我正在开发Wildfly-Swarm应用程序,我想使用Consul作为我的服务发现.所以我添加了topology-consul分数,在project-defaults.yml中设置了Consul路径,并将@Advertise(“service-name”)添加到了我的Endpoint.
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"
但是当我使用这个Dockerfile将我的胖罐包装在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 .
并运行它：
docker run -p 8581:8581 my-swarm-app
我得到以下异常：

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.
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图像中工作.这可能是Wildfly-Swarm拓扑分数中的一个错误,还是我错过了一些配置？

我发现问题出在wildfly-swarm paramater -Djava.net.preferIPv4Stack = true.当我使用此参数运行jar文件时,我得到相同的异常,但如果我删除Dockerfile以创建docker镜像并运行它,我会得到以下异常：
