It's not the same. Strangely the docker-swarm tutorial doesn't mention swarm mode. I wasn't able to follow it successfully with Docker 1.12. That was when I realized docker-swarm != swarm mode, so I tried the swarm mode tutorial instead, and it worked as expected.

Maybe docker-swarm is not supported anymore with 1.12? It was all pretty confusing.

>Maybe docker-swarm is not supported anymore with 1.12?

I am using docker-swarm with 1.12 so it's definitely supported. Yea I am really confused too :D.

Originally, there was the stand alone version of docker swarm, invoked using "docker-swarm". This was more difficult to set up than version 1.12's new swarm mode, invoked using "docker swarm", which does almost the same thing, but more succinctly. Presumably, they chose the same name because they serve the same purpose and, if the latter is set to replace the former, why come up with a new name for basically the same concept?

>if the latter is set to replace the former

Do you know if there was any guidance by docker team on this? Seems like there is active development going on for both docker-swarm and swarm-mode.

Development is mainly in swarm mode, but yes the older swarm is still supported, it is just an application that uses docker so will always work.

I guess my main confusion is when would someone choose to use docker-swarm over swarm-mode.

https://github.com/docker/swarm is going away.

https://github.com/docker/swarmkit is what gets integrated into Docker engine as of docker-1.12.0.

>https://github.com/docker/swarm is going away.

Their readme says

"Docker does not currently have a plan to deprecate Docker Swarm."

Do you know if they officially say otherwise elsewhere?
