【问题描述】：
我正在使用 docker swarm 并尝试使用 overlay 驱动程序创建网络。
每当我创建网络时，驱动程序都不会附加。
- 如果我尝试将服务附加到网络，该进程将无限挂起。
- 如果我创建一个服务没有将其连接到网络，它会立即工作。
pi@node3:~ $ docker network ls
NETWORK ID NAME DRIVER SCOPE
a1cc2e1f4f2b bridge bridge local
83597f713bcf docker_gwbridge bridge local
277f1166485e host host local
fs2vvjeuejxc ingress overlay swarm
5d0ce08c744c none null local
pi@node3:~ $ docker network create --driver overlay test
4bfkahhkhrblod2t79yd83vws
pi@node3:~ $ docker network ls
NETWORK ID NAME DRIVER SCOPE
a1cc2e1f4f2b bridge bridge local
83597f713bcf docker_gwbridge bridge local
277f1166485e host host local
fs2vvjeuejxc ingress overlay swarm
5d0ce08c744c none null local
4bfkahhkhrbl test swarm
我不明白为什么它没有添加驱动程序。我怀疑它与入口网络设置有关，但我被困在这里进行故障排除。

我尝试过的：
- 删除所有节点并创建一个新群
- 删除入口网络并在the instructions here 之后创建一个新网络
- 尝试完成演练here，但无法通过 Create the Services 2。
- 重启所有节点
