology.consul.runtime.Advertiser.advertise(Advertiser.java:65) at org.wildfly.swarm.topology.consul.runtime.ConsulTopologyConnector.advertise(ConsulTopologyConnector.java:60) at org.wildfly.swarm.topology.deployment.RegistrationAdvertiser.start(RegistrationAdvertiser.java:77) ... 5 more
难道我做错了什么？
编辑：我已经尝试使用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); } }
它在Docker镜像中工作。 这可能是Wildfly-Swarm拓扑部分中的一个错误，或者我缺less一些configuration？
编辑2：我发现这个问题是与蜻蜓群参数-Djava.net.preferIPv4Stack=true 。 当我用这个参数运行jar文件，我得到同样的exception，但如果我删除它的Dockerfile创builddocker的形象和运行它，我得到这个exception：

这里是链接到github项目，您可以重现错误： https ： //github.com/pkristja/wildfly-swarm-consul-demo
它看起来类似于这个问题。
你可以尝试添加swarm.bind.address: 127.0.0.1到ymlconfiguration。
