Docker 群部署失败，'Pool overlaps with other one'

Question

我有一个正在工作的docker容器，我已经可以使用它的docker-compose.yml成功运行它了。

现在尝试切换到docker swarm init。

结果：当我尝试部署到docker swarm时，我的容器启动失败，Pool overlaps with other one。可能是什么问题？

docker stack deploy -c docker-compose.yml docker-test

我自己并没有创建任何网络，只是依靠docker默认值：

#installed networks by docker + docker-compose + docker swarm
$docker network ls

我的docker配置可能在cat /etc/docker/daemon.json:中如下所示

{
...
"default-address-pools":
[
{
"base": "10.0.0.0/16",
"size": 24
}
]
}

这可能与docker群体网络相冲突。我将上面的更改为11.0.0.0/16，然后使用docker system prune清除所有网络，然后再次使用docker swarm init。
