不同节点上的Docker swarm服务无法通信

Question

我在swarm模式下运行docker，我在相同的覆盖网络上运行了一些服务但节点不同。

我试图让这些服务的节点能够相互通信;这工作正常，直到我尝试交叉节点。

以下是我的网络定义，来自一个节点：

{
    "Name": "my-nw",
    "Id": "0jk0h0sor0839i2j91rz8b7c9",
    "Scope": "swarm",

    "EnableIPv6": false,
    "IPAM": {

            {
                "Subnet": "10.0.0.0/24",
                "Gateway": "10.0.0.1"
            }
        ]
    },
    "Internal": false,
    "Containers": {
        "0467076e0f3b3618115a4d023e78a74921eb6ef7c7ba1e5baeffe1ea4500ee1e": {

        },
        "4554f04efa9c2d66e584fefa3d610314761f8dc6599f3723e878e6e5326cd21e": {

            "IPv4Address": "10.0.0.5/24",
            "IPv6Address": ""
        }
    },
    "Options": {
        "com.docker.network.driver.overlay.vxlanid_list": "257",
        "encrypted": ""
    },
    "Labels": {}
}

这是来自另一个节点：

{
    "Name": "my-nw",
    "Id": "0jk0h0sor0839i2j91rz8b7c9",
    "Scope": "swarm",
    "Driver": "overlay",
    "EnableIPv6": false,
    "IPAM": {

        "Config": [
            {
                "Subnet": "10.0.0.0/24",
                "Gateway": "10.0.0.1"
            }
        ]
    },
    "Internal": false,
    "Containers": {
        "68ae6de87b418168fdc708ea015d3b4130911124eab9821902d03de59eb91264": {
            "Name": "sleepy_fermi.1.azu3d6fdjq1jovspok3xn0rrk",
            "EndpointID": "dc485439790fa586c8c592f2e53f8bdb7e50142c560538349a70e2cda6e065a4",
            "MacAddress": "02:42:0a:00:00:03",
            "IPv4Address": "10.0.0.3/24",
            "IPv6Address": ""
        },
        "f4fdacd84bf8b40dace568d3ced1635bec0f982f03566e043e59c29eccc2bf19": {
            "Name": "tiny_montalcini.1.a3ovorl23ak351gozxr9o7nvt",
            "EndpointID": "f3951430836fbb056e559e43de921b8c437f72d1ee0c59b4179220c6c0ea0eee",
            "MacAddress": "02:42:0a:00:00:07",
            "IPv4Address": "10.0.0.7/24",
            "IPv6Address": ""
        }
    },
    "Options": {
        "com.docker.network.driver.overlay.vxlanid_list": "257",
        "encrypted": ""
    },
    "Labels": {}
}

所以，例如，我可以卷曲sleepy_fermi.4。来自sleepy_fermi.5。但不是来自sleepy_fermi.3（ip-address也不起作用，因此它不仅仅是名称查找问题）。
