docker stack is not in the list of docker commands.

But it works fine. Is it a bug or what? Here is the command list of docker:

As you can see, there is no stack command.

Here is my docker version: 

☁  docker-research [master] ⚡  docker version
Client:
 Version:   18.03.0-ce
 API version:   1.37
 Go version:    go1.9.4
 Git commit:    0520e24
 Built: Wed Mar 21 23:06:22 2018
 OS/Arch:   darwin/amd64
 Experimental:  false
 Orchestrator:  swarm

Server:
 Engine:
  Version:  18.05.0-ce
  API version:  1.37 (minimum version 1.12)
  Go version:   go1.10.1
  Git commit:   f150324
  Built:    Wed May  9 22:20:42 2018
  OS/Arch:  linux/amd64
  Experimental: false

update 1

I also think does stack command will show in a swarm node? So, I do a test using docker-machine ssh myvm1 'docker'. Unfortunately, there is still no stack command

I agree with @novaline it seems like a bug in the documentation.

Also, if you try docker stack --help

You will get:

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.

The command is there, but...

$ 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.

you have to run the Docker Engine in swarm mode.

from the Docs:

When running Docker Engine in swarm mode, you can use docker stack deploy to deploy a complete application stack to the swarm. The deploy command accepts a stack description in the form of a Compose file.

Note: If you're trying things out on a local development environment, you can put your engine into swarm mode with docker swarm init.

If you've already got a multi-node swarm running, keep in mind that all docker stack and docker service commands must be run from a manager node.
