Docker撰写网络多播

Question

我试图通过多播将不同的野生蜻蜓相互连接起来。如果我在我的机器上本地运行野生蝇，他们会通过226.0.1.1互相交谈

但是在docker compose中，网络中没有通信。

我当前的撰写文件如下所示：

version: '3.5'
services:

  wildfly1:
    build: ./wildfly_image
    image: wildfly:latest
    environment:
    - WILDFLYNAME=wildfly1
    networks:
      wildfly_network:

  wildfly2:
    build: ./wildfly_image
    image: wildfly:latest
    environment:
    - WILDFLYNAME=wildfly2
    networks:
      wildfly_network:

networks: 
  wildfly_network:
    ipam:
      driver: default

如果我运行docker network inspect <wildfly_network>我得到以下结果：

        }
    }
]

有人看到我的问题吗？

谢谢

Answer 1

我用以下命令解决了这个问题：

ENTRYPOINT /opt/jboss/wildfly/bin/standalone.sh -b=0.0.0.0 -bmanagement=0.0.0.0 -Djboss.server.default.config=standalone-full-ha.xml -Djboss.node.name=${WILDFLY_NAME} -Djava.net.preferIPv4Stack=true -Djgroups.bind_addr=$(hostname -i) -Djboss.messaging.cluster.password=${CLUSTER_PW}

您必须将jgroup地址绑定到容器的本地地址，更改群集pw并使用ipv4

我还更新了GitHub仓库以显示当前正在运行的集群

如果网络的唯一目的是使您的服务可访问，请尝试直接访问docker compose中的服务，例如http://wildfly1，http://wildfly2。 Docker compose应该在默认网络中添加两个服务，并在compose中将服务名称提供给其他服务。欲了解更多信息，请参阅docker doc

version: '3.5'
services:

  wildfly1:
    build: ./wildfly_image
    image: wildfly:latest
    environment:
    - WILDFLYNAME=wildfly1

  wildfly2:
    build: ./wildfly_image
    image: wildfly:latest
    environment:
    - WILDFLYNAME=wildfly2
