Docker Compose 网络多播

Question

我正在尝试通过多播将不同的野蝇相互连接。如果我在我的机器上本地运行 wildflys，它们会通过 226.0.1.1 相互通信

但在 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:

        }
    }
]

有人看到我的问题了吗？

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(bind)到容器的本地地址，更改集群pw并使用ipv4

我还更新了 GitHub 存储库以显示当前正在运行的集群
