docker - 创建 docker swarm 网络时未应用覆盖驱动程序

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，都没有附加驱动程序。

  1. 如果我尝试将服务附加到网络，进程就会无限挂起。
  2. 如果我创建了一个服务但没有将其连接到网络，它会立即运行。
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

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

我不明白为什么它不添加驱动程序。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:

  1. 删除所有节点并创建一个新的群
  2. 删除入口网络并在 the instructions here 之后创建一个新网络
  3. 尝试完成演练 here但无法通过创建服务 2。
  4. 重启所有节点

任何建议或指向正确的方向将不胜感激!我已经被困在这里 48 小时了。

最佳答案

已解决!

问题最终是:

  1. 节点都在 10.0.0.x
  2. 我在初始化 swarm 时设置了 --default-addr-pool 10.10.0.0/24

我尝试使用 --driver overlay 创建的任何网络最终都会没有任何子网或网关信息。

我是如何解决这个问题的:

我能够在创建自定义网络时使用 --subnet 标志来解决它。
