Question

我的系统昨天崩溃，我无法恢复它。我没有说明这一点，所以我不知道所有细节，但请询问所需的任何细节。过去，在任何VM重启时，系统都会自动开始工作，但在此次崩溃之后它就再也没有了：

这是我的po myView.dump()输出

docker info

我的docker节点ls输出：

docker node inspect swarm-worker-1

任何想法如何让它恢复工作？

Answer 1

在swarm worker上执行docker swarm leave，然后在master run docker swarm join-token worker上执行生成的令牌命令，返回worker。它应该开始工作。

崩溃可能导致了一个问题。这会破坏swarm的状态，因此你需要重新创建它

docker containers不会自动与docker swarm一起启动
