如您所见，没有stack命令。

更新1

我还认为stack命令会显示在群集节点中吗？因此，我使用docker-machine ssh myvm1 'docker'进行了测试。 不幸的是，仍然没有stack命令

Answer 1

我同意@novaline，这似乎是文档中的错误。

此外，如果您尝试docker stack --help

您将获得：

Usage:  docker stack COMMAND

Manage Docker stacks

Options:


Commands:
  deploy      Deploy a new stack or update an existing stack
  ls          List stacks
  ps          List the tasks in the stack
  rm          Remove one or more stacks
  services    List the services in the stack

Run 'docker stack COMMAND --help' for more information on a command.

Answer 2

命令在那里，但是...

$ docker stack ls
Error response from daemon: This node is not a swarm manager. Use "docker swarm init" or "docker swarm join" to connect this node to swarm and try again.

您必须以群体模式运行Docker引擎。

来自Docs：

以群体模式运行Docker Engine时，可以使用docker stack deploy将完整的应用程序堆栈部署到群体。 deploy命令接受Compose file形式的堆栈描述。


注意：如果您要在本地开发环境中尝试操作，请使用docker swarm init将引擎置于集群模式。

如果您已经在运行多节点群集，请记住，所有docker stack和docker service命令都必须从 manager节点运行。
