docker集装箱不会自动启动泊坞群

我的系统像昨天一样崩溃，我一直无法恢复。 我没有设置这个，所以我不知道所有的细节，但请要求任何细节。 它曾经是在任何虚拟机重启系统会自动开始工作，但在这次崩溃后，它不再是：

这是我的docker info输出

我的docker节点ls输出：

这里是docker node inspect swarm-manager-1

任何想法如何恢复工作？

Answer 1

在swarm worker上执行docker swarm leave ，然后在master上run docker swarm join-token worker并在run docker swarm join-token worker执行结果令牌命令。 它应该开始工作。

崩溃可能导致了一个问题。 这破坏了群体的状态，因此你需要重新创build它
