docker堆栈命令不在docker命令列表中。

如您所见，没有stack命令。

这是我的码头版本：

更新1

我还认为stack命令会显示在群集节点中吗？所以，我用docker-machine ssh myvm1 'docker'做了一个测试。不幸的是，仍然没有stack 命令。

Answer 1

我同意@novaline，这似乎是文档中的一个bug。

另外，如果您尝试docker stack --help

你会得到：

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.

你必须用蜂群模式运行码头引擎。

来自文档

在群集模式下运行Docker引擎时，可以使用docker stack deploy将完整的应用程序堆栈部署到群集中。deploy命令以合成文件的形式接受堆栈描述。 Note：如果您要在本地开发环境上进行尝试，可以使用docker swarm init将引擎放入群集模式中。 如果已经有多节点群在运行，请记住，所有docker stack和docker service命令都必须从管理器节点中运行。
