Question

我正在尝试在docker swarm上部署vertx3服务，但是当我运行

时

$ curl localhost:4000
   curl: (7) Failed to connect to localhost port 4000: Connection refused

我无法弄清楚如何使它工作，帮助赞赏。请参阅下面的代码和更多信息。

这是我的vertx3应用程序

import io.vertx.core.AbstractVerticle;
import io.vertx.core.Future;

public class MainVerticle extends AbstractVerticle {
  @Override
  public void start(Future<Void> fut) {
    vertx.createHttpServer().requestHandler(r -> {
        r.response().end("<h1>Powered by Vert.x3</h1>");
    }).listen(8080, result -> {
      if (result.succeeded()) {
          fut.complete();
      } else {
            fut.fail(result.cause());
          }
      });
  }
}

这是我的dockerfile

FROM vertx/vertx3
ENV VERTICLE_NAME com.shop.services.products.MainVerticle
ENV VERTICLE_FILE target/products-3.5.1.jar
ENV VERTICLE_HOME /usr/verticles
EXPOSE 8080
COPY $VERTICLE_FILE $VERTICLE_HOME/
WORKDIR $VERTICLE_HOME
ENTRYPOINT ["sh", "-c"]
CMD ["exec vertx run $VERTICLE_NAME -cp $VERTICLE_HOME/*"]

这是我的docker-compose.yml

version: "3"
services:
  web:
    image: sergionava89/products:v1
    deploy:
      replicas: 5
      resources:
        limits:
          cpus: "0.1"
          memory: 50M
      restart_policy:
        condition: on-failure
    ports:
      - "4000:8080"
    networks:
      - webnet
networks:
  webnet:

我尝试运行本地docker swarm

docker swarm init

然后我收到此消息

Error response from daemon: could not choose an IP address to advertise since this system has multiple addresses on interface enp0s25 (2a02:c7d:501a:f200:84fc:532e:737a:7a21 and 2a02:c7d:501a:f200:ad08:5748:44d4:6726) - specify one with --advertise-addr

所以我运行以下

docker swarm init --advertise-addr 2a02:c7d:501a:f200:84fc:532e:737a:7a21

然后启动容器

docker stack deploy -c docker-compose.yml shop

我得到了

Creating network shop_webnet
Creating service shop_web

当我尝试点击端点时，我得到了

$ curl localhost:4000
   curl: (7) Failed to connect to localhost port 4000: Connection refused

码头服务的输出
