【问题描述】：
我有一个 2 个节点的 swarm（都使用 docker 19.03.1），但我遇到了麻烦 - 我经常收到
"Pool overlaps with other one on this address space" module=node/agent/taskmanager"
使用已发布端口创建服务时的消息。
群体被创造为香草：
manager@ docker swarm init
worker@ docker swarm join...
我创建了一个覆盖网络
manager@ docker network create -d overlay ids-net --attachable
在两个节点上创建一个简单的服务是可行的：
manager@ docker service create --replicas 2 --network ids-net hashicorp/http-echo -text="hello world"
结果：
image hashicorp/http-echo:latest could not be accessed on a registry to record
its digest. Each node will access hashicorp/http-echo:latest independently,
possibly leading to different nodes running different
versions of the image.

overall progress: 2 out of 2 tasks
1/2: running [==================================================>]
2/2: running [==================================================>]
verify: Service converged
发出以下导致无限循环：
manager@ docker service create --replicas 2 --publish published=5678,target=5678 --network ids-net hashicorp/http-echo -text="hello world"
显示如下：
image hashicorp/http-echo:latest could not be accessed on a registry to record
its digest. Each node will access hashicorp/http-echo:latest independently,
possibly leading to different nodes running different
versions of the image.

我认为覆盖网络存在问题。
经理收益率上的manager@ docker inspect <network id>：

"IP": "192.168.100.92"
}
]
}
]
在工作节点上，未创建网络。 （对吗？）
这是两台机器根据@BMitch 的要求输出的ip r：
manager@ ip r
default via 192.168.100.11 dev ens192 onlink
10.255.0.0/24 dev docker0 proto kernel scope link src 10.255.0.1
10.255.1.0/24 dev br-686969a42803 proto kernel scope link src 10.255.1.1
10.255.23.0/24 dev docker_gwbridge proto kernel scope link src 10.255.23.1
10.255.42.0/24 dev br-c03d759e1553 proto kernel scope link src 10.255.42.1
192.168.100.0/24 dev ens192 proto kernel scope link src 192.168.100.92
worker@ ip r
default via 192.168.100.11 dev eth0 onlink
10.254.0.0/24 dev docker0 proto kernel scope link src 10.254.0.1
10.255.3.0/24 dev docker_gwbridge proto kernel scope link src 10.255.3.1
10.255.4.0/24 dev br-88f241f38441 proto kernel scope link src 10.255.4.1
192.168.100.0/24 dev eth0 proto kernel scope link src 192.168.100.106
这是来自manager的/etc/docker/daemon.json：
manager@ cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://repo.ids.net"],
"default-address-pools": [
{"base":"10.255.255.0/16","size":24}
]
}
worker 看起来不同：
manager@ cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://repo.ids.net"],
"default-address-pools": [
{"base":"10.254.255.0/16","size":24}
]
}
这是入口网络配置：
root@docker:/etc/nginx/conf.d# docker network inspect ozjtk12iougu
[
{
"Name": "ingress",
"Id": "ozjtk12iougu8fqjliqspvxx2",
"Created": "2019-07-31T07:36:57.368162913Z",
"Scope": "swarm",
"Driver": "overlay",
"EnableIPv6": false,
"IPAM": {
"Driver": "default",
"Options": null,
"Config": [
{
"Subnet": "10.255.0.0/16",
"Gateway": "10.255.0.1"
}
]
},
"Internal": false,
"Attachable": false,
"Ingress": true,
"ConfigFrom": {
"Network": ""
},
"ConfigOnly": false,
"Containers": null,
"Options": {
"com.docker.network.driver.overlay.vxlanid_list": "4096"
},
"Labels": null
}
]
我已多次清除两个系统，并从头开始重新启动两个服务器。
有人可以指导我吗？
谢谢 M
